-REQUEST FOR LICENSE AMENDMENT DRYWELL HYDROGEN /0XYGEN MONITORS - ADMINISTRATIVE CHANGES

SUMMARY

In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101, Carolina Power & Light Company (CP&L) hereby requests a revision to the Technical Specifications (TS) for the Brunswick Steam Electric Plant, Unit No. 2. The proposed changes, which are administrative in nature, revise TS Tables 3.3.5.2-1 and 4.3.5.2-1 and TS 3/4.6.6.4 to reflect requirements for the drywell/ suppression chamber hydrogen and oxygen analyzers recently issued as Brunswick-2 Amendment No. 99.

DISCUSSION On August 13, 1984, the Commission issued Amendments 73 and 99 to the Operating Licenses for Brunswick-1 and Brunswick-2, respectively. These amendments incorporated Technical Specification changes relating to NUREG-0737 items concerning monitoring of radiation releases, containment conditions, and '

control room habitability. One of these TMI Action Plan items (II.F.1.6) dealt with containment hydrogen monitoring for Brunswick-2.

The Technical Specifications for Brunswirt-1 concerning TMI Action Plan Item II.F.1.6, containment hydrogen monitors were previously issued by Amendment 63 dated December 28, 1983. These Brunswick-1 Technical Specification changes included the incorporation of revised instrument tag numbers in TS Tables 3.3.5.3-1 and 4.3.5.3-1 (accident monitoring instrumentation), the. deletion of references to drywell oxygen concentration monitors in TS Table 3.3.5.2-1 and 4.3.5.2-1 (remote shutdown monitoring instrumentation), and the incorporation of revised instrument tag numbers and calibration gas sample ranges in TS 3/4.6.6.4 (gas analyzer systems).

During the preparation of the March 2, 1984 request (which resulted in Amendment 99 for Brunswick-2), CP&L inadvertently did not identify TS Tables 3.3.5.2-1 and 4.3.5.2-1 (remote shutdown monitoring instrumentation) or TS 3/4.6.6.4 (gas analyzer systems) as needing revisions in order to be 0410gogoNhp..u. sir.., . e. o. eo, ist , . n., ,on. n c. 27802 4 @

Mr. Dl. B. Vcciallo consistent with (1) the proposed TS-to address TMI Action Item II.F.1.6, and (2). the same requirements in the Brunswick-1 Technical Specifications.

Consequently, these Technical Specification- requirements were not revised when the Brunswick-2 Amendment 99 changes were issued.

The enclo' sed Technical Specification changes delete item 7, drywell oxygen concentration, and renumber items 8,-9, and 10 in TS Tables 3.3.5.2-1 and

-4.3.5.2-1. The drywell' oxygen concentration indication on the remote shutdown panel has'been removed as part of the replacement.of the existing drywell I hydrogen / oxygen monitoring system with a new wide-range monitoring system.,

.The changes enclosed are consistent with both the existing Brunswick-1 Technica1' Specifications and the GE/BWR-4 Standard Technical Specifications guidance. The enclosed changes also revise TS 4.6.6.4 by incorporating the increased calibration gas sample ranges necessary due to the increased

' measurement range of the new hydrogen and oxygen monitoring system and by

' incorporating' revised instrument tag numbers. Similar Technical Specification changes were previously issued as Amendment 63 for Brunswick-1.

SIGNIFICANT HAZARDS ANALYSIS

The Commission has provided guidance concerning the application of its standards-set forth in 10 CFR 50.92 for no significant hazards consideration by providing certain examples published in the Federal Register on April 6,

.~ 1983 (48_ FR 14864) . Examples of an amendment likely to involve no significant hazards consideration include: (1) a purely administrative change, and (2) a change that constitutes an additional limitation, restriction, or control not presently included in 'the Technical Specifications. The revised calibration I

' gas sample ranges are needed to reflect the increased measurement range of tha new monitoring system and, therefore, constitute additional limitations. The i deletion of drywell oxygen concentration from the remote shutdown instrument

panel constitutes an administrative change since the change is consistent with the previously approved Brunswick-1 TS and the GE BWR-4 standard TS guidance and reflects the actual plant installation. In addition, TS addressing this equipment are already included as part of the accident monitoring instrumentation listed in TS Tables 3.3.5.3-1 and 4.3.5.3-1. The changing of instrument . numbers in TS Tables 3.3.5.2-1 and 4.3.5.2-1 and in TS 3/4.6.6.4 also represents an administrative change. Since the proposed amendment involves only the addition of new, revised surveillance requirement criteria L and various administrative changes, this request does not result in a significant increase in the probability or consequences of an accident l .previously evaluated, does not create the possibility of a new or different kind of accident from an accident previously evaluated, and does not result in

- a significant reduction in a margin of safety. Therefore, CP&L has determined lthat the proposed amendment f alls under the criteria of Examples (i) and (ii)

and, as'such, involves no significant hazards consideration.

ADMINISTRATIVE INFORMATION The proposed Brunswick-2 Technical Soecification pages are included in

' Enclosure 1, along with a summary of the changes made to each page. Carolina Power & Light Company has evaluated this request in accordance with the

provisions of 10 CFR 170.12 and has determined that an application fee is

required. A check for $150.00 is enclosed in payment of this fee.
