Event Description | The following information was provided by Framatome ANP Richland via email:
On December 20, 2021, at 0920 PST, Framatome received notification that a sealed source, which had been removed by a waste broker (Qal-Tek), had failed a leak test. The source, an acrylic rod type made in June 1986 and containing at that time 5 mCi of Cs-137, had been stored at Framatome in a shielding pig for many years. Leak tests had been performed on the storage pig as required by Framatome's radioactive materials license, most recently on November 12, 2021. The waste broker performed a confirmatory leak test on the storage pig on November 22, 2021 and removed the source from the Framatome site. All leak tests performed by Framatome and the waste broker indicated that there was less than 0.005 microcurie of removable contamination on the outside of the storage pig. The source was removed from its storage pig at the waste broker's facility in a controlled environment at which point a sample of the bare source indicated a removable beta activity of 0.015 microcurie. Upon discovering the leak, the waste broker placed the leaking source in a sealed container and decontaminated the inside of the storage pig. The source will be sealed with epoxy to prevent any further leak; being already in the waste stream, no further issue is anticipated from the source. This report is furnished to the NRC, concurrent to one sent to the Washington Department of Public Health. The licensee has notified the State and NRC Region IV.
The following information is a synopsis of information received from the Washington State Department of Health, Office of Radiation Protection (Agency) via e-mail and phone: The Agency was notified of this event yesterday as it is stated above with the following additional information. The Washington State license for Framatone, Inc. is WN-I0612, Qal-Tek Associates, LLC NRC license is 11-27610-01, cesium-137 source current activity is about 0.0022 curies (2.2 millicuries). The Agency submitted an NRC NMED report for this event yesterday. The Agency was determining if the event met reporting requirements for notification of the NRC Headquarters Operations Center (HOC). Today the Agency determined this event was reportable to the NRC HOC as an Agreement State report since it met the criteria of 10 CFR 30.50(b)(2). Washington state incident number WA-21-026 Notified R4DO (O'Keefe), and NMSS Events Notification group (email). |
