t plate. : The liner plate' has 'a 2-1/2'!. diameter hole = drilled through

~

-it to allow installation of ascathodic' protection-electrode., Since

the ' electrode is. inoperable; sampling ofL.the l groundwater beneath zthe :

liner ; plate 'was required f to: ~ determine the ' corrosiveness - of thel groundwater on the. liner plate.. To ' obtain ' the water l sample, a 1/2'?

plug was removed from 'a 1/2"i half coupling! on. the.~ 4" pener ration -

- pipe. Once the sample was obtained, the plug _was to be-reinstalled,.

r seal-welded, and: a ' leak rate, test 1 performed; Howeverf groundwater;

' leakage' by the' plug' and coupling threads; has prevented: obtaining anj acceptable weld., To qualify. the penetration, a' 1-1/2',' diameter pipe will' be placed over the ' existing coupling and plug and! welded (on the

'4" pipe. 'A 1-1/2" pipe cap will then.be installed on:the'end of the 1-1/2"fpipe and seal-welded.

Component for Which Relief is Requested:

A.

Name and Number Nuclear Service Water System (RN), Weld Number RNIF-427 adjacent to Valve 1RN134A.

B.

Function

.Provides cooling water to Containment Spray Heat Exchanger "1A".

C.

ASME Section III Code Class l

Equivalent Class 3,

Design pressure 135 pai, Design temperature

)

95*F.

i D.

Materials and Welds Carbon steel

pipe, SA-106 Grade B, 0.375 wall thickness, 18" diameter l

2.

ASME Code Section XI Requirement Determined to be Impractical -

ASME B and PV Code,Section XI, 1980 Edition through winter of 1980 Addenda, Article IWA-4000, and Section III, 1971 Edition, Article ND-5000.

3.

Basis for Requesting Relief:

Dye penetrant inspection was not performed on weld repair to root side (inside pipe) of weld RN1F-427, 4.

Alternate Examination:

A.

Perform limited ultrasonic inspection (UT) at both 45 and 60 degree angles on the entire area of RN1F-427.

This limited inspection is based on valve to weld configuration.

B.

This weld and adjacent welds RN1F 58-1 and 58-2 will receive an inservice leak inspection.

5.

Implementation:

Refueling Outage E00-4, 1987
