DOCKET NOS. 50-334 AND 50-412 INTRODUCTION Surveillance requirement 4.4.9.1.c of the Beaver Valley Technical Specifications requires the removal and examination of the reactor vessel surveillance capsules to update the plant heatup and cooldown curves. Table 4.4-5 " Reactor Vessel Material Irradiation Surveillance Schedule" imposes the capsule removal schedule including vessel location, lead factors and estimated capsule fluence.
t By letter dated April 21, 1989 Duquesne Light Company (the licensee, acting as agent for the above utilities) requested that both specification 4.4.9.1.c and Table 4.4-5 be deleted. Our review of that request follows.
DISCUSSION AND EVALUATION 10 CFR 50, Appendix H, " Reactor Vessel Material Surveillance Program Require-ments" imposes requirements on light water reactor licensees to monitor changes in the fracture toughness properties of reactor vessels. The changes are caused by neutron irradiation and the thermal environment. Under the program, fracture toughness test data are obtained from material specimens exposed in surveillance capsules, which are withdrawn periodically from the reactor vessel.
A proposed withdrawal schedule, which is the subject of Table 4.4-5 and specification 4.4.9.1.c of the Technical Specifications (TS), must be submitted for staff approval. Therefore, Table 4.4-5 of the units' TS contains the staff-approved specimen withdrawal schedule.
The licensee proposed to relocate Table 4.4-5 from the TS to the Updated Final Safety Analysis Report (UFSAR) of each unit. The licensee provided draft UFSAR pages to show this. Such relocation does not change the subject surveillance requirement or the design of specimen capsules in any way.

amendment, we approve re, location, but not substantive change, of a sur By this requirement. The specimen withdrawal schedule in Table 4.4 5 will continue inclusion in the UFSAR; any future changes to the specimen schedule will require prior staff approval, as specified in Section II.B Appendix H of 10 CFR 50. Hence, the reactor vessel su an be We therefore find the deletion of Table 4.4-5 and specification 4.4.9.1.c acceptable.
The associated bases of specification 4.4.9.1.c is also revised to reflect the relocation of Table 4.4-5 to UFSAR Table 4.3-6.
This change is also acceptab.le.
ENVIRONMENTAL CONSIDERATION facility components located within the restricted area as Part 20.
We have determined that the amendments involve no significant effluents that may be releat;e offsite, and that there is no increase in individual or cumulative occupational radiation exposure.
previously issued a proposed finding that these uendments invohe ne significan t<e have hazards consideration and there has been no public coment on suci. finding Accordingly, these amendments meet the eligibility criteria for categorical exclusionsetforthin10CFR51.22(c)(9). Pursuantto10CFR51.22(b) environmental impact statement or environmental assessment need be prepared connection with the issuance of these amendments.
CONCi.USION We have concluded, based on the considerations discussed above, that:
there is reasonable assurance that the health and safety of the public(1) 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 (3) the issuance of the amendments will not be fnimical to the common defense and security or to the health and safety of the public.
