Subject:
PVNGS Natural Circulation Cooldown Testing.
Dear Mr. Knighton:
ANPP held a meeting with the NRC Staff on June 27,.1985 to discuss the PVNGS Unit 1 Natural Circulation Testing Program.
,The NRC Staff raised several questions during this meeting which were discussed in the telecon of Reference (3).
The purpose of this submittal is to formally document the actions that ANPP has taken to resolve the NRC concerns.
ANPP has revised the Natural Circulation Cooldown Test Procedure which has been submitted previously by Reference (1).
The following changes have been made to the procedure.
It should be noted that these changes were discussed during the telecon of Reference (3).
iv)
The procedure has been modified to assume a single failure (i.e., failure of one of the emergency diesel generators).
Only one train 'of safety related equipment will be used during the 'test.
The letdown portion of the Chemical and Volume Control System will be secured during the portion of the depressurization where the auxiliary pressurizer spray system is utilized.
The pressurizer heaters will not be utilized during the test.
However, the pressurizer heaters will be available for use during the test.
Only two of, the three charging pumps will be used during the test.
However, the third charging pump will be available for use during the test.
ANPP will demonstrate by testing the capability to cooldown the plant under natu-ral circulation conditions from hot standby conditions to cold shutdown conditions.

'Natural Circulation Testing Program
The demonstration will be conducted by one of'he following two methods:
A single test that conducts a Natural Circulation Cooldown from hot standby to cold shutdown conditions.
Two separate tests:
The first test will perform a Natural Circulation Cooldown from hot standby to shutdown cooling initiation conditions.
The second test will demonstrate the capability to cooldown the plant from shutdown cooling initiation conditions to cold shutdown.
Additionally, data from the Natural Circulation Cooldown Test will be used to verify the effectiveness of the auxiliary pressurizer spray system for the Steam Generator Tube Rupture Event.
If you have any additional questions on this matter, please contact Mr. N. F. Quinn of my staff.
Very truly ou CRA'A E. E.
