Dear Mr. Butler:
This will confirm the information provided to the NRC Staff in the reference telecons. relating to the required alert levels for the Limerick #1 Loose Parts Monitoring System (LPMS) and the Regulatory Guide 1.133 report due within 90 days of the completion of the startup test program.
The startup testing and analysis of the test data has established alarm levels for 6 of the 8 channels. Channels 5 and 6 have a predominate single sine wave which is suspected to be an electrical contamination or' pickup within the containment building; therefore, we cannot determine the correct alarm level. The requested delay in submitting the report is to allow investigation and reparation of this problem during the ongoing Unit #1 surveillance outage.
During the outage we will:
1.
Inspect all LPMS equipment.
2.
Replace equipment as required.
3.
Perform calibrations.
4.
B&W will analyze the tape recording made during the unit shutdown and present to PEC7 their recommendations.

- During the unit startup, recordings of all 8 channels will be made as the unit reaches full power. The data will be analyzed by B&W and a report submitted to PECo. We propose that, following evaluation of the B&W report by PECo, the Reg. Guide 1.133 alert level report will be submitted to the NRC within seven weeks after the Unit #1 outage completion which is scheduled for June 15, 1986.
The unit will be operating after the outage with 6 of 8 channels with correct alarm levels. During this time, while channels 5 and 6 are being analyzed, we will have sufficient monitoring with the remaining 6 channels. Channels 5 and 6 will be set with a higher alarm level and will be checked with a spectrum analyzer once a week until the alarm level setting is resolved. This will ensure that all channels are being monitored sufficiently.
Very truly yours,
