1.0 INTRODUCTION
By application dated April 18, 2001, South Carolina Electric & Gas Company (SCE&G, the licensee) requested changes to the Technical Specifications (TS) for the Virgil C. Summer Nuclear Station (VCSNS). The proposed changes would revise volumetric air flow units for TS 4.7.6.c.1, c.3, e.1, e.3, f, and g to identify standard air flow units expressed as standard cubic feet per minute (SCFM). Volumetric air flow units for TS 4.6.3.b.1, b.2, c.1, and d, and TS 4.9.11.b.1, b.3, d.1, e, and f are being revised to identify actual air flow units and are expressed as actual cubic feet per minute (ACFM).
2.0 EVALUATION ACFM and SCFM are units for volumetric air flow rates. ACFM is a measure of the actual volumetric air flow rate at the conditions of the air stream. The density of air varies with temperature and pressure. SCFM is a measure of the volumetric flow rate if the air stream were at standard conditions. Standard conditions are defined as 70BF and 1 atmosphere pressure.
The term CFM currently used at VCSNS is an acronym for cubic feet per minute and does not properly relate to design considerations nor does it account for the effect of air density. Design air flow is typically based on air at standard conditions. Volumetric air flows measured for the surveillances of TS 4.7.6 are converted for air density changes and expressed in SCFM. The existing nomenclature of CFM does not present this information adequately. Volumetric air flows measured for TS 4.6.3 and TS 4.9.11 are expressed in ACFM due to their specific design application.
The NRC staff finds this change acceptable because these terms clarify the units of air flow relating to the conditions required by the affected TS. The change does not increase the probability of an accident, there is no adverse effect to equipment safety, nor is there a reduction in margin of safety.
3.0 STATE CONSULTATION
In accordance with the Commissions regulations, the State of South Carolina official was notified of the proposed issuance of the amendment. The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendment changes surveillance requirements. The NRC 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 significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (66 FR 29361). Accordingly, the 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 or environmental assessment need be prepared in connection with the issuance of the amendment.
5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
