portions of the Reactor Water Cleanup (RWCU) System that were replaced with IGSCC resistant material during the 1990 refueling outage . . . The l resulting new .w elds are identified in the comments column of the new L listing and the - welds removed by the RWCU . pipe replacement have _ been t

L deleted. All inaccessible welds have been classiffwd as IGSCC Category G

l. and Weld RCA-BF-1 has. been reclassified as IGSCC Category D. All welds l reported to have cracks . in Reference 2 have been either replaced or I

repaired, or were. misidentified as having cracks and have been corrected accordingly in the attachment. No welds described 'in the attachment have

. flaw indications, consequently there are no.IGSCC Category F welds.

2. Your responses declined ;to propose a Technical Specification. change' that -

includes a statement on- inservice inspection (ISI) as required by this 1 generic letter. This position 1s .not acceptable. NPPD:should propose.an C

, amendment to the Cooper Technical Specifications as required by Generic Letter 88-01. The model specification for boiling water reactors that was >

. provided in Attachment B to the generic letter should be . utilized unless I changes are necessary to accommodate plant specific differences at Cooper Nuclear Station.

NPPD Response:

l The District committed, in Reference 3, to be in conformance with .the l' stated staff positions . contained in Generic Letter 88 in regards to

, schedule, methods and personnel, and sample expansion. . This commitment is-l identical in content to the model Technical ~ Specification contained in the-Generic Letter. The District ' is adhering to ' this commitment and 'will continue to do so. The District does not believe . amending the Cooper Nuclear Station Facility Operating License to incorporate this. commitment into the Technical Specifications is necessary .and requests that the NRC reconsider its position on this item.

3. NPPD has also declined to propose an amendmeht to 'the Technical "

Specifications that limits the increase in unidentified leakage to 2 gpm over a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or less, as required by Generic Letter 88-01.- -

Your position is unacceptable. NPPD should propose the required Technical Specification.

NPPD Response:

As described below, the District ' believes the existing leakage- detection Technical Specifications are adequate.

a) There are no IGSCC Category D, E, F, or G welds inside the CNS containment with the exception of weld RCA-BF-1. This particular weld i is on the capped CRD return line- to the pressure vessel and has an inner diameter less than four inches. This weld was inspected during the 1990 refueling outage with no crack indications detected. While-the TER notes : that the scope of the subject generic letter is not limited to the welds inside the containment, the leakage detection systems in question are confined to the primary containment.

U.S. Nucir:r RegulItory Comminion 1 April.30, 1990-pig 3' 3 I

b) As a result of . finding IGSCC cracking in 1983, the NRC issued ' a Confirmatory Order to the District, Reference 4,=on September 1, 1983.

The order directed enhanced leakage monitoring due to uncertainties in

. crack sizing and growth.- .The District believes this Confirmatory Order was ' issued solely' on the basis of identified cracks . in large'.

bore IGSCC susceptible piping-inside Cooper's-containment'.

L c) A July 20, .1987- letter, Reference 5, removed the enhanced leakage -

detection requirements -because. the NRC had determined that the.

circumstance (IGSCC cracking) that had led to- the Confirmatory ' Order (enhanced leakage requirements) was no longer applicable, d) The District's basis regarding unidentified leakage' rateL is described in. Cooper's : Updated Safety Analysis Report, Section IV-10. The 5.gpm rate in Section 3.6.C - of the. Technical Specifications is . extremely .

conservative relative to ' 150 ppm determined necessary to1. indicate i rapid crack propagation.

L I

e) The District . replaced IGSCC susceptible piping in '1985 to. ensure tho' continued safe operation of Cooper and ensure Cooper :would meet General-Design Criteria 4',L14, and 31.  ?

In summary, the District , believes ' any :- submission regarding ' enhanced I leakage technical specifications: 10 unwarranted- andf is voluntary in nature. Just six monthc1before.the lasuance of Generic Letter 88-01, the >

NRC Staff agreed with the District' regarding enhanced leakage - detection- .]

requirements at ' Cooper. Since the ' existing . leakage specification adequately provides for - the ; public health and safety, the District' believes the previous . staff position (Reference 5) regarding leakage '

detection is adequate and does not-. plan to submit a Technical

  • L Specification change in this regard.

l

4. NPPD's position on reporting. of flaws and' flaw evaluation -is: not.in conformance 'with the NRC staff position stated in Generic- Letter 68-01. NPPD- should modify its position on reporting requirements and repair criteria to conform to the NRC staff position 'as required in Generic Letter 88-01.

5 NPPD Response:

The District will conform to the NRC Staff . position on reporting.

requirements as' stated in Generic Letter 88-01. Th'e District will notify -

the NRC of any flaws identified that do not meet IWB-3500. criteria of Section XI of the Code for Continued Operation without evaluation, or a change found in condition of welds previously known to be cracked. The' -

District will also notify the NRC of flaw evaluation required for continued operation and/or flaw repair plans.
