" Power Oscillations in Boiling Water Reactors (BWRs)"
REFERENCE:
Philadelphia Electric Company letter to the NRC,
' dated September 15, 1988, responding to NRC 8ulletin No. 88-07
Dear Sir:
NRC Bulletin No. 88-07, Supplement 1:
" Power Oscillations in Boiling Water Reactors (BWRs)," dated December 30, 1988, was received by the Philadelphia Electric Company (PECo) on January 4, 1989.
This Bulletin requested that all BWR licensees implement the General Electric (GE) interim stability recommendations described in an attachment to the Bulletin supplement within 30 days of receipt of the supplement.
NRC Bulletin 88-07, Supplement 1, also required that holders of Operating Licenses
.(OLs) advise the NRC within 60 days of receipt of the supplement whether the requested actions have been completed and implemented, for Construction Permit (CP) holders, the supplement *equires that the NRC be advised that the requested actions have been completed and implemented prior to fuel loading. This letter provides PECo's response for the L?merick Generating Station (LGS), Units 1 and 2, and the Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3.
This letter also provides clarification of certain information contained in the referenced letter.
The GE interim stability recommendations were completed by January 31, 1989 and implemented for LGS Unit 1.
Since the applicable LGS Unit 1 procedures and limitations will be used for the operation of LGS Unit 2, we consider that the GE recommendations have also been completed and implemented for LGS Unit 2.
At PBAPS, l
changes to the principal procedures affected by the GE recommendations were completed by February 3, 1989. A review of additional pertinent procedures is continuing, and any required changes will be completed and implemented prior to restart of PBAPS Unit

The requirement for manual reactor trip under all operating conditions when two recirculatiori pumps trip is not necessary at any of the units since LGS and PBAPS have a flow biased neutron flux trip.
LGS Unit 1 and PBAPS Units 2 and 3 use NRC approved GE fuel.
LGS Unit 2 l
will use GE fuel once the OL is granted. Therefore, the stability boundaries shown in an attachment to the supplement do not need to be reevaluated and justified.
l Further, we have ensured that the procedures and training provided to LGS and PBAPS operators are not ambiguous with respect to permissible conditions for entry into certain operating regions.
The following are clarifications of the information provided in our response to NRC Bulletin No. 88-07 (referenced letter).
o In our September 15, 1988 response to Item #1, we stated that all LGS Reactor Operators and Shift Technical Advisors (STAS) were briefed on the event described in NRC Bulletin No. 88-07 by June 29, 1988.
In fact, some operators and/or STAS were on vacation at that time, but were briefed on this issue upon their return to duty.
o In our September 15, 1988 response to Item #2, we stated that PBAPS operators would receive training on the revisions made to the Recirculation Pump Trip procedure during the August 8, 1988 to September 30, 1988 requalification training cycle.
Extensive use of the plant simulator prevented completion of all make-up sessions until February 3, 1989.
This response is being submitted one day late because of delays in preparation. We regret any inconvenience this may have caused.
If you have any further questions or require additional information, please do not hesitate to contact us.
Very truly yours, bhb Attachment cc:
