Results The licensee maintains three HPG detectors in the radiochemistry counting room and two HPG detectors in the radwaste laboratory.
All-five detectors are used for routine isotopic analysis of radioactive samples to demonstrate compliance with TS and regulatory requirements.
At the time of the inspection the two HPG detectors in the radwaste laboratory and one HPG detector in the radiochemistry counting room were out-of service.
The two in-service HPG detectors were cross-checked on selected count!ag geometries.
The HPG detector labeled (1) is maintained by the C/RS and the HPG detector labeled (2) is maintained by the health physics section.
The analytical results from the two detectors were compared with the NRC results, as well as with each other.
The licensee performed the tritium sample analysis on their liquid scintillation counting system.
The individual sample analyses and comparison of analytical results of the confirmatory measurements are tabulated in Attachment 2.
The licensee's gamma isotopic results from the listed samples in Attachment 2 showed 94 percent agreement with the NRC analysis results based on 58 agreement results out of 62 nuclides identified and compared.
The licensee's tritium result on the NRC tritium sample was in agreement with the NRC analysis result.
The licensee's results cross-checked with 100 percent agreement between the two HPG detectors for all counting geometries compared.
Confirmatory measurements were performed by the licensee on a liquid unknown sample prepared by Radiological Environmental Sciences Laboratory using known nuclide concentrations of sosp, soSr, tritium, and gamma emitting nuclides.
The licensee analyzed the sample and reported the results as requested.
The licensee's analytical results were compared to the known sample activities and t he results of the comparisons are presented in Attachment 2, sample 11.
