SUBJECT:

Waterford 3 SES Docket Number 50-382 Environmental Qualification Rosemont Transmitters Model 1153A

Reference:

W3P83-0320 dated January 27, 1983

Dear Mr. Knighton:

As indicated in Enclosure 3, page 71 of the reference submittal, additional information is required to resolve the aging and operability issues of the subject transmitters. The purpose of this letter is to supply the neces-sary information.

A resolution and supporting reports, which are included as attachments, provide an explanation on how the conclusion was reached that these transmitters are qualified for 6.5 years in containment or 19.3 years out-side containment. These attachments are also intended to represent our justification for interim operation for the Rosemont ll53A transmitters.

If you have any questions on this submittal, please advise.

Sincerely,

(. Q m ,

Resolution Attachment 1 The qualification lifetime for safety related transmitters used at the Waterford-3 Steam Electric Station has been questioned by the NRC.

The present objective is to establish a qualified life for the Rosemont 1153 Series A transmitters presently installed at various locations in the containment and reactor auxiliary buildings at Waterford-3.

The Rosemont Model 1153 A transmitters used in containment and in the reactor auxiliary building were purchased to IEEE 323-1971 qualifications through the NSSS and Ebasco contacts for Waterford-3.

Subsequent to this purchase, the IEEE 323-1974 was issued which required thermal aging as part of the qualification testing. The Rosemont 1153 A transmitters are not qualified to the 1974 methodology.

Although the purchase orders predate the IEEE Standard, Louisiana Power

& Light Company has elected to comply, where feasible, with the more conservative requirements. Therefore, we contracted EDS Nuclear to provide an analysis for the qualified life of the Rosemont 1153 A transmitters.

The basis of the EDS analysis is a qualification test performed by Westinghouse and calculations which use Arrhenius techniques. The question of qualification has arisen since the issuance of the Westing-house Report in which three out of four 1153 A transmitters failed in post-LOCA environment.

The thermal portion of the Westinghouse test is considered valid because the three failed samples did not fail as a result of common mode. The first of the three failed test units presented erratic readings and was considered a random failure which was not attributed to testing. The second failure was caused by a degraded cable entry seal which allowed caustic boric acid spray to enter the dye cavity and caused output errors. The third failure was due to a cable entry seal fitting which leaked and allowed the boric acid spray to enter the terminal side of the electronic housing. The fourth test specimen passed the LOCA test.

Since two of the three failures were attributed to degraded cable entry seal, which were not within the scope of the test, and since Ebasco is providing cable seals which are environmentally qualified I for incontainment services and the third failure is considered random, EDS concludes that the 1153 A transmitters are qualified based on the successful testing of the fourth sample.

Using the Arrhenius methodology, the calculated lives of the ethylene-propylene o-rings used in the 1153 A transmitters are 149 and 644 years for inside and outside containment, respectively. The limiting sub-component of the transmitter was found to be the epoxy glasa laminate circuit board. The conclusions of the EDS analysis are that incontain-ment transm i tters have a qualified life of 6.5 years, and those in the

RAB have a qualified life of 19.3 years. The.EDS analysis also recommends that these transmitters be replaced prior to the end of their qualified life and that they be periodically maintained using the manufacturer's procedure.

The recommended maintenance and surveillance program includes the following:

1) Calibration and maintanance procedures provided in the Rosemont Instruction Manual #4295.
2) The cover gaskets should be replaced each time the transmitter's cover is removed.
3) Should random transmitter failures occur, it is desirable to replace these transmitters with ones which have greater qualified life.
4) These transmitters will be replaced individually prior to the end of their qualified life.

LP&L concurs with the EDS conclusions and recommendations.
