| ENS 57162 | 5 June 2024 16:06:00 | The following information was provided by the licensee via phone and email: This concurrent report is being made because a HEPA filter on a scrap recovery line had degraded below the efficiency that would allow it to remain in service (76.85 percent versus 99.95 percent). This condition is reportable to the Washington Department of Health in accordance with Radioactive Air Emissions License (RAEL) 038. The scrap recovery line has been shut down pending further investigation into the cause of the loss of filter efficiency. Investigation has revealed that no limits were exceeded and no additional reporting is required. |
| ENS 57116 | 9 May 2024 12:57:00 | The following information was provided by the licensee via phone and email: In accordance with 10 CFR 70, Appendix A(c) concurrent reporting, this notification is being made because a plant condition required reporting to the Washington State Department of Health (WDOH). At approximately 1015 PDT on 5/7/2024, three items were found in a storage area. Those items were: 1. A metal table that had been used in contaminated areas. 2. A cart that had been used in contaminated areas to transport material, with an additional weight standard stored on it. 3. An out-of-service overpack, designed to transport pellet sintering boats between buildings. The items were removed and sent to an outside waste area for gamma spectrometry measurement. The gamma spectrometry results at 1445 PDT on 5/7/2024, indicated that less than 8 grams of uranium were present in the transfer vault. This is more than the annual portion quantity of the building containing the storage area. The limit per stack license for Emission Unit 1511 is 1 gram of uranium. The other items were found to not be contaminated. There was no removable contamination on the items as measured by health and safety technicians. |
