1.0 INTRODUCTION
By letter dated April 13,
- 1987, Pennsylvania Power and Light Company (the licensee) submitted Change Request No.
93 to NPF-14 and Change Request No.
46 to NPF-22 requesting that the Technical Specifications (TS) Table 4.3.2. 1-1, Isolation Actuation Instrumentation Surveillance Requirements, be amended to revise the applicable operational modes requiring surveillance of the Standby Gas Treatment System (SGTS) Exhaust Radiation-High instrumentation.
These changes are proposed to be consistent with the SGTS Exhaust Radiation-High instrumentation operability requirement specified in TS Table 3.3.2-1, Isolation Actuation Instrumentation.
The proposed changes consist of modifying the surveillance requirement on the SGTS Exhaust Radiation-High, instrumentation Item 1.d (both units) of TS Table 4.3.2. 1-1 such that the surveillance is performed in modes 4 and 5 only when venting or purging is planned.
The current TS requires the surveillance to be performed and maintained while in modes 4 and 5.
- 2. 0 EVALUATION The SGTS Exhaust Radiation-High instrument is designed to provide automatic closure of the primary containment purge and nitrogen makeup isolation valves when high radiation is detected in the SGTS exhaust vent during containment purge.
This is done to prevent the release of radioactivity to the environment should a reactor coolant leak occur.
The existing TS requires performing and maintaining surveillance of the SGTS Exhaust Radiation-High monitoring instrument during modes 4 and 5.
However, in Table 3.3.2-1, under the "Applicable Operational Condition" column, the SGTS Exhaust Radiation-High instrument is required to be operable in modes 4 and 5 only when venting or purging the drywell per TS 3. 11.2.8.
The licensee has requested that the TS Table 4.3.2. 1-1 for both units be amended to make it consistent with TS Table 3.3.2-1 (operability) and require surveillance consistent with TS 3. 11.2.8, when venting or purging the drywell.

The staff finds that this change does not conflict with current guidance provided in NUREG-0123, Standard Technical Specifications (STS) for General Electric Boiling h'ater Reactors or the staff Technical Position CSB 6-4.
The licensee's approach is, therefore, acceptable.
The staff therefore concludes that the licensee's proposal to modify TS Table
-4.3.2. 1-1, Item 1.d to require surveillance in modes 4 and 5 only when venting or purging the drywell is acceptable.
- 3. 0 ENVIRONMENTAL CONSIDERATION This amendment involves a change to a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes to the surveillance requirements.
The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no siqnificant 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 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of this amendment.
- 4. 0 CONCLUSION The Commission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Re ister (52 FR 26594) on July 15, 1987 and consulted with the State o~ennsy van>a.
No public comments were received, and the State of Pennsylvania did not have any comments.
The staff has concluded, based on the considerations discussed above, that:
(I) there is reasonable assurance that the health and safety of the public wi 11 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 nor to the health and safety of the public.
