TELEPHONE CONFERENCE WITH SIEMENS POWER CORPORATION (SPC) ON THE UNRESTRICTED 3 i

RELEASE OF AMMONIUM HYDROXIDE / AMMONIUM NITRATE SOLUTION (TAC NO L31208)

On August 10,1999, a conference call between Nuclear Regulatory Commission (NRC) and Siemens Power Corporation (SPC) was condrJed to discuss an amendment request to authorize the unrestricted release of ammonium hydroxide / ammonium nitrate solution for commercial use. The following NRC staff were involved; Paul Lain, Julie Olivier, and Don Stout.

The licensee had Loren Maas, Jim Edgar, Sid Koegler, and Rich Burklin in attendance. The following was discussed: process hazards analysis, ion exchange columns, new equipment, concentrations, venting, and uranium content.

]

SPC says this activity is covered under the overall process hazards analysb for the ADU and MURS processes. The liquid effluent streams will be run through the existing lon etchange column and a new polishing column being installed within the UO2 building. lon exchange columns will be regenerated with a carbonate wash followed by an acid wash. Two new storage tanks for this solution will be installed near the existing HF acid tanks.' The flow rate will be between 1.5 and 6 gpm depending on the process. SPC says the effluent is approximately 10 percent arnmonium hydroxide,5 percent ammonium nitrate and 85 percent water. SPC l- says that since this solution is not processed through the Ammonium Recovery Facility, the uranium content will be higher than the ammonium hydroxide solution which was previously authorized for unrestricted release. Uranium content of the ammonium hydroxide / ammonium nitrate solution will be 1.0 ppm compared with the ammonium hydroxide solution at 0.05 ppm.

SPC comments that the uranium concentration is still well below NRC guidance for free )
