" Position on NRC Regulatory Guide 1.97, Revision 3 Requirements for Post-Accident Neutron Monitoring System" (GeneralElectricReportNED031558), June 13,1988.

Reference 2 requested that the staff expedite its review of Reference 1.

Reference 1 submitted the BWR Owners' Group (BWROG) Licensing Topical Report (LTR) for staff review and approval.

The LTR proposed functional criteria for post-accident neutron flux monitoring as an alternative to the Category 1 recommendations specified in Regulatory Guide.(R.G.) 1.97.

Based onL our review, the staff concludes that a Category 1 designation, and associated lower range for neutron flux monitoring equipment is appropriate.

Therefore, the proposed LTR NED0-31558 is unacceptable and the neutron flux monitoring equipment must be environmentally qualified to comply with 10CFR50.49.

If you have any que'stions regarding the above information, please contact Barry Marcus, of sy staff on 49-20776.

Sincerely.
