(a) Construction Permits CPPR-135 and CPPR-136, Docket Numbers 50-443 and 50-444 (b) PSNI{ Letter SBN-241, dated March 23, 1982, " Revised Regaponses: 430 Series RAIs", J. DeVincentis to F. J. Miraglia

Subject:

Revised FSAR Tables 8.3-1 and 8.3-2, Diesel Loading

Dear Sir:

Our response to RAI 430.66 [ Reference (b)] committed to provide an automatic trip on diesel generator start of the prelube/ filter pump and the rocker arm prelube pump. Based on our further review and evaluation, these diesel generator auxiliaries will not be automatically tripped on diesel generator start for the following reasons:

1.

Per manufacturer's instructions, the normal operating mode for the prelube/ filter pump is to run continuously to filter the oil, while the diesel generator is operating. Therefore, this pump will not be tripped on diesel generator start. FSAR Tables 8.3-1 and 8.3-2 will be revised as they have been annotated in the Attachment to include this purep as a continuous load.

2.

Per manufacturer's inatttactions, the control switch for the rocker arm prelube pump is spring return to off. When the operator releases the switch on diesel generator start, the pump will stop.

Therefore, there is no need to provide an automatic trip on diesel generator start. This pump will not appear in FSAR Tables 8.3-1 and i

8.3-2.

The attached revisions to FSAR Tables 8.3-1 and 8.3-2 will be included in the next OL Application Amendment.
