/M(sarmw } SHOREHAM NUCLEAR POWER STATION L-- - * * ' P.O. BOX 618, NORTH COUNTRY ROAO e WADING RIVER, N.Y.11792 August 26, 1982 SNRC-759 Mr. Ilarold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555 PSI Relief Requests Shoreham Nuclear Power Station - Unit 1 Docket No. 50-322

Dear Mr. Denton:

Attached please find shoreham's relief requests for the Preservice Inspection Program. It must be noted that the PSI Program imple-mentation is about 98% complete to date. If the final completion of this program results in any additional relief requests, they will also be forwarded to you. At present, it does not appear that additional relief will be required.

If you have any questions with respect to this matter, we will be happy to discuss them with you at your earliest convenience.

Very truly yours, Y

s RELIEF REQUEST NO. 1 I. IDENTIFICATION OF COMPONENTS:

Class I, Category J-1, pressure retaining welds in piping. (See Attachment.)

II. CODE REQUIREMENT Paragraph IS-232 of the ASME Code Section XI, 1971 Edition, requires that a volumetric examination of 100% of circumferential and longitudinal pipe welds, excluding.those welds exempt per IS-121, be performed completely (as preservice examination) prior to initial plant startup.

III. RELIEF DESCRIPTION Relief is required from the ASME Secti'on XI examinations noted on the attachment on the basis of partial '-

inaccessibility of the weld and required volume due to plant design.

IV. BASIS FOR RELIEF The basis for requesting relief from ASME Section XI examination requirements is as follows:

1. The structural integrity of the piping pressure boundary was demonstrated during construction by meeting the requirements of the ASME Code Section III.

All welds were inspected in accordance with the appropriate Code requirements, weld techniques and

welders were qualified in accordance with code requirements and materials were purchased and traced;in accordance with the appropriate Code and NRC requirements

, and guidelines. Finally, the pressure boundary was " proof tested" after installation by the application of a 1.25 times the design pressure hydrostatic test.

2. Complete examinations meeting the requirements of'the ASME Code Section XI were performed on welds of similar configurations which utilized the same weld techniques,(

procedures and materials. The inspected welds are subject to the same operating and environmental

t. 4 conditions as the partially' inspected welds. It is, therefore, reasonable to extend the acceptable results on the inspectable welbs to the partially inspectable welds. ,

-3. Ninety percent (90%) or greater coverage of each of,the partially inspectable welds (see attachment) was achieved. Since the'c'onstruction, operating conditions and environmental conditions on the non-inspected portion of the weld are identical to the inspected area, it is reasonable to extend the satisfactory results to the non-inspectec. areas.

RELIEF REQUEST NO. 3 I. IDENTIFICATION OF COMPONENTS:

Augmented inspection on selected pressure retaining welds in Class 2 piping which were inspected to Class 2, Category J-l requirements using applicable PSI Program inspection procedures.

II. CODE REQUIREMENT:

There is no Code requirement applicable to Shoreham for inspection of these welds under the PSI Program. Inspection of these welds are a result of LILCO's intent to perform augmented examinations as described in appendices D-1, D-2, E-1 & E-2 in the PSI Program Plan.

III. GENERAL DESCRIPTION:

Relief is required from the augmented examinations on the basis of partial inaccessibility of the weld and required volume noted on the attachment due to plant design.

L

, ,i.' .,

I V . .. BASIS-FOR RELIEF:

The basis-for: requesting relief from the augmented-examination is as follows:-

~

1. The structural integrity of the piping pressure

~ boundary was demonstrated during construction by meeting the requirements of the.ASME Code Section III.

All welds were inspected in accordance with the appropriate Code requirements,. weld techniques and welders were qualified in accordance with Code require-ments and materials were purchased and traced in accordance with the appropriate Code and NRC require-ments and-guidelines. Finally,.the pressure boundary was " proof tested".aftdr installation by the application of a-l.25 times the design pressure-hydrostatic test.

2. Complete examinat' ions meeting'the requirements of the augmented examination were performed on welds of similar configurations which utilized the same weld techniques, procedures and materials. The-inspected welds are subject to the same operating and environmental conditions as the partially inspected welds. It is, therefore, reasonable to extend the acceptable results on the inspectable welds to the partially inspectable welds.

}

-s 4

? ' .

3. :1L substantial ~ percent cove' rage of each of the partially inspectable welds 1(see attachment) was achieved. Since the construction,foperating conditions and environmen-tal conditions onfthe'non-inspectable portions of the-weld are identical to.the inspected area, the satisfactory results of.the inspected areas can be extended to the non-inspected. area.

. 4. The Edition of the AStiE Code Section XI which is currently applicable for Inservice Inspection actually decreases the volume > required to be inspected,for the i

" break exclusion" weld. Therefore, a larger percentage-of the weld will be inspectable to Code requirements, thus improving Shoreham's conformance.

1

.5. The Edition of'the ASME' Cod'e'Section XI which is s

e s

currently" applicable'for Inservice Inspection does not-require the Class 2 welds listed on the attachment to i

be inspected.- Therefore, for Inservice Inspection, full compliance for these welds will-be achieved.

Class'I, Category A reactor pressure vessel welds.

1 II. CODE REQUIREMENT:

Paragraph'IS-232 of the ASME Section XI, 1981 edition-code. requires.that a volumetric examination of.100% of pressure containing weldscin reactor vessel belt line region be performed completely as a Preservice examination requirement prior-to initial plant'startup.

III. RELIEF DESCRIPTION Reli'ef is required.from the ASME Section XI examination:

requirements'on the basis of partial inaccessibility of the weld-and. required volume due to vessel design. The Purchase Order date for .the : reactor pressure vessel, dated February, 1967,

resulted in vessel design prior to issue of the ASME Section XI

-Code..

-IV. -BASIS FOR RELIEF:-

-The justification ~for' requesting relief from ASME

~

Section XI' examination requirements is as follows:

1. ' The structural integrity of the vessel pressure boundary is'not in question. All of'the affected welds were subject.to examination and testing requirements of ASME Section III.

2. Complete examinations meeting the. requirements of the ASME Code Section XI were performed on welds offsimilar-c configurations which. utilized the same weld. techniques, procedures and materials. The inspected welds are subject to the same. operating and-; environmental conditions as the partially. inspected welds. It is, therefore, reasonable to extend the acceptable results on-the inspectable welds to the partially inspectable welds.

3. A substcntial percent coverage of each of the partially inspectable welds (see attachment) was achieved. Since the construction, operating conditions and environmental conditions on the non-inspectable portions of the weld are identical to the inspected Jarea, the satisfactory results of the inspected areas can be extended to the non-inspected area.
