I Response to Inspection Report 93-18/18 Operational Cycle Monitoring Program Upgrade Schedule l '. Revise the routine test procedure that maintains a cumulative :

record of Reactor Pressure Vessel temperature and pressure t cycles to include additional events and new " maximum allowable" occurrences. This revision will be completed by December 15, 1993. .;

I 2. Develop a concise and consistent methodology for counting of cycles. This methodology will be completed by March 31, 1994.

,

3. Det. ermine the past data that is required and initiate retrieval of this data from the archive storage facility. .

This action will be completed by April 30, 1994, 4. Perform a preliminary review to verify the , adequacy of the ;

methodology developed for counting of cycles and the content '

of the routine test procedure. Additionally, ensure that ;

there is sufficient data obtained from the archives to effectively count cycles and determine the number of cycles-expended. Based on the review of this preliminary - data, -

additional records may need to be retrieved or procedures and L

'

methodologies may require revision. This preliminary review will be completed by May 31, 1994. '

5. Review and evaluate the data obtained to determine the total

'

number of cyclic transients. This action will be completed by December 31, 1994.  ;

6. Prepare a table of the cycles expended to date and compare with each transient listed in the Updated Final Safety Analysis Report, Table 4.2.4. Evaluate the percentage of i

'

total component life that has been expended. This evaluation will be completed by December 31, 1994.
