Notes
* 1. Participants should use their own methods and cross section libraries (but see note 3)
2. For codes not adapted to homogeneous depletion calculations (including WIMSD) the problem may be simulated by a cylindrical fuel zone surrounded by a thin annulus of hydrogen. UIMSD data for such a case takes the following form:

Energy per fission values are:
U235 201.7 MeV or 1.946 1 0 1 ~ o u l e s / m o l e Pu239 210.0 MeV or 2.026 1013 joules/mole
Participants using libaries wit:? different values should adjust the rating (600 M'r\'/te) in proportion to ensare consistency in the number of fissions. .I As a purely fissile fuel burns out, the flux needs to rise rapidly to maintain a specified rating. Participants using a code (such as WIKS) that normalises flux to input rating at specified time intervals, should therefore ensure that those intervals are short enough that changes of flux fro3 one step to the next are 'small'.

AMPX-ORIGEN procedure
The aethod used in the calculations is a combination of va-ious SCALE-3 modules and AMPX codes to perform the burnup fuel analysis.
(A) Neutronic Depletion Analysis to Produce ORIGEN Working Libraries
BONAMI-S and NITAWL-s codes are used to perform resonance self-shielding treatments for nuclides that have the appropriate data on the specified Master neutron cross-section library.
XSDRNPM-S performs flux calculations to produce a region-weighted working library.
COUPLE updates the ORIGEN-S working binary library with data on the XSDRKPN-S ueighted working library.
ORIGEN-S execution is invoked to compute the ti~e-dependent densities of the nuclides.
This method is applied repeatedly to produce burnup dependent working libraries.
(3) Burnup and K-INFINITY Calculations
ORIGEN-S performs the nuclide generation and depletion calculation of both the irradiated reactor fdel and the decay of spent fuel.
The iSASl sequence of SCALE-3 modular code system (NITA~L-BONAMI-XSDRKPP!) calculates the K-infinity.
DATA LIBRARIES
(A) 218 Group ENDF/B4 Naster Library
The 218-group Library was developed for the Nuclear Regulatory Commission utilizing all of the general-purpose files in the ENDF/B-IV compilation.
It has 72 thermal groups and is suitable for criticality safety analysis of thermal systems.
(B) 27-Group AMPX Master Library
A 27-group format with 13 thermal groups was selected as an adequate broad group structure to collapse the 278-group library.
