| Title | Spent Fuel Pool Securement of Irradiated Local Power Range Monitors |
| Description | During inspection activities associated with the storage and securement of irradiated materials within the spent fuel pool, the inspectors identified a URI associated with the securement of irradiated Local Power Range Monitors (LPRMs) within the spent fuel pool.2
The inspectors observed a series of locked metal sleeves attached to a handrail surrounding the spent fuel pool. These locked metal sleeves extend into the spent fuel pool. From each of these sleeves were suspended two or three irradiated LPRMs. These metal sleeves had the potential to rotate at the point of securement to the handrail. This rotation would increase the possibility of an individual obtaining access to the irradiated LPRMs. The inspectors discussed this concern, along with the potential radiation exposure rates on the irradiated LPRMs, with the licensee. Specifically, the NRC provides guidance on this subject in Regulatory Guide 8.38, Controls of Access to High and Very High Radiation Areas in Nuclear Power Plants, Revision 1. Section 4.2, Spent Fuel Pools, Reactor Vessels, and Refueling Cavities, provides the following in part, "Therefore, these pool areas do not have to be controlled as high or very high radiation areas solely because of the materials in them, provided that the following criteria are fulfilled: Control measures are implemented to ensure that activated materials are not raised above or brought near the surface of the pool water." The licensee could not immediately provide the specifics about the design of the locked metal sleeves and the associated LPRM radiation exposure rates to answer inspecto questions. The licensee installed an additional metal bar to prevent rotation of the meta sleeves after this issue was identified by the inspectors. The inspectors could not evaluate whether the controls as originally implemented were adequate to prevent activated materials from being raised above or brought near the surface of the pool water. Consequently, this issue remains under review by the NRC to determine if it represents a performance deficiency and is categorized as a URI (URI 05000341/2014005-03, Spent Fuel Pool Securement of Irradiated LPRMs). |
