RELIEF REQUESTS FROM ASME XI FOR SURRY POWER STATION UNITS 1 AND 2 10 YEAR INSERVICE INSPECTION In our letter dated January 7, 1983 (Serial No. 001) we submitted relief requests for Surry Unit 1 and stated that the submittal would be supplemented with Unit 2 relief requests. Attached are the Surry Unit 2 relief requests.

In addition, some modifications and deletions to Unit l's requests are included. In most cases the Unit 2 request parallels the Unit 1 request with only changes to the valve, line, or mark numbers.

Very truly yours, ll!ldJ::it:

i RELIEF REQUESTS RR-1 The_ same as RR-1 for Unit 1 with corresponding valve, line, or mark number changes.

RR-2 Unnecessary. Delete for both units.

RR-3 The same as RR-3 for Unit 1 with corresponding valve, line, *or mark number changes except as follows (refer to January 7, 1983 submi~tal for format):

le. Class I and II

2. Class I System Hydrostatic Test, IWC 5222 Class II System Hydrostatic Test, IWC 5222 The above changes apply to both Unit 1 and Unit 2.

RR-4 The same as RR-4 for Unit 1 with corresponding valve, line, or mark number changes.

RR-5 The same as RR-5 for Unit 1 with corresponding valve, line, or mark number changes.

RR-6 The same as RR-6 for Unit 1 with corresponding valve, line, or mark number changes.

RR-7 The same as RR-7 for Unit 1 with corresponding valve, line, or mark number changes.

RR-8 The same as RR-8 for Unit 1 with corresponding valve, line, or mark number changes.

RR-9 The same as RR-9 for Unit 1 with corresponding valve, line, or mark number changes.

RR-10 The same as RR-10 for Unit 1 with corresponding valve, line, or mark number changes except as follows (refer to January 7, 1983 submittal for format):

3. The check valve boundary prevents isolation of the adjoining Class I system from the Class II system mentioned. The lack of overpressure protection within the boundary requires a valve Pd (Design Pressure) equal to 2485 psig times 1.25 (T>200° F) for a test pressure of 3106 psig. The test pressure for the adjoining Class I system is the normal operating pressure of 620 to 665 psig by previous relief request (submittal of January 7, 1983). As is evident since isolation is not practical, the Class II test pressure will be far in excess of the test pressure for the Class I system.

e

• 4. As an alternative, it is requested that the Class II components and piping in (la) be examined (VT-2) to the conditions required for the adjacent Class I piping.

These changes apply to both Unit 1 and Unit 2.

RR-11 The same as RR-11 for Unit 1 with corresponding valve, line, or mark number changes.

RR-12 The same as RR-12 for Unit 1 with corresponding valve, line, or mark number changes.

RR-13 Delete for both units.

RR-14 Delete for both units.

RR-15 The same as RR-15 for Unit 1 with corresponding valve, line, or mark number changes.

RR-16 The same as RR-16 for Unit 1 with corresponding valve, line, or mark number changes.
