Dear Mr. Denton:
NORTH ANNA 2 POWER ESCALATION AND TESTING SCHEDULE In response to a request from Mr. Alex Dromerick of your staff, we are providing the attached schedule for our North Anna Unit 2.
This schedule constitutes our current realistic estimate of major testing that is planned for the time period until Commercial Operation. However, unforeseen equipment problems could delay Commercial Operation beyond the anticipated date of November 15, 1980.
We have endeavored to include in this schedule all major tests and modifications that are presently foreseen.
We intend to utilize, to the extent possible, planned unit trips and outages during this time period to perform tests that require a plant shutdown in order to eliminate unnecessary shutdowns and transients.
It is recognized that with a concerted effort this schedule could be compressed to hasten the declaration of Commercial Operation. However, it is our desire to escalate power at a careful and deliberate pace consistent with the TMI Action Plan, NUREG-0660,Section IV.F, and to insure that expeditious completion of the power ascension test program does not compromise Vepco's commitment to the safe and beneficial utilization of nuclear power.
l l
Very truly yours, B. R. Sylvia Manager - Nuclear Operations and Maintenance l
