Frederick W. Schneider Vice President Public Service Electric and Gas Company SO Park Place Newark, N.J. 07101 201/430-7373 Production Mr *. Boyce H *. Grier, 'Director U.S *. Nucl.ear Regulatory Commission Off ice of Inspection & Enforcement Region l 631. Park Avenue.

King of Prussia, Pennsylvania 19406

Dear Mr. Grier :

NRC IE BULLETIN 79-17, REVISION 1 NO. l UNIT SALEM GENERATING-STATION.

December 27, 1979 In response to NRC IE Bulletin-79-17, Revision l, dated: October 29, 1979,.the. following information is-submitted for your review as-a supplemental response to NRC IE Bulletin 79-17:-

A review of safety-related stainless steel piping systems to identify systems and portions-of systems. which contain stagnant oxygenated*

borated water* has been completed.

This review was based on the definition of stagnant oxygenated borated _water systems as g.iven in Section 1 o:E IE Bulletin 79-17, Revision l.

The results of this review have slightly increased the inspection and surveillance-requirements of NRC IE Circular 76-06,..

The:* current re-view addressed the followil'lg s.ystems::

lJ Residual Heat Removal 2J Safety Injection.

3)

Containment Spray

4)

Chemical and Volume Control

5)

Spent Fuel. Cooling All safety-related portions of. the Spent Fuel Cooling System are now continuously circulated and therefore we eliminated it.from the scope of Circular 76-06 and Bulletin 79-1.7, Revision 1. _

In accordance with the requirements defined in Circular 76-06, a pro-

- gram was established to definethe surveillance required at Salem to assure the integrity. of piping exposed to stagnant borated water *.

A copy of this program and the first sixty-day report required by Circular 76-06 were submitted to the NRC by the General Manager -

Electric Production letter of January 26, _1978.

The program and inspection requirements current r.eview of pertinent.systems. -

--r will be updated, based on the 502.

12... 27-79 In response to Section l(a):

~.r.

ll

  • Hydrotesting - Hydrotesting is not scheduled to be conducted until the Third. Inservice Inspection period (1985-1987).. -

\\.

2)
  • Service* Pressure Visual Leak Examinations have be~n conducted as. f o-Ilows:

a):

Safety Injection System (Nuqlear Class 3) -

June 1978 o b)

Charging and Volume* Con'trol, Part 1 (Nuclear Class* 2)

~*

-January 1979*.

c)

Residual. Heat Removal (Nuclear Class 2.) -

September 197 9.

d}

-Chemical and Volume* Control, Parts; 2 and 3 (Nuclear.

Class 2*)... -

November 197"9'.

3 )-

. Service Pressure Visual-Leak Examinations scheduled are* as follows:

af Safety Injection (Nuclear Class 3) -

June 1980*.*,

b)

_Containment Spray (Nuclear Class 2 and** 3.) - June '198"0.

4)

. Volgmetric (UT). Examinations: of welds have been conducted as.

follows:

  • 0

. Fifty-six circumferential J?ipe welds were* examined in the*

Residual Heat Removal, Safety Injection and Chemical: and Volume Control Systems during an outage in 1977.

Fifteen circumfer-

  • ential pipe welds; were examined in. these systems during the* 1979 Refueling.. outage..

The Ultrasonic* Examinations were conducted* by Southwest

.Research Institute during both outages*.

The procedures and qualifications were* in compliance with the* requirements of Section XI,.ASME Coder.1974 Edition, Summer 1975 Addenda..

The* procedures and' qualifications are_' filed in. the PSI and IS'I Plans.

The* !SI.Examination (sampling) Plan is in accord-ance* with.the* same* 1974 Code as is the acceptance criteria.

Data sheets of all seventy~one welds.examined. to date revealed no recordable or reportable. indica*tions, and none of the welds required-corrective actions;

  • In response to* Section 1 (b).:

Periodiq samples are obtained from the stagnant. lines of systems iden-tified by the-requirements. of this*Bulle:tin.

The samples are.analyzed for chloride content 'only.

Our response to IE Cir.cular 76-06 included

  • Mr. Boyce-H.* Grier 12-27-79 the sampling_ and analysis for dissolved oxygen also.

However, those portions of systems affected by Circular 76-06 and Bulletin 79-17

/

are all supplied by oxygen saturated water with high boron concentra-tions.

Accurate oxygen analysis under.these.conditions. is.very diffi-cult and the analysis has very little value.

Therefore, we have elected to. maintain control over the stress-corro'sion cracking pro-pensity in stagnant lines through a program of *chloride analysis of contained fluids,. periodic flushing., and ongoing inspection.. Sample schedules, chemistry specifications, and* corrective action to.be taken have been included in the station Chemistry Procedureso Analysis~ data sheets are included as Attachment l *.

In response ~o S~cti~n l(c~:

Preservice Inspection (PSI) NDE for Salem Unit No. i was conducted between August 1975 and-August 1 1916.

The ex~inations were conducted.

and results were accepted. in accordance with the criteria:established.

. in.section. XI,* ASME Code, 1971 Edition, Winter 1972* Addenda..

Hydro-testing. of systems and visual leak examinations. were conducted in. ac-cordance :with USAS. B31. 7 (Nuclear Power Piping) *.

. ing safety-related systems that contain. fluids of: interest were in-cluded' in the PSI Examinations.when and to the extent they.were :i;-e-quired,.by the Code:

lL

.. 2).

. *. 3) 41 Residual Heat Removal Safety Injection Co-ntainment. Spray Chemical *and: Volume Control-In: response to* Section l(d)::

System. inspections' and weld examinations: to date reveal no instance

  • of cracking in identified. systems.

In response to Section 2:

Since !SI Examina,tions: have been performed on stagnant portions. of -

systemsr pr.eviously identified,, in*spection* has been. done* in accordance with the. original: Bulletin and the requirements' of Section.2* of this Revision are also* satisfied *.

If' you* require addition.al inforination*,. we: wil-1 be* pleased to discuss,

it with* you *.

Sincerely,
