Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS I AND 2 PROPOSED TECHNICAL SPECIFICATIONS CHANGES INDIVIDUAL ROD POSITION INDICATION SYSTEM License Nos. DPR-32 DPR-37 Pursuant to 10 CFR 50.90, Virginia Electric and Power Company requests an amendment, in the form of changes to the Technical Specifications, to Operating License Nos.
DPR-32 and DPR-37 for Surry Unit Nos.
1 and 2, respectively.
The proposed Technical Specifi cat i ans changes wi 11 revise the requirements governing the operability of the Individual Rod Position Indicating (IRPI)
System.
Surry has experienced operational difficulties with the IRPI system due to system nonlinearities and both transient and steady state temperature sensitivities.
The basic thrust of the proposed changes is to shift the emphasis from the IRPI system to the demand position indicating system (the step counters) for rod group position information during shutdown and certain transient operational modes such as reactor startup.
For those conditions where confirmatory information demonstrating rod motion on demand is important, the IRPI system will still be available to provide this information.
The proposed changes are presented in Attachment
- 1.
The technical justification and safety evaluation of the proposed changes is provided in.
This request has been reviewed and approved by the Station Nuclear Safety and Operating Committee and by the Safety Evaluation and Control Staff.
It has been determined that this request does not involve an unreviewed safety question as defined in 10 CFR 50.59 or a significant hazards consideration as defined in 10 CFR 50.92.
The basis for the determination that no significant hazards consideration is involved is presented in Attachment 3.
I.

e An application fee of $150 is enclosed in accordance with 10 CFR 170.12.
Sincerely yours,
