\. ,g/ April 9, 1998 DOCKET: 70-7002 CERTIFICATE HOLDER: United States Enrichment Corporation Portsmouth Gaseous Diffusion Plant Portsmouth, Ohio SUBJ, ..;T: COMPLlANCE EVALUAflON REPORT: APPLICATION DATED FEBRUARY 27,1998, ADDITIONAL CRITICALITY ACCIDENT ALARM SYSTEM (CAAS) FACILITIES BACKGROUND On February 27,1998, United States Enrichment Corporation (USEC) submitted a certificate amendment request for the Portsmouth Gaseous Diffusion Plant (PORTS) to add four facilities to Technical Safety Requirement (TSR) Section 2.8, entitled " Specific TSRs for X 710 Laboratory," and to clarify TSR 2.8.1, which is the section describing the associated operational modes.
DISCUSSION USEC's certificate amendment request involves two changes; addition of the conversion shop and cleaning building (X-700), the maintenance and stores building (X-720), the chemical and engineering building (X-760) and the storage warehouse (XT-847) to the existing TSR Section 2.8 for the technical services and laboratory building (X-710), and deletion of the associated operational mode descriptions in TSR 2.8.1. TSR 2.8.3.1, entitled Criticality Accident (Radiation) Alarm System," is the only specific TSR in Section 2.8 which includes sections on mode applicability, limiting conditions for operation, action statements and surveillance requirements. It is noted that the contents of these sections, which were reviewed and approved by the NRC staff at the time of initial PORTS certification, are not being modified by this amendment.
An Inspector Followup Item (IFI), 70-7002/97 206-108, identified in an NRC nuclear criticality safety inspection report for PORTS dated September 29,1997, noted that no specific CAAS TSR existed for the X-700, X-720, X-760 and XT-847 facilities even though fissile material operations (FMOs) involving greater than 700 grams of U235 at an enrichment equal to or greater than 1.0% U235 could be conducted in those facilities, and CAAS coverage was being provided. As such, USEC has proposed to also apply the NRC-approved CAAS TSR for X-710, to X-700, X-720, X-760 and XT-847. The NRC staff has reviewed the proposed amendment and determined that the X-710 CAAS TSR would appropriately apply to FMOs conducted in X-700, X-720, X-760 and XT-847, and would enhance safety by adding more rigor to CAAS operability in terms of maintenance, calibration, testing, etc., in the four additional facilities.

1 In addition to applying the contents of the X-710 CAAS TSR to X-700, X-720, X-760 and I XT-847, USEC has proposed to delete the three operational modes described in TSR Section 2.8.1, namely (1) " General Analytical - analyses of production, ES&H, waste management, technical support, maintenance / fabrication activities," (2) " Uranium Sampling - subsampling uranium hexafluoride," and (3) "Polybottle Operations - movement of polybottles to and from labs and storage areas." According to USEC, there are no specific operational modes associated with the specific TSRs for X-700, X-710, X-720, X-760 and XT-847. The NRC staff has reviewed this clarification and determined it to be appropriate since the current operational modes in TSR 2.8.1 do not apply to TSR 2.8.3.1 (CAAS TSR) which is required to be applicable at all tirnes when more than 700 grams of U235 at an enrichment equal to or greater than 1.0% U235 is present in the facility.
ENVIRONMENTAL REVIEW
!ssuance of the requested amendment to the Portsmouth Certificate of Compliance (GDP-2),
to add X-700, X-720, X-760 and XT-847 facilities to the existing X-710 CAAS TSR and to delete the operational mode descriptions in TSR 2.8.1, is subject to the categorical exclusion provided in 10 CFR 51.22(c)(19) and will not have a significant impact on the human environment. Therefore, in accordance with 10 CFR 51.22(b), neither an environmental assessment nor an environmental impact statement is required for the proposed action.
CONCLUSION Based on the discussion provided above, the NRC staff has determined that adding the X-700, X-720, X-760 and XT-847 facilities to TSR Section 2.8 entitled "Spccific TSRs for X-710 Laboratory," enhances safety and deleting the operational modes listed in TSR 2.8.1 is appropriate and has no significant safety impact. Therefore, the NRC staff recommends approval of this amendment. Region lli staff have no objection to this proposed action.

The NRC staff has revwwed this clarification and determined it to be appropriate since the current operational mod'egin TSR 2.8.1 do not apply to TSR 2.8.3.1 (CAAS TSR) which is required to be applicable at bl(times when more than 700 grams of U235 at an enrichment equal to or greater than 1.0% Ug5 is present in the facility.
