SUBJECT:
WAIVER OF CRGR REVIEW FOR WCAP-13524, AND WCAP-13524.
REVISION 1, " APOLLO-A ONE DIMENSIONAL NEUTRON DIFFUSION THEORY PROGRAM"
REFERENCES:
Memorandum from E. L. Jordan to T. E. Murley "CRGR Consideration of Topical Reports", September 29, 1989.
Attached is the safety evaluation report (SER) prepared by the Division of )
System Safety and Analysis in which the staff accepts for referencing i WCAP-13524 and WCAP-13524. Revision 1. In accordance with the suggested l revised procedures referenced above, the staff proposes that review by the '
Committee to Review Generic Requirements (CRGR) be waived.
WCAP-13524 and WCAP-13524 Revision 1. describe the APOLLO computer code and the first revision to the APOLLO computer code. APOLLO is a one-dimensional, two-group diffusion code that was evolved ' rom the NRC ap] roved computer code
" PANDA". APOLLO is used for nuclear design analyses whica do not require three-dimensional methods. The calculational accuracy of the APOLLO code for predicting the reactivity and axial power shapes is comparable to the three dimensional code " Advanced Nodal Code" (ANC).
According to its charter CRGR should review each staff approval of topical reports. However, the staff believes that CRGR review is not necessary because WCAP-13524 does not present a new staff position. If you agree that a CRGR review is not necessary, please so indicate by signing below. Otherwise.
the staff will prepare an appropriate CRGR package.
