Reference:

NUREG-0991 File: GOVT l-1 (NRC)

Dear Mr. Schwencer:

Confirmatory issue #1 of the reference requires Philadelphia Electric to revise FSAR Tables 3.2-1 and 3.2-2. Attached are draft FSAR pages that will be included in FSAR Revision 34 which will be submitted in July. The attached pages provide additional information describing Limerick compliance with Regu2 story Guide 1.26, Revision 3, and the codes and standards used in construction.

Providing this information satisfies the SER requirement to enable closure of confirmatory issue #1.

Sincerely, y

feedwater and RCIC line taps (outside primary containment is classified Group B. The RWCU tap into the feedwater line inside primary containment is classified Group B up to the outboard containment isolation valve (41-1016). Valve 41-1016 and piping up to the tap into the feedwater line is classified Group A.

(17)The high pressure coolant injection (HPCI) and reactor core isolation cooling (RCIC) turbines do not fall within the applicable design codes. To ensure that the turbine is fabricated to the standards commensurate with their safety and performance requirements, General Electric has established specific design requirements for this component in their specification.

(18)Certain major liquid, solid, and gaseous radwaste system components were designed, fabricated, procured, installed, and tested to the requirements of ASME Section III, (Jca95A 0ivisi;r 3, prior to May 1978. After May 1978, system design, fabrication, materials, procurement, installation, and testing are, at a minimum, in accordance with quality group D'and the intent of Regulatory Guide 1.143, Rev. 1, subject to the following clarif.' cations and exceptions:

a. Certain atmospheric tanks are welded to API /AWS standards in lieu of ASME Section IX.

b. Curbs or elevated _ thresholds are not provided for indoor tanks because of the watertight integrity of the surrounding structure.

c. Hydrotest pressure is held for 10 minutes, in accordance with ASME Section III, rather than 30 minutes.

d. The cadwaste enclosure is designed in accordance with seismic Category-I criteria (Section 3.8.4). Limerick does not use Regulatory Guide 1.60, as stated in Section 1.8. Alternate methods are discussed in Sections 3.7 and 3.8.

e. Limerick's quality program during construction does not require audits of activities associated with radwaste systems, and items of noncomformance and their-regulation are not always documented.

, f. Cleaning and welding of piping is conducted in

'accordance with the specified piping quality group.

(19)See Section 3.2.2 for discussion of conformance to Regulatory Guide 1.26.

(?) PECo's request to use alternat:ve codes to those required 1.9 10 CFR Part SC.55a for primary pressure boundary components was sent to the NRC on 7/15/75. The applicable codes, code dates, and addenda are listed in the request letter for the following components which are still included in the Limerick design:

1 Reactor pressure vessel 2' Main steam safety / relief valves 35 Main steam piping (26") from RPV to 2nd isolation valve 4' Main steam line suspension 5' Recirculation pump 6: Recirculation gate valves (motor-operated :

28" suction 28" discharge 7! Recirculation loop piping (28")

8) Recirculation loop suspension

9) RHR valves 20" gate valve

10) Core spray valves 12" check valve (air-operated)

11) Nuclear Class I piping (all except main stear and recirculation)

NRC approval of the request was given on 11/18/75 in a letter from R.C. De Young to E.G. Bauer of PECo.

The applicable code for design, fabrication, and testing of the main steam isolation valves is the ASME Standard Code fo'r Pumps and Valves for Nuclear Power - 1968 Draft including March 197C Addenda.

(3 ; Class D tanks shall be designed, constructed, and tested to meet the intent of API Standards 620/650, AWWA Standard D100, or ANSI B96.1 Standa rd for Aluminus Tanks.

(41 For pumps classified Group D and operating above 150 psi or 2120F, ASME Section VIII, Div. 1 shall be used as a guide in ca lcula ting the wall thickness f or pressure retainina parts 'and in sizing the cover bolting. For pumps operating below 150 psi and 21207, manufacturer's s'ta nda rd pump for service intended say be used.

( 5) For pumps classified A, B, or C applicable Subsect ions N B, N C, or ND respectitcly in ASME Boiler and Pressure Vessel Code,Section III shall be used as a guide in calcula ti ng the thickness of p re ss u re retaining portions of the pump and in sizinq cover Dolting.
