Docket Nos. 50-413 and 50-414 i
Dear Mr. Denton:
Per the October 6,1986 telephone call between members of your staff and Duke Power employees, please find attached a clarification to our Technical Specification amendment request dated August 4, 1986.
i i
The intent of the proposed change to Table 3.7-1 was to allow e e unit to remain in i
Mode 3 with full system temperature and pressure so that testing of the main steamline code relief valves may be performed. This is to be ensured by setting the Reactor Protective System power range trip setpoints to 2% Reactor power.
If you have any further questions, please advise.
Very truly yours,
- M i
