Title | Surveillance Not Performed in Required Timeframe |
Event Description | The [Missouri University of Science and Technology Reactor] MSTR is required by Technical Specification 4.6.2(1) to perform an experimental verification of calculated airborne effluent release values every five years and when a change in licensed power occurs. An experimental verification was performed on October 24, 2019. However, in a follow-up assessment of the verification report and data, the results and analysis were determined to be non-credible. As the most recent experimental verification was completed on October 27, 2014, the MSTR does not meet the requirement of TS 4.6.2(1).
This report is being made under the provisions of MSTR Technical Specification 6.7.2, requiring a report by telephone to the NRC Headquarters Operations Center no later than the following working day (reported as EN-55266). Under the provisions of MSTR Technical Specification 6.7.2, a written follow-up report will be submitted to the Commission within 14 days. An experimental verification of gaseous effluent release will be performed as soon as practical following restoring the MSTR to an operable status, which is expected to occur no later than July 31, 2021. The licensee will notify the NRC PM (W. Kennedy). |
