SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 167 TOFACILITYOPERATINGLICENS[N_n.NPF-3 TOLEDO EDILJN COMPArlY CENTERIOR SERVICE COMPANY ANE THE CLEVELAND ELECTRIC ILLUMINAT)NG COMP /sY PAVIS-BESSE NUCLEAR POWER STATION, UNIT NO. 1 (MKET NO. 50-346
1.0 INTRODUCTION
By letter dated August 21, 1989, as supplemented September 1, 1989, Toledo Edison Company (the licunsee) proposed changes to the Technical Specifications (TSs) for the Davis-Besse Nuclear Power Station, Unit No. 1.
The proposed changes would remove all line iters using the term " status" in TS Table 3.3-10, " Post-Accident Monitoring Instrumentation," and TS Table 4.3-10,
" Post-Accident Monitoring Instrumentatica Surveillance Requirements."
In addition, the line item on containment vessel hydrogen would be removed from the above two tables, and a monthly channel check for the hydrogen analyzers would be added to TS 3/4.6.4, " Combustible Gas Control." Also, changes to the bases would be made to clarify that the hydrogen analyzers are part of the plant post-accident monitoring instrumentation.
- Finally, several administrative changes are proposed to be made ii clarification purposes.
2.0 EVALUATION TS Tables 3.3-10 and 4.3-10 have 14 of 34 items listed which utilize the term " status." Examples of these line items are " Auxiliary Feedwater Status," "SFAS Status," and "RPS Status." An exact definition for " status" that would cover ail 14 line items ccnnot be determined.
In fact, different definitions for each of the 14 line items cannat be definitely determined either.
A general understanding of the term " state" can be determined from Regulatory Guide 1.97, Pevision 3. " Instrumentation for Light Water-Cooled Nuclear Power Plants to Assess Plant and Environs Conditions During and 9112310220 911217 R
TDOCK 0500 6
2 Following an Accident"; however, as stated above, no exact definition can be determined.
As a result, the TS for these line items have little meaning, because they are subject to a large amount of interpretatinn.
NUREG-0103, Rev. 4 " Standard Technical Specifications for Babcock and Wilcox Pressurized Water Reactors," does not list any line items containing the term " status" in its corresponding TS Table. The licensee has determined that none of their 14 line items containing the term " status" are needed and, therefore, proposes to delete them.
The NRC staff has reviewed this issue and finds that these 14 TS line items are not meaningful and are not needed. Therefore, the NRC staff approves their deletion.
The licensee proposes to delete the line item on containment vessel hydrogen from TS Tables 3.3-10 and 4.3-10 and add a monthly channel ch< ck for the hydrogen analyzers to TS 3/4.6.4 Essentially, these changes just transfer the monthly channel check for the hydrogen analyzers from one TS to another TS.
The licensee proposes this transfer, so as to keep all the TS requirements on the hydrogen analyzers in the same place in the TS. The NRC staff has reviewed this transfer of the monthly channel check and concludes that it is acceptable.
Along with the transfer of hydrogen analyzers monthly channel check, the licensee has proposed TS bases changes that state that the containment hydrogen analyzers are considered part of the plant post-accident monitoring instrumeatation even though their operability requirements are located in TS 3/4.6.4 The NRC staft has reviewed these bases changes and finds them to just be clarifying changes. Therefore, the NRC staff c n cludes that they acceptable.
The administrative changes propc,ed by the licensee consist of renumbering of items,. clarifying title changes, and deletion of an expired footnote.
The NRC staff has reviewed these changes and finds that they are i
administrative in nature. Therefore, the proposed changes are acceptable.
l 3.0 STAT' CONSULTATION in accordance with the Commission's regolations, the Ohio State official was notified of the proposed issuance of the amendment. The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
3.0 ENVIRONMENTAL CONSIDERATION
S i
This amendment involves a change to a requirement with respect to the instal-l lation or use of a facility comporent located within the t estricted area as l
defined in 10 CFR Part 20 or a change to a surveillance requirement. ihe staff has determir.ed that the amendment inycives no significant increase in the w
Y
3 amounts, and no significant change in the types of any effluents that may bereleasedoffsite,andthatthereisnosignificantincreaseinindividual or cumulativt occupational radiation exposure.
The Comission has previously issued a proposed finding that the amendment involves no significant hazards censideration and there has been no public coment on such finding (56 FR 49929).
Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). This amendment also involves changes in recordkeeping, reporting or administrative procedures or requirements.
Accordingly, with respect to these items, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
5.0 CONCt.USION The staff has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safet not be endangered by operation in the proposed manner, (2) y of the public will such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
