Docket No. 50-312 MEMORANDUM FOR: File, Docket No. 50-312 FROM: G. P. Yubas, Ch%f Emergency9 . raparedness & Radiological Protection Branch
SUBJECT:
MEETING WITH REPRESENTATIVES OF SACRAMENTO MUNICIPAL UTILITY' DISTRICT (SMUD) TO DISCUSS THE LICENSEE'S ACTIONS REGARDING THE P0TENTIAL RELEASE OF CONTAMINATED RESIN IN THE LIQUID EFFLUENT WASTE STREAM DURING JANUARY 15-19, 1989 On Wednesday, February 1,1989, members of the Region V staff and SMUD met at 10:00 A.M., in the Chief, Emergency Preparedness & Radiological Protection l Branch's office, to discuss actions'taken and those planned to determine if any resin was released offsite, the source of the resin, the cause of the incident, and corrective measures to prevent recurrence. This meeting was requested by the licensee.
NRC Attendees: G. P. Yuhas, Chief Emergency Preparedness & Radiological Protection Branch H. S. North, Acting Chief, Facilities Radiological Protection Section C. A. Hooker, Radiation Specialist SMUD Attendees: S. P. Melancon, Project Manager S. Crunk, Manager, Nuclear Licensing-The agenda addressed at the meeting is included in the attachment.
Mr. Melancon discussed the scope of the actions taken, those in progress, and those proposed to address concerns associated with the release of contaminated resins from the "B" Regenerate Holdup Tank to the North retention basin. The items discussed are also contained in the attachment.
Mr. Yuhas requested that the licensee keep the Region V office abreast of the
, results from Lawrence Livermore National Laboratory's stream bed surveys, sample analysis data from the RHUT discharge filters, and sample analysis data from the condensate polisher sump. Mr. Melancon' acknowledged the request.

6.
LLNL IS CONDUCTING ENVIRONMENTAL SURVEYS DOWNSTREAM OF THE RETENTION BASIN DISCHARGE. SEVEN (7) WATER SAMPLES AND FOURTEEN (14) SEDIMENT SAMPLES WERE TAKEN. (PRELIMINARY RESULTS FROM THE ANALYSIS OF THE WATER SAMPLES SHOWED NO EVIDENCE OF RESIN. PRELIMINARY SEDIMENT ANALYSES REVEALED THE PRESENCE OF RESIN IN TWO SAMPLES.)
THE PHYSICAL ORIENTATION OF THE INLET TO A RETENTION BASIN AND THE DISCHARGE POINT, THE MECHANICS OF RETENTION BASIN OPERATION, THE BEHAVIOR OF RESIN IN WATER AND THE LOCATION OF THE RESIN DISCOVERED IN THE NORTH RETENTION INDICATE THAT RESIN WAS PROBABLY NOT RELEASED OFFSITE.
DISCHARGE OF BASIN THROUGH STRAINER INDICATED NO RESIN.
