DRAFT SUPPLEMENTAL INFORMATION NEEDED RELIEF REQUEST PPL SUSQUEHANNA, LLC ALLEGHENY ELECTRIC COOPERATIVE, INC.
SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 DOCKET NOS. 50-387 AND 50-388 The Nuclear Regulatory Commission (NRC) staff has reviewed the application you submitted by letter dated October 8, 2013, 1 and concluded that the information delineated below is necessary to enable the staff to make an independent assessment regarding the acceptability of the proposed relief request in terms of regulatory requirements and the protection of public health and safety and the environment.
Relief Requests 1RR-03/2RR-03 (Attachments 3 and 9)
The code of record for the Susquehanna fourth ten year IST program is 2004 Edition through the 2006 Addenda of the ASME OM Code. For Relief Requests 2RR-03, it appears that the relief is requested from the paragraph I-1330(a) of the older 1998 Edition of the ASME OM Code, which was the code of record for the third ten-year IST program at Susquehanna.
- 1. The licensee should correct the error and resubmit the relief request from the requirements (I-1320(a)) of 2004 Edition through the 2006 Addenda.
In addition, the licensee states in Section 4, Proposed Alternate Testing, that no additional valves will be tested if the as-found setpoint is below the nameplate setpoint. This appears conflicting with the requirements of paragraph I-1350(c)(1), which states that for each valve tested for which the as found set pressure exceeds the greater of either the +/- tolerance limits of the Owner-established set-pressure of I-1310(e) or +/-3% of valve nameplate set-pressure, two additional valves shall be tested from the same group.
- 2. The licensee should provide justification for not testing additional valves or submit an additional relief request from the requirements of paragraph I-1350(c)(1) if the lower setpoint limits are not met.
Relief Requests 1RR-06/2RR-05 The code of record for the Susquehanna fourth ten year IST program is 2004 Edition of ASME OM Code through 2006 Addenda. For Relief Requests 1RR-06/2RR-05, the relief is requested from the paragraph I-3410(d) of the older 1998 Edition of the ASME OM Code, which was the code of record for the third ten-year IST program at Susquehanna.

In addition, the licensee should note that the requirements have been revised in paragraph I-3410(d).
- 4. The licensee should review the revised requirements of I-3410(d) for testing Class 1 Main Steam Pressure Relief Valves with Auxiliary Actuating Devices, and determine if the request is still necessary.
