UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION AMENDMENT NO.
9 TO NPF-22 SUSQUEHANNA STEAM ELECTRIC STATION UNIT-2 DOCKET NO. 50-388 INTRODUCTION By letter dated January 30, 1985, Pennsylvania Power
& Light Company (the licensee) requested changes to the License Condition 2.C.(7) of Facility Operating License NPF-22.
EVALUATION License Condition 2.C.(7) has been revised to incorporate a November 30, 1985 deadline for the environmental qualification of certain electrical equipment important to safety.
Pennsylvania Power
& Light Company has indicated that for Susquehanna, Unit 2., technical problems with respect to testing and installation scheduling have delayed completion of the qualification program of certain equipment per requirements of 10 CFR 50.49.
PP&L has further indicated that the equipment for which qualification will not be completed by March 31, 1985 can be divided into two categories:
I) equipment for which testing will not be completed, and
- 2) equipment for which modification is required in order to satisfy qualification requirements.
I.
Equipment for which testing has not been completed:
A.
Conduit Seals During the qualification process PP&L recognized the need for conduit seals for certain devices, particularly inside containment.
Since there is no existing sealing material or methodology that had been qualified which would develop the Susquehanna SES in-containment requirements, testing of any new seals is required.
Testing is now underway and is expected to be completed after March 31, 1985.
B.
Silicon Rubber Insulated Cable Silicon rubber insulated cable is used inside the containment for limit switch and solenoid valve circuits.
This cable (rated at 200'C) was selected based upon vendor qualification test reports.
There is a test in progress to qualify this cable for Susquehanna environmental parameters.
C.
NSIS Cabl e Anaconda NSIS FR-EP cable is used inside the containment for connecting 8504080525 850328 PDR ADOCK 05000388 P
~
'h electrical devices.
This cable has been tested by Anaconda to environ-mental conditions which envelop the SSES conditions for all parameters
- except, beta radiation.
The cable is being tested in conjunction with the test for conduit seals.
II.
E ui ment for which modifications are re uired There are a number of equipment items that are having modifications implemented in order to achieve qualification.
These modifications (except item C) are currently scheduled for completion during the refueling outage which began in February 1985 and will end in May 1985.
The following is a brief description of the modifications.
A.
Relocate SGTS Radiation Monitors B.
Replace PDSL Switcher in Common Plenum C.
Replace Terminal Block and Locking Nut on Target Rock Solenoid Valve SV-22651 The staff reviewed the licensee's submittal of January 30,
- 1985, and has concluded that the request for extension is timely and within the scope of 10 CFR 50.49(g) and that PPSL has shown good cause for the extension.
The staff has reviewed the Justifications for Continued Operation and finds them acceptable.
Compliance for Category II components except item II.C is required prior to restart from the current refueling outage.
Compliance for Category I components and item II.C should be achieved at the earliest practicable time, but in no event later than November 30, 1985.
We find that Susquehanna, Unit 2's continued operation during the extension period will not adversely affect the public health and safety.
ENVIRONMENTAL CONSIDERATION This amendment involves a change to a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no signifi-cant change in the types or significant increase in the amounts of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding.
Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR Section 51.22(c)(9).
Pursuant to 10 CFR 51.22(b),
no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
CONCLUSION We have concluded, based on the considerations discussed above, that:
(I) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
Date.
