| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.5.8 states explosive gas and storage tank radioactive monitoring program, Section b., limits the liquid radwaste storage tanks in the low-level radwaste processing and storage facility (LLRPSF) to less than 50 curies. Contrary to this requirement, on February 3, 2009, a radwaste operator discovered that the dose rate at the vicinity of radwaste surge tank IT-088 was elevated. A subsequent sample of IT-088 determined that the tank contained approximately 88 curies of total radioactivity. This exceeded the Technical Specification administrative limit of 50 curies. As a result, the licensee submitted event report (LER No. 2009-002-00) as required by 10 CFR 20.2203(a)(3)(i). On February 3, 2009, ODAM limiting condition for operations 6.1.5 Condition A: quantity of radioactive material in the tanks exceeding the limit, was entered. The actions associated with Condition A required suspension of all additions of radioactive material to IT-088 tank and to reduce tank concentration limits to less than 50 curies within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. On February 4, 2009, the IT-088 tanks radioactivity concentration was reduced below 50 curies in less than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />; subsequently, ODAM OLCO 6.1.5 Condition A was exited. This issue was entered into the licensees corrective action program as CAP 063486. The finding was reviewed using IMC 0609, Appendix D, Public Radiation Safety Significance Determination Process, and was determined to be of very low safety significance. Specifically, the finding was not a radioactive material control or transportation issue and the finding was not indicative of a failure to implement the effluent control program and did not result in a dose to the public greater than 0.005 rem or in excess of the criterion in Appendix I to 10 CFR Part 50 or CFR 20.1301(e) |
