Attachment SAFETY EVALUATION BY THE EMERGENCY PREPAREDNESS AND RADIATION PROTECTION BRANCH OFFICE OF NUCLEAR REACTOR REGULATION WISCONSIN PUBLIC SERVICE CORPORATION KEWAUNEE NUCLEAR POWER PLANT DOCKET NO. 50-305 1.0 Introduction By letter dated October 17, 1995, as supplemented on November 3, 1995, Wisconsin Public Service Corporation (the licensee) requested approval for the onsite disposal of contaminated sewage sludge similar to a previous disposal request that was approved by the NRC on June 17, 1992.
2.0
Background
In a letter dated September 12, 1989, the licensee requested authorization for the alternate disposal of very-low-level radioactive material.
In a Safety Evaluation (SE) dated June 17, 1992, the NRC approved the licensee's request pursuant to 10 CFR 20.302 (new 10 CFR 20.2002) for the disposal of 15,000 cubic feet of contaminated waste sludge by land application at the Kewaunee Nuclear Power Plant (KNPP) location.
The SE imposed the following boundary conditions:
- 1. The annual disposal must be less than a total activity of 0.2 mCi.
- 2. The whole body dose to the hypothetical maximally exposed individual must be less than 0.1 mrem/year.
- 3. The disposal must be at the same site.
The licensee completed the disposal of the contaminated waste sludge discussed in the SE dated June 17, 1992.
The licensee is now requesting authorization to di:;pose of additional contaminated waste sludge within the boundary conditions of the previously approved disposal.
3.0 Evaluation The licensee has proposed to dispose of approximately 6000 gallons (800 cubic feet) of sewage sludge similar to the material approved for disposal in the SE dated June 17, 1992. The principal radionuclides identified in the waste sludge and their activity based on measurements in May, 1995 are:
Co-58, 0.0009 mCi; Co-60, 0.0008 mCi; and Cr-51, 0.0006 mCi. The total combined activity is 0.0023 mCi. This activity is well below the boundary value of 0.2 mCi.
Additionally, Cr-51 with it short half-life (27.7 day) will have undergone significant decay from its initial value of 0.0006 mCi.
The licensee has committed that the new disposal will meet all the radiological boundary conditions, on a cumulative basis, contained in the SE for the 10 CFR 20.302 application approved on June 17, 1992. Additionally, the 'licensee has stated that all applicable permits for this disposal have been obtained from the Wisconsin Department of Natural Resources.
4.0 Conclusion The staff finds the licensee's proposal to dispose of the low-level radioactive waste sludge pursuant to 10 CFR 20.2002, on the licensee's site, is within the radiological boundary conditions approved in the June 17, 1992 SER find is therefore acceptable.
The licensee is required to permanently incorporate Offsite Dose Calculation Manual as an Appendix, and of this commitment be reported to the NRC.
