SUBJECT:
Peach Bottom Atomic Power Station Units 2 and 3 - Second 120-Month Inservice Inspection (ISI). Program
REFERENCE:
(1)
Letter, J. F. Stolz, USNRC, to E. G. Bauer, Jr., PECo, dated October 29, 1984 (2)
Letter, S. L. Daltroff, PECo, to J.
F. Stolz, USNRC, dated' December 21, 1984
Dear Mr. Stolz:
This letter is submitted as a follow-up to the Reference (2) letter in response to requests by the NRC for additional information regarding the second 120-month ISI program for Peach Bottom Units 2 and 3.
The requests for additional information in the Reference (1) letter, which we committed to respond to at this time, are as restated below along with our response.
REQUEST 3.
Section 2.2.2 of the Program (p 2-5)
This section lists three areas of Class 1 piping in which it may be impossible to obtain complete volumetric examinations on some welds.
These areas are described below:
8502190051 850131 h0 PDR ADOCK 05000277
\\
0 PDR I)I e
Mr. John F. Stolz January 31,.1985 Page.2 a.
Areas within the containment penetrations, b.
Cast fittings and structures that are not amenable to UT examination or in a system that cannot be drained without draining the RPV, and c.
Any weld that,.during the preservice examination (PSI), was found unsuitable for UT examination (and continuous evaluation indicates that the state-of-the-art techniques do not allow UT examination) and that cannot be.radiographed due to (1) geometry and/or interference from surrounding structures or (2) the systems cannot be drained without draining the RPV.
For those welds that are known to present limitations to examination (such as those inside containment penetrations), please provide specific-relief requests.
RESPONSE
The category B-J (Pressure Retaining Welds in Class 1 Piping) and category B-K-1 (Integrally welded Attachments for Class 1 Piping) which present limitations to examination are summarized in to this letter along with appropriate relief requests.
The relief requests are numbered so as to be consistent with other relief requests for the Class 1 Section XI program.
REQUEST 6.
2.4.4 Relief Request on Class 1 System Hydrostatic Testing (p 2-13)
(a)
Please show why the relief valves of lowest setting cannot be gagged shut for performance of hydrostatic tests.
RESPONSE
The Target Rock technical' manual for model 67F safety / relief valves describes.a bench test gagging method for 90% of set point (904.5 psig) utilizing a special gagging tool..The technical manual'also cautions against exceeding-this pressure.
By letter dated December. 18, 1984, Philadelphia Electric Company has requested Target Rock to
Mr. John F. Stolz Janu'ary 31, 1985
'Page 3 evaluate whether the safety-relief. valve can'be properly.and safely gagged for an' inservice hydrostatic. test at 1085 psig.
'We are expecting a written reply.from Target Rock by February. 7,1985, af ter which we will forward the results of the evaluation to the Commission.
If'any further information is required to complete your review, please do not hesitate to contact us.
Very truly yours,
/~

[
Subject v61ds are partially obstructed i
from examination due to position of pipe clamp. "To perform an entire examination on these hanger-lugs.would necessitate removing-the clamp from the pipe.

'This disassembly would involve performing

L an engineering analysis to ensure proper support of pipe, and. in addition, a temporary support may have to be installed.
, I; 2A-job o.f this scope represents an
-unnecessary risk of an industrial accident,. radiation exposure, and extensive expense, soley to perform approximately 20% of the required-i j

In view of the minimal benefits to be
