. . Page 1 of 6 PART 1 EQUIPh!ENT QUALIFICATION REQUIREh1ENTS INVOKED BY JCPSL WITil RESPECT TO 125V DC SYSTEh! FIODIFICATION Final Requirements: A description of the then proposed modification, and the modification related equipment design criteria, were included in the enclosure to a letter to the Director of Nuclear Reactor Regulation from I. R. Finfrock, Jr.

dated April 4, 1978 Re: bbdification to 125V D. C. Power System. Within that document it was stated that "All new 125V DC system equipment will be class IE, meeting the requirements of IEEE Standard 323-1974." In addition to the require-ments of this standard and those additional standards referenced by this standard, other standards and codes were--as a matter of good engineering practice--invoked.

A list of all of the standards and codes which have been invoked for the subject equipment is attached as Appendices I, II, and III (Note: Appendix I covers both the batteries and the battery racks), Further, in that the requirements of many of these standards are somewhat general more specific requirements were specified to the respective equipment vendors in the form of detailed procurement specifications.

Jersey Central Power 6 Light 's Quality Assurance and Engineering Departments were, and continue to be, involved with the vendors in assuring they meet the requirements of those procurement specifications which provides adequate assurance that the intent of all the invoked codes and standards will be met. In this same regard, the NRC Region I Office of Inspection and Enforcement has inspected many of the documents which make up this over-all management control system, and their efforts are documented in pages 8 through 13 of their Inspection Report 50-219/78-35. As noted

Page 2of 6 in this docementation (See Appendix IV), no items of noncompliance were found to exist.

Equipment Qualification Interim Requirements: As was also stated in the cover letter of the referenced April 4, 1978 transmittal to the Director of Nuclear Reactor Regulation, "Becau;a of the short lead time available for this modifi-cation, it may not be possible to obtain all of the class 1E equipment identi-fied in the enclosed modification description. Should that be the case, we will complete the modification by the required date using the most qualified equipment availabic at that time, and install the IEEE 323-1974 qualified equipment when it becomes availabic and plant operating conditions permit."

As the situation continued to evolve, it became apparent that the above referenced equipment qualification final requirements could not be met on all the equipment by the end of the 1978 refueling outage, and in those situations equipment was utilized which was the most qualified available at the time.

As indicated in Part 2 of this report, .lCPf L is proceeding with measures to assure that all equipment will be qualified to IEEE 323-1974. If the currently installed equipment can not be qualified it will be replaced with qualified equipment as it becomes available and plant operating conditions permit.

Page 3 of 6 PART 2 STATUS OF EQUIPMENT QUALIFICATIONS WITH RESPECT TO INVOKED EQUIPMENT QUALIFICATION REQUIREMENTS Qualification Status of Batteries and Battery Racks:

With Respect to Final Requirements:

The currently installed new battery "C" and associated battery racks were designed, constructed and installed so as to meet all the Appendix I referenced codes and standards. At this time, however, a shake test pursuant to the guidance of IEEE 323-1974 and IEEE 344-1975 has not yet been completed. This test is currently scheduled for April 1979.

Assuming this test is successful, after JCPSL's receipt and approval of these test results, the new battery "C" and its associated battery racks (as they currently exist at Oyster Creek) will be fully qualified per the Appendix I referenced final codes and standards.

Interim Requirements:

Based on a review of the documentation which exists to describe the existing battery "A" and its associated battery racks, it has been con-cluded that the new battery "C" and its associated racks are of a quality which is greater than that of the existing battery "A" and its associated racks, when new; therefore, installation of the new battery "C" and its associated racks as it was. performed during the 1978 refueling outage both (a) enabled the 125V DC system modification project objective (i.e. provide increased separation in the 125V DC system) to be achieved by the end of the 1978 refueling outage, yet (b) did not give rise to an unreviewed safety question as defined by 10CFR50.59.

Page 4 of 6 Qualification Status of Battery Static Chargers:

With Respect to Final Requirements:

Except for the following open items, both of the subject static chargers (as they are currently installed at Oyster Creek) meet all of the Appendix II referenced codes and standards:

a.) Although the 460V AC input breakers to, and the 125V DC output breakers from, the chargers are physically identical to the breakers which will eventually be installed as 1E qualified breakers, the currently installed breakers lack QA documentation.

The breakers which we anticipate installing as 1E qualified breakers recently arrived at Oyster Creek and, provided the QA documentation is in order, they should be installed within the month.

b.) A shake test was perfomed pursuant to the guidance of IEEE 323-1974 and 344-1975, and on Friday, January 19, 1978, the test report was received by JCPSL. This document is currently being reviewed by JCP6L, the review should be completed within the month.

In summarizing the static chargers equipment qualification status, following installation of the above noted IE qualified breakers, and JCPSL review and approval of the shake test report, both static chargers will meet all the requirements of the Appendix II referenced codes and standards.

With Respect to Interim Requirements:

Based on a review of the documentation which exists to describe the existing battery "A" chargers and physical examinations thereof, it was concluded that the new static chargers are of a quality which is greater than that of the existing chargers (i.e. MG set charger and static charger ); therefore, installation of the new static chargers as it was performed during the 1978

Page 5 Of 6 refueling outage both (a) enabled the 125V DC system modification project objective (i.e. provide increased separation in the 125V DC system) to be achieved by the end of the 1978 refueling outage and yet (b) did not give rise to an unreviewed safety question as defined by 10CFR50.59.

Qualification Status of Motor Control Center:

With Respect to Final Requirements:

The only motor control center added with the subject modification is desig-nated DC-2 on the drawings which were forwarded in our April 4, 1978 submittal, and except for one open item, the motor control center as it is currently installed meets all of the Appendix III referenced codes and standards. The one open item relates to a timing relay which failed in a test of a"fype" unit. The cause of failure at this time appears to be related to the relay's having been thermally aged at an excessive rate.

The test procedures for the subject type test are still being reviewed and it is currently anticipated that thermal aging at a slower rate (while still achieving the same cumulative amount of thermal aging) will result in the relay!s qualifying per the requirements of IEEE 323-1974.

Currently, we are attempting to complete these additional tests by the end of March,1979, and should these tests be accomplished satisfactorily, the motor control center will oc qualified per the requirements of all the Appendix III referenced codes and standards.

With Respect to Interim Requirements:

Based on a review of the documentation which exists to describe the existing motor control center DC-1 and physical examinations thereof, it was concluded that the new motor control center is of a quality which is greater than that of motor control center DC-1; therefore, installation of motor control center DC-2 as it was performed during the 1978 refueling outage both (a) enabled

Page 6 of 6 the 125V DC system modification project objective to be achieved (i.e.

provide increased separation in the 125V DC system) by the end of the 1978 refueling outage, yet (b) did not give rise to an unreviewed safety ques-tion as defined by 10CFR50.59.
