Subject:

Limerick Generating Station, Unit 1 and Common First Ten Year Interval Inservice Inspection (ISI) Program Submittal of Relief Requests and Revised Edition of the of the Program Plan Document Gentlemen:

By letter dated October 23, 1985, we submitted the Limerick Generating Station (LGS), Unit 1 and Common, First Ten Year Interval Inservice Inspection (ISI) Program (i.e., Specification 8031-P-500) and Augmented Inservice Inspection (AISI) Program (i.e., Specification 8031-P-501). The NRC reviewed and subsequently approved the LGS, Unit 1 and Common, First Ten Year Interval ISI and AISI Programs as documented in its letter dated March 4, 1988.

The LGS Unit 1 and Ccmmon, First Ten Year Interval ISI and AISI Programs have been upgraded to satisfy the requirements specified in the 1986 Edition of the American Society of Mechanical Engineers (ASME),

Boiler and Pressure Vessel (B&PV) Code Section XI, for the remaining portion of the inspection interval (i.e., after completion of the third refueling outage). This upgrade was strictly voluntary and was initiated

'to allow Unit 1 to utilize the same Edition of the ASME Section XI Code as that required for Unit 2. In addition, other revisions to the Unit 1 Program were made in order to reflect organizational changes, plant modifications, and to improve document format. Futhermore, the LGS Unit 1 and Common ISI Program is now similar in format to the Unit 2 program which was submitted by our letter dated February 26, 1990.

-As a result of upgrading the Programs, Specifications 8031-P-500 and 8031-P-501 have been superseded by Specification NE-42. Enclosure 1 of this letter contains an " Uncontrolled" copy of Volume 1 of the Program document which is the latest edition of the LGS, Unit 1 and Common, First Ten Year Interval ISI Program (i.e., Specification NE-42, I ne, ~ .

-Revision 1). This document-is being submitted for your information and use. Attachment 1-of the enclosed Specification NE-42, Revision 1, contains a report which identifies the extent of examinations which were completed during the first three (3) refueling outages at Unit 1, in accordance with the 1980 Edition through Winter 1981 Addenda of the ASME Section XI Code requirements. This report also documents the logic used to determine the scope of examinations needed to be performed during the remainder of the first ten year inspection interval-in order to satisfy the requirements of the 1986 Edition of ASME Section XI Code for Unit 1.

In addition, enclosed for your review and approval are five (5) new relief requests and two (2) revised relief. requests for the LGS Unit 1 and Common, First Ten Year Interval ISI Program. These relief requests

.are being submitted in accordance with 10 CPR 50.55a(g) (5) and are provided in Enclosure 2 of this letter. An ISI Program relief request summary identifying and describing the new and revised relief requests is also contained in Enclosure 2. These relief requests have boon included in the enclosed ISI Program document; however, their implementation is pending NRC approval.

As a result.of implementing Specification NE-42, the format for the ISI Program relief requests has been revised. Since the relief request. format has changed, no revision markings are identified in the margin of the revised relief requests. However, a description of the proposed changes is provided in the enclosed summary. No other ISI

~ Program relief requests have been revised, except in format.

Iffyou have any questions or require additional-information, please do not hesitate to contact us.  ;

in the absence of any other required maintenance on either of the Reactor _ Recirculation A pumps, the hardships associated with pump disauembly, solely for the purpose of sisual

-The disassembly of a teactor recirculation pump at 1 GS I constitutes a maintenance task of major proportions incasured both in teams of manhours and associated personnel exposure. .

Plant experience wah the pump casing materialin this application is favorable. The adEtional assurance of structural integrity afforded by visual examination is far outweighed .

by the cost and potential hantds presented to facilitate the inspection, in comideration of -

this situation, the 1989 !!dition of Section XI requires a VTO examination only if the pump is ditassembled for maintenance, repair or volumetrie examination.-

The Code Case (s) discus 3ed in 111 ab,vc irpersent technically acceptable alternative rules to ASMB Section XI Code rules. The fact that the Code Case (s)l. ave not been endorsed in the llegulatory Guide in no way detracts from their technical adequacy since the major reason for their omission is the timing of their publication with respect to the most recent ,

. revision of the Itegulatory Guide. That is, the subject Code Case (s) are relatively accent and

, it is expected that these Code Case (s) will be accepted in a subsequent revision of the llegulatory Fulde. [

Adoption of these attemative rules provides an acceptable level of qua'.ity and safety and does not ccmpromise the adequacy of the I.GS I 151 Program in meeting the intent of ASME Section XI. .

Relief is requested from the examination requirements of Articles IWF 1000, IWF 2000, p (excluding IWF 2520), and Table IWF-25001 and the insenice testing requirements of Article IWF 5000 due to the redundancy of these examinationitest requirements to 1,GS-l Technical Specification requirements.
