SUBJECT:
JANUARY 13,1999, CONFERENCE CALL
SUMMARY
PORTSMOUTH GASEOUS DIFFUSION PLANT (PORTS) SEAL EXHAUST (SE) PUMPS On January 13,1999, Melanie Galloway, Jack Davis, Dave Hartland, Courtney Blanchard and myself had a conference call with Mark Smith, Ed Wagner, Al Stone, Mike Hone and Ralph Leming of the United States Enrichment Corporation (USEC) to discuss a nuclear criticality safety (NCS) concern the staff had related to the current operations of the SE pumps at i PORTS. Specifically, the staff was in possession of what it considered conflicting information regarding the internal volumes of the SE pumps which could become available for a UF6/ oil mixture following a compressor seat failure. For example, PORTS Safety Analysis Report Table 3.1.1.6-1 entitled " Seal Exhaust Pump Sizes," under the column entitled " Maximum Amount of Oil," indicates this maximum volume for the Area 3 Kinney 100-cfm to be 3 gallons.
In a phone conversation I had with USEC on January 7,1999, I was told that the maximum oil I volumes reflected in PORTS SAR Table 3.1.1.6-1 would be the maximum amounts that the l UF6/ oil mixtures could attain in the SE pumps with the oil overflows in place. However, USEC's l response dated February 20,1998, to our RAI on a related certificate amendment request, !
indicates the maximum volumes for Area 3 pumps range between 6.7 to 7.45 gallons. In l
addition, an internal PORTS memorandum dated November 9,1995, from Jeremy Smith to David W. Thompson and Dave Ghearing provides a measured volume for the Kinney KT-170LP
{
SE pump to be 5.3 gallons with the oil overflows in place.
In the subject conference call, USEC stated that the volume of concern is the oil reservoir located above the pump cavity since the pump can only operate with a thin oil film on the internal surfaces of the cavity. During pump operation, oil diffuses from the reservoir to the cavity through a cap gland. Once the pump ceases to operate, the cap gland forms a barrier between the oil reservoir and the pump cavity, thereby ensuring that the only significant UF6/ oil mixture that could occur would be in the reservoir. Based on this new information provided l verbally by USEC, the NRC staff concludes that there is no immediate NCS concern regarding operation of the present day Area 1,2, and 3 SE pumps at PORTS. 1 Docket 70-7002 ,
