Gentlemen:

Subject: Combined Inspection Report Nos. 50-387/86-25 and 50-388/86-28

Enclosed is the report of the team inspection conducted by Mr. C. J. Anderson

and other NRC inspectors and representatives on November 17-21, 1986, at the

Pennsylvania Power & Light Company office, Allentown, Pennsylvania, and the

Susquehenna Steam Electric Station Units 1 and 2, Berwick, Pennsylvania, of

activitias authorized by NRC License Nos. NPF-14, NPF-22. The team's findings

,{ . were disi;dssed with you and members of your staff at the conclusion of the

6~ 1 inspection) The inspection reviewed your implementation of a program for

establishi.ng and maintaining the quatification of electric equipment within the

scope :of '10 CR 50.49. Within these areas, the inspection consisted of

.

t exanination of' elected procedures and records, interviews with personnel, and

I

observations by the inspyar. ors.

The inspection determined that you have implemented a program to meet the

requirements of 10 CFR 50.49 except fo'r certain deficiencies identified in the

enclosed inspection report. Six deficiencies in your program implementation

summarized in Appendix A, are clas,sified as Potential Enforcement Items. With

regard to these six deficiencies c se are considering appropriate enforcement

action and will inform you of our decision in the future. These deficiencies

involve 1) failure to demonstratA cualification of Valcor high temperature

wire, Rockbestos coaxial cables, Raychem Cable splices; 2) failure to provide

similarity analysis for Target Rock solenoid valves, 3) failure to follow

Procedure DC 151.0 to provide a required document in the EQ binder for four

. . replaced Rosemount transmitters, and 4) failure to ensure qualification of

APPENDIX A

Susquehanna Steam Electric Station 50-387/86-25

Units 1 and 2 50-388/86-28

Potential Enforcement Items

As a result of the equipment qualification (EQ) inspection on November 17-21,

1986, the following items- have been identified as Potential Enforcement Items

(paragraph references are to detailed portions of the inspection report).

1. Contrary to paragraph (f) of 10 CFR 50.49, Pennsylvania Power and Light

Company (PP&L) did not adequately demonstrate qualification of Valcor high

temperature wires, because qualification of these wires was based on ques-

tionable test data (unrealistically high insulation resistance measurements

du-ing simulated LOCA test). Subsequently, interim qualification of these

wires was established before the end of the inspection using additional

data. (Paragraph 4.2.1, item 50-387/86-25-03; 50-388/86-28-03).

2. Contrary to paragraph (f) of 10 CFR 50.49, PP&L did not adequately

demonstrate qualification of Rockbestos coaxial cables currently being

used in the Containment High Range Radiation monitors. The insulation

resistance of these cables was not shown to meet performance requirements

during a LOCA when the temperature exceeds 225*F. PP&L was in the process

of issuing operability precautions to the station at the end of the

inspection. (Paragraph 4.2.2, item 50-387/86-25-04; 50-388/86-28-04).

3. Contrary to paragraph (f.2) of 10 CFR 50.49, PP&L did not adequately

demonstrate qualification of Target Rock Solenoid valves, because no

supporting similarity analysis was provided in the EQ binder at the time

of the inspection. However, PP&L did provide an adequate similarity

analysis before completion of this inspection (paragraph 4.2.3, item

50-387/86-25-05; 50-388/86-28-05).

l 4. Contrary to 10 CFR 50 Appendix B, Criterion V and Procedure DC 151.0, PP&L

l failed to follow their procedure to provide a Replacement Item Equivalency

l Evalutaion (RIEE) in the EQ binder for four replaced Rosemount Transmitters

!

(paragraph 4.3, Item 50-387/86-25-07; 50-388/86-28-07).

5. Contrary to paragraph (f) of 10 CFR 50.49, PP&L did not adequately demon-

l strate qualification of a number of installed Raychem cable splices identi-

l fied by PP&L and documented in their Nonconformance Reports. These cable

l splices were not installed in accordance with the qualification tests and

! the Raychem installation procedures. Justifications for continued operation

! were provided for these splices (paragraph 4.4, Item 50-387/86-25-08;

50-388/86-28-08).

! 6. Contrary to paragraph (f) of 10 CFR 50.49, PP&L failed tc ensure that from

j the required qualification deadline to the time when the Limitorque valve

l

'

operator wiring was replaced as a result of NRC Information Notice 86-03

that certain Limitorque valve operator wiring was qualified. Numerous

l

Limitorque valve operators requiring EQ contained wiring whose qualification

i

could not be demonstrated (paragraph 4.5, Item 50-387/86-25-09;

I

'

50-388/86-28-09).
