' NUCLEAR CRITICALITY SAFETY DOUBLE' CONTINGENCY PRINCIPLE BACKGROUND-On June 16,1997, United States Enrichment Corporation (USEC) submitted,in accordance with a commitment made in its certificate application, a request to add an additional criticality safety program element to the list of elements committed to in Portsmouth Gaseous Diffusion Plant (PORTS) Technical Safety Requirement (TSR) 3.11.1.
Section 3.9 of the PORTS Safety Analysis Report (SAR) Revision 4 dated July 26,1996, summarizes the upgrades required to bring the process f acilities in compliance with the descriptions provided in SAR Chapter 3. One of the upgrades involves the !dentification of Structures, Systems and Components (SSCs) also referred to as / Q NCS SSCs, and
- associated support systems required to meet the nuclear criticality aafety (NCS) double contingency principle. Issue 23 of the Compliance Plan (DOE /ORO-2027/R3) required USEC to ider.tify AQ-NCS SSCs and their associated support systems and delineate the boundaries of AQ-NCS SSCs, before March 3,1997. According to USEC, this action has been completed. A commitment made in SAR Section 3.9.10, entitled " Identification of Nuclear Criticality Safety SSCs," requires USEC to follow-up by revising TSR 3.11.1 to reflect ide.ntification of AQ NCS SSCs and their associated support systems. As such, USEC has proposed a new fourth bullet to TSR 3.11.1 to state:
Identification of SSCs and support systems necessary to meet the double contingency principle.
- described in the SAR. It also requires the NCS program to address adherence with ANSl/ANS standards, NCS responsibilities, NCS process evaluation and approval, design philosophy and review, criticality accident alarm system coverage, procedure requirements, posting and labeling requirements, change control, surveillance and assessments, and technical aspects.1r. addition to these existing elemental requirements, this amendment dscumcnts the requirement of identification of AQ-NCS SSCs end support systems. The Quality Assurance (OA) requirements applied to SSCs are designated r,s AQ-NCS, in accordance with USEC's QA Plan submitted as part of the PORTS certification application.

--2; ENVIRONMENTAL REVIEW--
' Issuance of an amendment to the Portsmouth Certificate of Compliance (GDP-2), by adding an additional TSR commitment related to the PORTS NCS program by requiring
' ide.ntification of SSCs and support systems necessary to meet t' e double contingency principle, is subject to the categorical exclusion provided in-10 CFR 51.22(c)(19).
Therefore, in accordance with 10 CFR 51.22(b), neither an environmental assessment nor an environmental impact statement is required for the proposed action.
CDNCLUSION Tne NRC staff has determined that the additional requirement of identifying and maintaining SSCs and support systems relied upon by USEC to meet the NCS double contingency principle, will not significantly increase the potential for, or radio'ogical or chemical
- consequences frum, previously analyzed accidents, and will not result in the possibility of a
- new or dif.4 rent kind of accident. In addit!on,' the NRC staff has determined that this
- amendment will not result in a significant reductio.)in any mcgin of safety, nor will it result in an overall decrease in the effectiveness of the plant's safety, safeguards, or security programs. On the contrary, this amendment may constitute an increate in the NCS margin of safety and in the effectiveness of the plant's NCS program. Therefore, the NRC staff recommends ap,nroval of this amendment.
