SUBJECT:
NRC's Staff Review of NASA's Survey Plan and Sampling Results of the Contamination at the Plum Brook Reactor Facility.
Dear Dr. Earls:
This letter provides the findings of the NRC's staff related to your submittal, dated December 19and 29, 2005, via email, of the survey plan and preliminary results of the sampling of onsite and off-site contamination at the Plum Brook Reactor Facility. The staff notes that NASA has takena phased approach to the soil sampling, employing the recommendations in the Multi Agency Radiation Survey and Site Investigation Manual (MARSSIM) to design surveys and analyze the survey results. The staff has arranged for an in-process, independent evaluation of the NASA's survey methodology by Oak Ridge Associated Universities, and the results of this evaluation will be shared with NASA once it is completed. At the present time, the NRCunderstands that sampling and radiological analysis of creek bed soil are on hold due to freezing temperatures. The staff also notes that, so far, most of the areas sampled are at or only slightly abovebackground radiation levels and show little or no contamination. However, the identified hot spots need further evaluation to determine whether remediation is required. Additionally,biological samples taken from the deer harvest this Fall in nearby areas did not reveal any bio-accumulation of known radio-nuclides from past reactor operations at the site. Therefore, the staff finds that the decommissioning activities at the Plum Brook Site areconducted in accordance with the NRC approved Decommissioning Plan and NRC regulatoryrequirements. Furthermore, all available radiological data indicates that there is presently no safety hazards to site personnel or the members of the public in areas adjacent to the contaminated sections of Plum Brook. Currently, we find your actions to be acceptable and no response to this letter is required.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and itsenclosure will be available electronically for public inspection in the NRC Public DocumentRoom or from the Publicly Available Records (PARS) component of NRC's document system(ADAMS).
