Date of amendment request: February 25,1997 Brief description of amendment: On February 25,1997, USEC submitted a request to provide for an additional identified criticality accident case for the X-333 cascade building related to the previously approved increase in assay limit to 3 percent. The operation at increased assay creates conditions where the location of an inadvertent nuclear criticality event might be closer to the X 333 Area Control Room (ACR 1), thus producing higher potential doses to personnel at that location, it should be noted that this hypothetical accident case was identified by USEC af ter the NRC approved USEC's initial certificate application in November 1996. It should also be noted that the increase in the X 333 assay limit was approved by the NRC as part of initial certification of PORTS. For this hypothetical accident case, an estimate is made that personnel in ACR 1 could, under the conservative assumption that they remained in ACR 1 for 50 minutes despite the likely criticality alarm, receive a dose of 49 rem and not 0.005 rem as ir ;urrently indicated in the Accident Analysis section of the PORTS Safety Analysis Report (St ~.).- Based on an initial review of the amendment request, the NRC staff feels that sufficiently adequate safety l controls are currently in place at PORTS to prevent and mitigate this accident. Therefore, i other than the proposed modification to the PORTS SAR, this amendment would likely not j

-l require any other changes to plant operations. 1
