SUBJECT:

REQUEST FOR ASSISTANCE REGARDING POTENTTAL ENFORCEMEfiT ISSUES ASSOCIATED WITH THE LASALLE 2 OSCILLATIONS EVENT OF MARCH 9, 1938 i

In order to properly corplete the enforcerent determination for sore aspects of the LaSalle oscillations event, Region 11! requests NRR's assistance.

The aspect requiring assistance involves the calculations, analysis and information presented to the NRC by Ccrccchealth Edisen and their vendor which shewed a .6 decay factor for LaSalle Unit 2 indicating a stable core which shculd rot have experiencec cscillations. Our questicos in this area involve wrether ccrplete ar.d correct inferr.ation was prcvided to the NRC, as required, ar.d whether the licensee met their respersibility for a quality techr.ical anelysis.

While ! realize our respective staffs hau held discussiens in this area. I believe a deliberate examination for potential violation is appropriate ar.d er requestir.g NFF.'s assistance because of NRR's expertise and histcrical records. Fctential requirerer.ts thet r.ay have eeen violated include 10 CFR 50 Appe. dix A Crittrict 12, 10 CFR SC Appendix B Criterict III, Design Control, and pcssible false staterent by cmission, f/? W A.
