include Unresolved Resonance Region GROUPIE
self-shielding. GROUPIE
*Added Unresolved self-shielding by GROUPIE
Extrapolating cross section moments GROUPIE
from Resolved (supersedes URRDO and GROUPIE
URRFIT codes). GROUPIE
*Added entire self-shielding array to GROUPIE
memory - previously only one group GROUPIE
results were in memory - saving ALL GROUPIE

groups completely inside the URR + GROUPIE
per ends for MF/MT=2/152 & 153 output.GROUPIE
*Small shielding < 0.1 % = accuracy GROUPIE
of reconstructed data. GROUPIE
*Forced no self-shielding at upper end GROUPIE
of unresolved = match high energy GROUPIE
tabulated. GROUPIE
*Corrected PLOTTAB output if no URR GROUPIE
fit - it was outputting EMPTY tables GROUPIE
for original and fit moments, which GROUPIE
in this case did not exist. GROUPIE

AUTHORS MESSAGE GROUPIE
--------------- GROUPIE
THE REPORT DESCRIBED ABOVE IS THE LATEST PUBLISHED DOCUMENTATION GROUPIE
FOR THIS PROGRAM. HOWEVER, THE COMMENTS BELOW SHOULD BE CONSIDEREDGROUPIE
THE LATEST DOCUMENTATION INCLUDING ALL RECENT IMPROVEMENTS. PLEASEGROUPIE
READ ALL OF THESE COMMENTS BEFORE IMPLEMENTATION, PARTICULARLY GROUPIE
THE COMMENTS CONCERNING MACHINE DEPENDENT CODING. GROUPIE
GROUPIE
AT THE PRESENT TIME WE ARE ATTEMPTING TO DEVELOP A SET OF COMPUTERGROUPIE
INDEPENDENT PROGRAMS THAT CAN EASILY BE IMPLEMENTED ON ANY ONE GROUPIE
OF A WIDE VARIETY OF COMPUTERS. IN ORDER TO ASSIST IN THIS PROJECTGROUPIE
IT WOULD BE APPECIATED IF YOU WOULD NOTIFY THE AUTHOR OF ANY GROUPIE
COMPILER DIAGNOSTICS, OPERATING PROBLEMS OR SUGGESTIONS ON HOW TO GROUPIE
IMPROVE THIS PROGRAM. HOPEFULLY, IN THIS WAY FUTURE VERSIONS OF GROUPIE
THIS PROGRAM WILL BE COMPLETELY COMPATIBLE FOR USE ON YOUR GROUPIE
COMPUTER. GROUPIE
GROUPIE
PURPOSE GROUPIE
------- GROUPIE
THIS PROGRAM IS DESIGNED TO CALCULATE ANY COMBINATION OF GROUPIE
THE FOLLOWING QUANTITIES FROM LINEARLY INTERPOLABLE TABULATED GROUPIE
CROSS SECTIONS IN THE ENDF/B FORMAT GROUPIE
GROUPIE
(1) UNSHIELDED GROUP AVERAGED CROSS SECTIONS GROUPIE
(2) BONDARENKO SELF-SHIELDED GROUP AVERAGED CROSS SECTIONS GROUPIE
(3) MULTI-BAND PARAMETERS GROUPIE
GROUPIE
IN THE FOLLOWING FOR SIMPLICITY THE ENDF/B TERMINOLOGY--ENDF/B GROUPIE
TAPE--WILL BE USED. IN FACT THE ACTUAL MEDIUM MAY BE TAPE, CARDS, GROUPIE
DISK OR ANY OTHER MEDIUM. GROUPIE
GROUPIE
ENDF/B FORMAT GROUPIE
------------- GROUPIE
THIS PROGRAM ONLY USES THE ENDF/B BCD OR CARD IMAGE FORMAT (AS GROUPIE
OPPOSED TO THE BINARY FORMAT) AND CAN HANDLE DATA IN ANY VERSION GROUPIE
OF THE ENDF/B FORMAT (I.E., ENDF/B-I, II,III, IV OR V FORMAT). GROUPIE
GROUPIE
IT IS ASSUMED THAT THE DATA IS CORRECTLY CODED IN THE ENDF/B GROUPIE
FORMAT AND NO ERROR CHECKING IS PERFORMED. IN PARTICULAR IT IS GROUPIE
ASSUMED THAT THE MAT, MF AND MT ON EACH CARD IS CORRECT. SEQUENCE GROUPIE
NUMBERS (COLUMNS 76-80) ARE IGNORED ON INPUT, BUT WILL BE GROUPIE
CORRECTLY OUTPUT ON ALL CARDS. THE FORMAT OF SECTION MF=1, MT=451 GROUPIE
AND ALL SECTIONS OF MF= 3 MUST BE CORRECT. THE PROGRAM COPIES ALL GROUPIE
OTHER SECTION OF DATA AS HOLLERITH AND AS SUCH IS INSENSITIVE TO GROUPIE
THE CORRECTNESS OR INCORRECTNESS OF ALL OTHER SECTIONS. GROUPIE
GROUPIE
ALL FILE 3 CROSS SECTIONS THAT ARE USED BY THIS PROGRAM MUST BE GROUPIE
LINEARLY INTERPOLABLE IN ENERGY AND CROSS SECTION (ENDF/B GROUPIE
INTERPOLATION LAW 2). FILE 3 BACKGROUND CROSS SECTIONS MAY BE MADEGROUPIE
LINEARLY INTERPOLABLE USING PROGRAM LINEAR (UCRL-50400, VOL. 17, GROUPIE
PART A). THE RESONANCE CONTRIBUTION MAY BE ADDED TO THE BACKGROUNDGROUPIE
CROSS SECTIONS USING PROGRAM RECENT (UCRL-50400, VOL. 17, PART B).GROUPIE
IF THIS PROGRAM FINDS THAT THE FILE 3 CROSS SECTIONS ARE NOT GROUPIE
LINEARLY INTERPOLABLE THIS PROGRAM WILL TERMINATE EXECUTION. GROUPIE
GROUPIE
CONTENTS OF OUTPUT GROUPIE
------------------ GROUPIE
IF ENDF/B FORMATTED OUTPUT IS REQUESTED ENTIRE EVALUATIONS ARE GROUPIE
OUTPUT, NOT JUST THE MULTI-GROUPED FILE 3 CROSS SECTIONS, E.G. GROUPIE
ANGULAR AND ENERGY DISTRIBUTIONS ARE ALSO INCLUDED. GROUPIE
GROUPIE
DOCUMENTATION GROUPIE
------------- GROUPIE
THE FACT THAT THIS PROGRAM HAS OPERATED ON THE DATA IS DOCUMENTED GROUPIE
BY THE ADDITION OF THREE COMMENT CARDS AT THE END OF EACH GROUPIE
HOLLERITH SECTION TO DESCRIBE THE GROUP STRUCTURE AND WEIGHTING GROUPIE
SPECTRUM, E.G. GROUPIE
GROUPIE
********************** PROGRAM GROUPIE (2021-1) *************** GROUPIE
UNSHIELDED GROUP AVERAGES USING 69 GROUPS (WIMS) GROUPIE
MAXWELLIAN, 1/E, FISSION TO CONSTANT WEIGHTING SPECTRUM GROUPIE
GROUPIE
THE ORDER OF ALL SIMILAR COMMENTS (FROM LINEAR, RECENT AND SIGMA1)GROUPIE
REPRESENTS A COMPLETE HISTORY OF ALL OPERATIONS PERFORMED ON GROUPIE
THE DATA. GROUPIE
GROUPIE
THESE COMMENT CARDS ARE ONLY ADDED TO EXISTING HOLLERITH SECTIONS,GROUPIE
I.E., THIS PROGRAM WILL NOT CREATE A HOLLERITH SECTION. THE FORMATGROUPIE
OF THE HOLLERITH SECTION IN ENDF/B-V DIFFERS FROM THE THAT OF GROUPIE
EARLIER VERSIONS OF ENDF/B. BY READING AN EXISTING MF=1, MT=451 GROUPIE
IT IS POSSIBLE FOR THIS PROGRAM TO DETERMINE WHICH VERSION OF GROUPIE
THE ENDF/B FORMAT THE DATA IS IN. WITHOUT HAVING A SECTION OF GROUPIE
MF=1, MT=451 PRESENT IT IS IMPOSSIBLE FOR THIS PROGRAM TO GROUPIE
DETERMINE WHICH VERSION OF THE ENDF/B FORMAT THE DATA IS IN, AND GROUPIE
AS SUCH IT IS IMPOSSIBLE FOR THE PROGRAM TO DETERMINE WHAT FORMAT GROUPIE
SHOULD BE USED TO CREATE A HOLLERITH SECTION. GROUPIE
GROUPIE
REACTION INDEX GROUPIE
-------------- GROUPIE
THIS PROGRAM DOES NOT USE THE REACTION INDEX WHICH IS GIVEN IN GROUPIE
SECTION MF=1, MT=451 OF EACH EVALUATION. GROUPIE
GROUPIE
THIS PROGRAM DOES NOT UPDATE THE REACTION INDEX IN MF=1, MT=451. GROUPIE
THIS CONVENTION HAS BEEN ADOPTED BECAUSE MOST USERS DO NOT GROUPIE
REQUIRE A CORRECT REACTION INDEX FOR THEIR APPLICATIONS AND IT WASGROUPIE
NOT CONSIDERED WORTHWHILE TO INCLUDE THE OVERHEAD OF CONSTRUCTING GROUPIE
A CORRECT REACTION INDEX IN THIS PROGRAM. HOWEVER, IF YOU REQUIRE GROUPIE
A REACTION INDEX FOR YOUR APPLICATIONS, AFTER RUNNING THIS PROGRAMGROUPIE
YOU MAY USE PROGRAM DICTIN TO CREATE A CORRECT REACTION INDEX. GROUPIE
GROUPIE
SECTION SIZE GROUPIE
------------ GROUPIE
SINCE THIS PROGRAM USES A LOGICAL PAGING SYSTEM THERE IS NO LIMIT GROUPIE
TO THE NUMBER OF POINTS IN ANY SECTION, E.G., THE TOTAL CROSS GROUPIE
SECTION MAY BE REPRESENTED BY 200,000 DATA POINTS. GROUPIE
GROUPIE
SELECTION OF DATA GROUPIE
----------------- GROUPIE
THE PROGRAM SELECTS MATERIALS TO BE PROCESSED BASED EITHER ON GROUPIE
MAT (ENDF/B MAT NO.) OR ZA. THE PROGRAM ALLOWS UP TO 100 MAT OR GROUPIE
ZA RANGES TO BE SPECIFIED. THE PROGRAM WILL ASSUME THAT THE GROUPIE
ENDF/B TAPE IS IN EITHER MAT OR ZA ORDER, WHICHEVER CRITERIA IS GROUPIE
USED TO SELECT MATERIALS, AND WILL TERMINATE WHEN A MAT OR ZA GROUPIE
IS FOUND THAT IS ABOVE THE RANGE OF ALL REQUESTS. GROUPIE
GROUPIE
ENERGY ORDER AND UNITS GROUPIE
---------------------- GROUPIE
ALL ENERGIES (FOR CROSS SECTIONS, WEIGHTING SPECTRUM OR GROUP GROUPIE
BOUNDARIES) MUST BE IN UNITS OF EV AND MUST BE IN ASCENDING GROUPIE
NUMERICAL ORDER. GROUPIE
GROUPIE
ENERGY GRID GROUPIE
----------- GROUPIE
ALTHOUGH ALL REACTIONS MUST TO LINEARLY INTERPOLABLE, THEY DO NOT GROUPIE
ALL HAVE TO USE THE SAME ENERGY GRID. EACH REACTION CAN BE GIVEN GROUPIE
BY AN INDEPENDENT ENERGY GRID. THIS PROGRAM WILL PROCEED FROM GROUPIE
THE LOWEST TO HIGHEST ENERGY SELECTING EACH ENERGY INTERVAL OVER GROUPIE
WHICH ALL DATA, FOR ANY GIVEN CALCULATION, ARE ALL LINEARLY GROUPIE
INTERPOLABLE. GROUPIE
GROUPIE
GROUP STRUCTURE GROUPIE
--------------- GROUPIE
THIS PROGRAM IS DESIGNED TO USE AN ARBITRARY ENERGY GROUP GROUPIE
STRUCTURE WHERE THE ENERGIES ARE IN EV AND ARE IN INCREASING GROUPIE
ENERGY ORDER. THE MAXIMUM NUMBER OF GROUPS IS 20,000. GROUPIE
GROUPIE
THE USER MAY INPUT AN ARBITRARY GROUP STRUCTURE OR THE USER MAY GROUPIE
USE USE ONE OF THE BUILT-IN GROUP STRUCTURES. GROUPIE

GROUP AVERAGES GROUPIE
-------------- GROUPIE
THIS PROGRAM DEFINES GROUP AVERAGED CROSS SECTIONS AS... GROUPIE
GROUPIE
(INTEGRAL E1 TO E2) (SIGMA(E)*S(E)*WT(E)*DE) GROUPIE
AVERAGE = ----------------------------------------- GROUPIE
(INTEGRAL E1 TO E2) (S(E)*WT(E)*DE) GROUPIE

S(E) = ENERGY DEPENDENT WEIGHTING SPECTRUM GROUPIE
WT(E) = ENERGY DEPENDENT SELF-SHIELDING FACTOR. GROUPIE
GROUPIE
ENERGY DEPENDENT WEIGHTING SPECTRUM GROUPIE
----------------------------------- GROUPIE
THE ENERGY DEPENDENT WEIGHTING SPECTRUM IS GIVEN BY AN ARBITRARY GROUPIE
TABULATED LINERLY INTERPOLABLE FUNCTION WHICH CAN BE DESCRIBED GROUPIE
BY AN ARBITRARY NUMBER OF POINTS. THIS ALLOWS THE USER TO GROUPIE
SPECIFY ANY DESIRED WEIGHTING SPECTRUM TO ANY GIVEN DEGREE OF GROUPIE
ACCURACY. REMEMBER THAT THE PROGRAM WILL ASSUME THAT THE SPECTRUM GROUPIE
IS LINEARLY INTERPOLABLE BETWEEN TABULATED POINTS. THEREFORE THE GROUPIE
USER SHOULD USE ENOUGH POINTS TO INSURE AN ADEQUATE REPRESENTATIONGROUPIE
OF THE SPECTRUM BETWEEN TABULATED DATA POINTS. GROUPIE
GROUPIE
THE PRESENT VERSION OF THE CODE HAS THREE BUILT-IN WEIGHTING GROUPIE

UNSHIELDED GROUP AVERAGES GROUPIE
------------------------- GROUPIE
FOR UNSHIELDED AVERAGES THE SELF-SHIELDING FACTOR (WT(E)) IS SET GROUPIE
TO UNITY. THIS PROGRAM ALLOWS UP TO 20,000 GROUPS. GROUPIE
GROUPIE
SELF-SHIELDED GROUP AVERAGES GROUPIE
---------------------------- GROUPIE
IF SELF-SHIELDED AVERAGES AND/OR MULTI-BAND PARAMETERS ARE GROUPIE
CALCULATED THIS PROGRAM ALLOWS UP TO 20,000 GROUPS. SELF-SHIELDED GROUPIE
AVERAGES AND/OR MULTI-BAND PARAMETERS ARE CALCULATED FOR THE GROUPIE
TOTAL, ELASTIC, CAPTURE AND FISSION. GROUPIE
GROUPIE
FOR THE TOTAL, ELASTIC, CAPTURE AND FISSION THE PROGRAM USES A GROUPIE
WEIGHTING FUNCTION THAT IS A PRODUCT OF THE ENERGY DEPENDENT GROUPIE
WEIGHTING SPECTRUM TIMES A BONDERENKO TYPE SELF-SHIELDING FACTOR. GROUPIE
GROUPIE
WT(E) = S(E)/(TOTAL(E)+SIGMA0)**N GROUPIE
GROUPIE
WHERE... GROUPIE
GROUPIE
S(E) - ENERGY DEPENDENT WEIGHTING SPECTRUM (DEFINED BY GROUPIE
TABULATED VALUES AND LINEAR INTERPOLATION BETWEEN GROUPIE
TABULATED VALUES). GROUPIE
TOTAL(E) - ENERGY DEPENDENT TOTAL CROSS SECTION FOR ONE MATERIAL GROUPIE
(DEFINED BY TABULATED VALUES AND LINEAR INTERPOLATION GROUPIE
BETWEEN TABULATED VALUES). GROUPIE
SIGMA0 - CROSS SECTION TO REPRESENT THE EFFECT OF ALL OTHER GROUPIE
MATERIALS AND LEAKAGE (DEFINED WITHIN EACH GROUP TO BE GROUPIE
A MULTIPLE OF THE UNSHIELDED TOTAL CROSS SECTION WITHINGROUPIE
THAT GROUP OR POWERS OF 10 - INPUT OPTION). GROUPIE
N - A POSITIVE INTEGER (0, 1, 2 OR 3). GROUPIE
GROUPIE
THE PROGRAM WILL USE ONE ENERGY DEPENDENT WEIGHTING SPECTRUM S(E) GROUPIE
AND 25 DIFFERENT BONDERENKO TYPE SELF-SHIELDING FACTORS (25 SIGMA0GROUPIE
AND N COMBINATIONS) TO DEFINE 25 DIFFERENT AVERAGE CROSS SECTIONS,GROUPIE
FOR EACH REACTION, WITHIN EACH GROUP. GROUPIE
GROUPIE
THE 25 WEIGHTING FUNCTIONS USED ARE.... GROUPIE

AVERAGED CROSS SECTION WITHIN EACH GROUP. GROUPIE
GROUPIE
CALCULATION OF RESONANCE INTEGRALS GROUPIE
---------------------------------- GROUPIE
IN A PURE ELASTIC ISOTROPICALLY SCATTERING MATERIAL WITH A GROUPIE
CONSTANT CROSS SECTION THE SPECTRUM WILL BE 1/E AND THERE WILL GROUPIE
BE NO SELF-SHIELDING. GROUPIE
GROUPIE
IN THIS CASE IF THE CROSS SECTION VARIES WITH ENERGY THE GROUPIE
SPECTRUM WILL STILL BE 1/E AND THE SELF-SHIELDING FACTOR WILL GROUPIE
BE EXACTLY 1/SIG-TOT(E) - WHERE SIG-TOT(E) = SIG-EL(E), SINCE GROUPIE
THERE IS ONLY SCATTERING. GROUPIE
GROUPIE
IF WE HAVE AN INFINITELY DILUTE AMOUNT OF A MATERIAL UNIFORMLY GROUPIE
MIXED WITH A PURE ELASTIC ISOTROPICALLY SCATTERING MATERIAL WITH GROUPIE
A CONSTANT CROSS SECTION THE STANDARD DEFINITION OF THE RESONANCE GROUPIE
INTEGRAL CAN BE USED TO DEFINE REACTION RATES FOR EACH REACTION. GROUPIE
GROUPIE
THE RESONANCE INTEGRAL IS DEFINED AS, GROUPIE
GROUPIE
RI = (INTEGRAL E1 TO E2) (SIGMA(E)*S(E)*WT(E)*DE) GROUPIE
GROUPIE
WHERE NORMALLY, GROUPIE
S(E) = 1/E GROUPIE
WT(E) = 1 - NO SELF-SHIELDING GROUPIE
GROUPIE
FROM THE ABOVE DEFINITION OF GROUP AVERAGED CROSS SECTIONS THE GROUPIE
RESONANCE INTEGRAL IS, GROUPIE
GROUPIE
RI = AVERAGE * (INTEGRAL E1 TO E2) (S(E)*WT(E)*DE) GROUPIE
GROUPIE
FOR A 1/E SPECTRUM AND NO SELF-SHIELDING THIS REDUCES TO, GROUPIE
GROUPIE
RI = AVERAGE* LOG(E2/E1) GROUPIE
GROUPIE
IN ANY OTHER SITUATION, INCLUDING ABSORPTION AND/OR ENERGY GROUPIE
DEPENDENT CROSS SECTIONS, THE SPECTRUM WILL NOT BE 1/E - GROUPIE
ABSORPTION WILL TEND TO DECREASE THE SPECTRUM PROGRESSIVELY GROUPIE
MORE AT LOWER ENERGIES - ENERGY DEPENDENCE OF THE CROSS SECTION GROUPIE
WILL LEAD TO SELF-SHIELDING. GROUPIE
GROUPIE
HERE WE WILL NOT ATTEMPT TO PERFORM A DETAILED SPECTRUM GROUPIE
CALCULATION TO ACCOUNT FOR ABSORPTION. GROUPIE
GROUPIE
HOWEVER, WE WILL EXTEND THE DEFINITION OF THE RESONANCE INTEGRAL GROUPIE
TO ACCOUNT FOR SELF-SHIELDING EFFECTS BY ALLOWING FOR INCLUSION GROUPIE
OF SELF-SHIELDING EFFECTS IN THE DEFINITION OF GROUP AVERAGES GROUPIE
AND THEN DEFINING THE RESONANCE INTEGRAL AS, GROUPIE
GROUPIE
RI = AVERAGE* LOG(E2/E1) GROUPIE
GROUPIE
IN ORDER TO CALCULATE RESONANCE INTEGRALS YOU MUST FOLLOW THESE GROUPIE
STEPS, GROUPIE
GROUPIE
1) SELECT A 1/E SPECTRUM - ON FIRST LINE OF INPUT PARAMETERS. GROUPIE
2) SELECT THE ENERGY BOUNDARIES - NORMALLY ONLY 1 GROUP FROM GROUPIE
0.5 EV UP TO 20 MEV - HOWEVER, YOU ARE FREE TO SELECT ANY GROUPIE
ENERGY RANGE THAT YOU WISH - YOU MAY EVEN SELECT MORE THAN GROUPIE
1 GROUP MERELY BY SPECIFYING MORE THAN 1 GROUP AS INPUT - GROUPIE
THIS CAN BE USED TO DEFINE THE CONTRIBUTIONS TO THE RESONANCE GROUPIE
INTEGRAL FROM INDIVIDUAL ENERGY RANGES. GROUPIE
3) SELECT THIS OPTION FOR THE UNSHIELDED AND/OR SHIELDED OUTPUT GROUPIE
LISTING - ON THE SECOND LINE OF INPUT PARAMETERS. GROUPIE
GROUPIE
WHEN THIS OPTION IS USED THE PROGRAM WILL CALCULATE GROUP AVERAGEDGROUPIE
CROSS SECTIONS - AS DEFINED ABOVE - PRIOR TO OUTPUT THE RESULTS GROUPIE
WILL MERELY BE MULTIPLIED BY THE WIDTH OF THE GROUP ASSUMING YOU GROUPIE
HAVE SELECTED A 1/E SPECTRUM - THERE IS NO CHECK ON THIS - THE GROUPIE
PROGRAM MERELY MULTIPLIES THE GROUP AVERAGED CROSS SECTIONS BY, GROUPIE
GROUPIE
LOG(E2/E1) - WHERE E2 AND E1 ARE THE GROUP ENERGY BOUNDARIES. GROUPIE
GROUPIE
WARNING - IT IS UP TO YOU TO INSURE THAT YOU FOLLOW EXACTLY THE GROUPIE
STEPS OUTLINED ABOVE IF YOU WISH TO OBTAIN MEANINGFUL GROUPIE
RESULTS. GROUPIE
GROUPIE
NOTE - OUTPUT IN THE ENDF/B FORMAT IS ALWAYS GROUP AVERAGED CROSS GROUPIE
SECTIONS, REGARDLESS OF WHETHER YOU ASK FOR AVERAGED CROSS GROUPIE
SECTIONS OR RESONANCE INTEGRALS - THIS IS BECAUSE DATA IN GROUPIE
THE ENDF/B FORMAT IS EXPLICITLY DEFINED TO BE CROSS GROUPIE
SECTIONS. GROUPIE
GROUPIE
RESONANCE INTEGRAL OUTPUT CAN ONLY BE OBTAINED IN THE GROUPIE
LISTING FORMATS. GROUPIE
GROUPIE
MINIMUM TOTAL CROSS SECTION TREATMENT GROUPIE
------------------------------------- GROUPIE
SINCE THE BONDARENKO SELF-SHIELDING DEPENDS ON 1/TOTAL CROSS GROUPIE
SECTION, THE ALGORITHM WILL BECOME NUMERICALLY UNSTABLE IF THE GROUPIE
TOTAL CROSS SECTION IS NEGATIVE (AS OCCURS IN MANY ENDF/B GROUPIE
EVALUATIONS). IF THE TOTAL IS LESS THAN SOME MINIMUM ALLOWABLE GROUPIE
VALUE (DEFINE BY OKMIN, PRESENTLY 1 MILLI-BARN) AN ERROR MESSAGE GROUPIE
WILL BE PRINTED AND FOR THE SELF-SHIELDING CALCULATION ALL ENERGY GROUPIE
INTERVALS IN WHICH THE TOTAL IS LESS THAN THE MINIMUM WILL BE GROUPIE
IGNORED. GROUPIE
GROUPIE
NOTE, FOR THE UNSHIELDED CALCULATIONS ALL CROSS SECTIONS WILL BE GROUPIE
CONSIDERED WHETHER THEY ARE POSITIVE OR NEGATIVE. THEREFORE IF GROUPIE
THE TOTAL CROSS SECTION IS NEGATIVE OR LESS THAN THE MINIMUM GROUPIE
VALUE THERE MAY BE AN INCONSISTENCY BETWEEN THE UNSHIELDED AND GROUPIE
THE SELF-SHIELDED CROSS SECTIONS. IF THE TOTAL CROSS SECTION IS GROUPIE
NEGATIVE AND SELF-SHIELDED CROSS SECTIONS ARE CALCULATED THE GROUPIE
PROGRAM WILL PRINT AN ERROR MESSAGE INDICATING THAT THE SELF- GROUPIE
SHIELDED RESULTS ARE UNRELIABLE AND SHOULD NOT BE USED. THEREFORE GROUPIE
IN THIS CASE THE PROGRAM WILL NOT ATTEMPT TO MODIFY THE UNSHIELDEDGROUPIE
RESULTS TO ELIMINATE THE EFFECT OF NEGATIVE CROSS SECTIONS, SINCE GROUPIE
THE UNSHIELDED RESULTS ARE THE ONLY ONES WHICH TRULY REFLECT THE GROUPIE
ACTUAL INPUT. GROUPIE
GROUPIE
RESOLVED RESONANCE REGION GROUPIE
------------------------- GROUPIE
IN THE RESOLVED RESONANCE REGION (ACTUALLY EVERYWHERE BUT IN THE GROUPIE
UNRESOLVED RESONANCE REGION) THE CROSS SECTIONS OUTPUT BY LINEAR- GROUPIE
RECENT-SIGMA1 WILL BE ACTUAL ENERGY DEPENDENT CROSS SECTIONS AND GROUPIE
THE CALCULATIONS BY THIS PROGRAM WILL YIELD ACTUAL SHIELDED AND GROUPIE
UNSHIELDED CROSS SECTIONS. GROUPIE
GROUPIE
UNRESOLVED RESONANCE REGION GROUPIE
--------------------------- GROUPIE
IN THE UNRESOLVED RESONANCE REGION PROGRAM RECENT USES THE GROUPIE
UNRESOLVED RESONANCE PARAMETERS TO CALCULATE INFINITELY DILUTE GROUPIE
AVERAGE CROSS SECTIONS. THIS PROGRAM WILL MERELY READ THIS GROUPIE
INFINITELY DILUTE DATA AS IF IT WERE ENERGY DEPENDENT DATA AND GROUPIE
GROUP AVERAGE IT. AS SUCH THIS PROGRAM WILL PRODUCE THE CORRECT GROUPIE
UNSHIELDED CROSS SECTION IN THE UNRESOLVED RESONANCE REGION, BUT GROUPIE
IT WILL NOT PRODUCE THE CORRECT SELF-SHIELDING EFFECTS. GROUPIE
GROUPIE
ACCURACY OF RESULTS GROUPIE
------------------- GROUPIE
ALL INTEGRALS ARE PERFORMED ANALYTICALLY. THEREFORE NO ERROR IS GROUPIE
INTRODUCED DUE TO THE USE OF TRAPAZOIDAL OR OTHER INTEGRATION GROUPIE
SCHEME. THE TOTAL ERROR THAT CAN BE ASSIGNED TO THE RESULTING GROUPIE
AVERAGES IS JUST THAT DUE TO THE ERROR IN THE CROSS SECTIONS GROUPIE
AND ENERGY DEPENDENT WEIGHTING SPECTRUM. GENERALLY SINCE THE GROUPIE
THE ENERGY DEPENDENT WEIGHTING SPECTRUM APPEARS IN BOTH THE GROUPIE
NUMERATOR AND THE DENOMINATOR THE AVERAGES RAPIDLY BECOME GROUPIE
INSENSITIVE TO THE WEIGHTING SPECTRUM AS MORE GROUPS ARE USED. GROUPIE
SINCE THE WEIGHTING SPECTRUM IS LOADED IN THE PAGING SYSTEM THE GROUPIE
USER CAN DESCRIBE THE SPECTRUM TO ANY REQUIRED ACCURACY USING GROUPIE
ANY NUMBER OF ENERGY VS. SPECTRUM PAIRS. GROUPIE
GROUPIE
MULTI-BAND PARAMETERS GROUPIE
--------------------- GROUPIE
MULTI-BAND PARAMETERS ARE CALCULATED FOR THE TOTAL, ELASTIC, GROUPIE
CAPTURE AND FISSION REACTIONS. WITH THE NUMBER OF GROUPS THAT GROUPIE
ARE NORMALLY USED (SEE BUILT IN GROUP STRUCTURES) ALL OTHER GROUPIE
REACTIONS RESULT IN A NEGLIGABLE AMOUNT OF SELF-SHIELDING. AS GROUPIE
SUCH THEIR EQUIVALENT BAND CROSS SECTION WILL MERELY BE THEIR GROUPIE
UNSHIELDED VALUE WITHIN EACH BAND. GROUPIE
GROUPIE
FOR ANY GIVEN EVALUATION, WITHIN ANY GIVEN GROUP THIS PROGRAM GROUPIE
WILL GENERATE THE MINIMUM NUMBER OF BANDS REQUIRED WITHIN THAT GROUPIE
GROUP. AS OUTPUT TO THE COMPUTER READABLE DISK FILE THE BAND GROUPIE
PARAMETERS FOR EACH EVALUATION WILL BE FORMATTED TO HAVE THE GROUPIE
SAME NUMBER OF BANDS IN ALL GROUPS (WITH ZERO WEIGHT FOR SOME GROUPIE
BANDS WITHIN ANY GROUP). THE USER MAY DECIDE TO HAVE OUTPUT GROUPIE
EITHER WITH THE MINIMUM NUMBER OF BANDS REQUIRED FOR EACH GROUPIE
EVALUATION (E.G. 2 BANDS FOR HYDROGEN AND 4 BANDS FOR U-233) OR GROUPIE
THE SAME NUMBER OF BANDS FOR ALL EVALUATIONS (E.G. 4 BANDS FOR GROUPIE
BOTH HYDROGEN AND U-233). GROUPIE
GROUPIE
FOR 2 OR FEWER BANDS THE PROGRAM USES AN ANALYTIC EXPRESSION GROUPIE
TO DEFINE ALL MULTI-BAND PARAMETERS. FOR MORE THAN 2 BANDS THE GROUPIE
PROGRAM PERFORMS A NON-LINEAR FIT TO SELECT THE MULTI-BAND GROUPIE
PARAMETERS THAT MINIMIZE THE MAXIMUM FRACTIONAL ERROR AT ANY GROUPIE
POINT ALONG THE ENTIRE SELF-SHIELDING CURVE. THE NUMBER OF BANDS GROUPIE
REQUIRED WITHIN ANY GIVEN GROUP IS DEFINED BY INSURING THAT THE GROUPIE
MULTI-BAND PARAMETERS CAN BE USED TO ACCURATELY DEFINE SELF- GROUPIE
SHIELDED CROSS SECTIONS ALONG THE ENTIRE SELF-SHIELDING CURVE GROUPIE
FROM SIGMA0 = 0 TO INFINITY. THE USER MAY DEFINE THE ACCURACY GROUPIE
REQUIRED. GROUPIE
GROUPIE
ENDF/B FORMATTED UNSHIELDED AVERAGES GROUPIE
------------------------------------ GROUPIE
UNSHIELDED MULTI-GROUP AVERAGED CROSS SECTIONS FOR ALL REACTIONS GROUPIE
MAY BE OBTAINED IN THE ENDF/B FORTRAN IN EITHER HISTOGRAM GROUPIE
(INTERPOLATION LAW 1) OR LINEARLY INTERPOLABLE (INTERPOLATION GROUPIE
LAW 2) FORM. SEE INPUT BELOW FOR DETAILS. GROUPIE
GROUPIE
MIXTURES OF MATERIALS AND RESONANCE OVERLAP GROUPIE
------------------------------------------- GROUPIE
THE SELF-SHIELDED CROSS SECTIONS FOR THE INDIVIDUAL CONSTITUENTS GROUPIE
OF ANY MIXTURE CAN BE CALCULATED BY THIS PROGRAM BY REALIZING THATGROUPIE
THIS PROGRAM ESSENTIALLY ONLY USES THE TOTAL CROSS SECTION AS A GROUPIE
WEIGHTING FUNCTION TO ACCOUNT FOR SELF-SHIELDING EFFECTS. FOR A GROUPIE
MIXTURE IT IS THEREFORE ONLY NECESSARY TO USE THE TOTAL CROSS GROUPIE
SECTION FOR THE MIXTURE IN PLACE OF THE ACTUAL TOTAL CROSS SECTIONGROUPIE
FOR EACH CONSTITUENT AND TO RUN THIS PROGRAM. THIS CAN BE DONE BY GROUPIE
FIRST RUNNING PROGRAM MIXER TO CALCULATE THE ENERGY DEPENDENT GROUPIE
TOTAL CROSS SECTION FOR ANY COMPOSITE MIXTURE. NEXT, SUBSTITUTE GROUPIE
THIS COMPOSITE TOTAL CROSS SECTION FOR THE ACTUAL TOTAL CROSS GROUPIE
SECTION OF EACH CONSTITUENT (IN EACH ENDF/B FORMATTED EVALUATION).GROUPIE
FINALLY, RUN THIS PROGRAM TO CALCULATE THE SELF-SHIELDED CROSS GROUPIE
SECTION FOR EACH CONSTITUENT, PROPERLY ACCOUNTING FOR RESONANCE GROUPIE
OVERLAP BETWEEN THE RESONANCES OF ALL OF THE CONSTITUENTS OF THE GROUPIE
MIXTURE. DURING THE SAME RUN THESE SELF-SHIELDED CROSS SECTIONS GROUPIE
CAN IN TURN BE USED TO CALCULATE FULLY CORRELATED MULT-BAND GROUPIE
GROUPIE
MULTI-BAND PARAMETER OUTPUT FORMAT GROUPIE

FOR VERSIONS 92-2 AND LATER VERSIONS THE MULTI-BAND PARAMETERS GROUPIE
ARE OUTPUT IN A SIMPLE CHARACTER FORMAT, THAT CAN BE TRANSFERRED GROUPIE
