TOI Diesel Generator Owners Group The main topic of the subject meeting was a discussion of the PNL Eeport

~

on the Owners' Group Program Plan. This report is attached for yoLr informa ti on.

The major point of contgntion with the PNL Report is in the area of endurance testing to 10' cycles (approximately 750 hrs.). This endurance testing would be required for lead engines at high power levels.

Even though we discussed two components (AE Piston and Crankshaft) in detail, the report implies all components are required to undergo the, endurance, test.

One of the key arguments we made was that the loading requirements of the engine is much less than the rated load. The NRC was very receptive to

(..

this argument and requested mo're information regarding site specific diesel engir.e loading requirements.

Attached to this letter is a LILCO submittal which discusses loading,

requirements for SNPS diesels.

In general, FSAR tables exist;for each However,dery plant similar to the' table attached to the LILC0 submittal.1 Also',

this table has proven to be ultra-conservative in many cases.

little credit is taken for operator action to reduce. engine: loads af ter

Our plan is to develop curves for each plant similar to the.one for SN)S (attached). Thus, the following information is needed for e'sch utility. l

Identify the transient / accident.

Identify the engine (Train A or 8) f 3.

All load decreases due:to" sequencing of loads or operator action 3
