Dear Ms. Adensam:

EQUIPMENT QUALIFICATION REGARDING ELECTRONIC TRANSMITTERS

HOPE CREEK GENERATING STATION i DOCKET NO. 50-354 1

l Subsequent.to our letter dated February 25, 1986 (C.A.

- McNeill, PSE&G to E. Adensam, NRC), fifty-three (53) Tobar Model 32 Series 2 transmitters included in the harsh Environ-mental Qualification Program were found to be supplied with polyester housing and base assemblies which were not 2

qualified to the requirements imposed by the procurement specific"4 in and committed to in the HCGS FSAR. This

! was verbally reported to NRC by Tobar, Inc. on February 27, 1986 as a possible 10CFR21 reportable incident. This was then followed by a written report to the NRC as a 10CFR21

reportable incident by Tobar, Inc. in letter dated March l 3, 1986 (T.R. Fisher, Tobar, to Director OI&E, NRC).

{ A program was immediately initiated to qualify the polyester housing and base assemblies to the imposed environmental requirements. During this test program, the electrical

, amplifier assembly of the transmitters failed to function during irradiation testing. This was verbally reported

to NRC by Tobar, Inc. on-March 14, 1986.

As a result, the fifty-three Tobar Model 32 Series 2 transmitters which, although could not be qualified for harsh environmental conditions, are qualified for mild environments, will be replaced with Rosemount Model 1153B transmitters which are qualified for harsh environmental conditions. The qualification of these Tobar and Rosemount transmitters is documented in the HCGS Environmental Qualification Summary

Director of Nuclear 2 3-26-86 Reactor Regulation Seven (7) of the Tobar~ transmitters will be replaced with Rosemount 1153B transmitters prior to fuel load. These seven transmitters are components within the Safety Auxiliaries Cooling System (SACS) and the Residual Heat Removal System (RHR). Six transmitters in the SACS are being replaced to support normal operation of this system which will be required at fuel load, and the seventh transmitter, in the RHR system, was originally planned to be replaced at the time the test plan was developed for the polyester housing / base assembly qualification. The balance, or forty-six (46) of the polyester style Tobar transmitters, will be replaced with Rosemount ll53B transmitters prior to initial criticality.

All fifty-three transmitters being replaced are located in areas outside primary containment, but inside the reactor building. The environmental conditions in these areas are not capable of becoming harsh until after initial criticality is achieved. Therefore, these transmitters will only experience mild environments prior to initial criticality.

The attached FSAR changes reflect the replacement of the Tobar transmitters and provide information that the areas in which these transmitters are located will only experience mild environments prior to initial criticality. These changes will be included in Amendment 15 to the HCGS FSAR.

Revisions will be made to the HCGS Environmental Qualification Summary Report (Rev. 4) to include the transmitter replacements.

These revisions will be included in an addendum which will be submitted with our responses to NRC-EQ Branch questions regarding our letter of February 25, 1986.

Sincerely,

Director of Nuclear 3 3-26-86 Reactor Regulation Attachment C D.H. Wagner USNRC Licensing Project Manager R.W. Borchardt USNRC Senior Resident Inspector H. Garg USNRC EQ Branch

HCGS FSAR 09/85 Radiation exposures to components will be minor and will-be due to two sources: radiation shine, and immersion in airborne radioactivity released in a controlled manner from the reactor building.

The TID from both sources will be less than 100 rads for 180 days.

Environmental Qualification of Safety-Related Electrical Equipment," dated December 1979 (for comment), and IEEE-323-1971, "IEEE Standard for Qualifying Class IE Equipment for Nuclear Power Generating Stations." However, the HCGS environmental ,

qualification program has upgraded qualification of equipment to '

l the requirements of NUREG-0588, Category I and IEEE 323-1974.

Components of the NSSS Class IE electrical equipment in a harsh i environment are qualified by test, or a combination of testing and analysis. Those components used in more than one system, which can be or are located in different plant areas, are
