Section 180-19-013 - IRRADIATOR POOLS013.01SPECIFICATIONS. For licenses initially issued after October 30, 1996, irradiators pools must either: (A) Have a water-tight stainless steel liner or a liner metallurgically compatible with other components in the pools; or(B) Be constructed so there is a low likelihood of substantial leakage and have a surface designed to facilitate decontamination. In either case, the licensee must have a method to safely store the sources during repairs of the pool.013.02WATER OUTLETS. For licenses initially issued after October 30, 1996, irradiator pools must have no outlets more than 0.5 meter below the normal low water level that could allow water to drain out of the pool. Pipes with intakes more than 0.5 meter below the normal low water level and could act as siphons must have siphon breakers to prevent the siphoning of pool water.013.03REPLENISHMENT. A means must be provided to replenish water losses from the pool.013.04VISIBLE INDICATOR. A visible indicator must be provided in a clearly visible location to indicate if the pool water level is below the normal low water level or above the normal high water level.013.05WATER PURITY. Irradiator pools must be equipped with a purification system designed to be capable of maintaining the water during normal operation at a conductivity of 20 microsiemens (ohms) per centimeter or less and with a clarity so the sources can be seen clearly.013.06PHYSICAL BARRIER. A physical barrier, such as a railing or cover, must be used around or over irradiator pools during normal operation to prevent personnel from accidentally falling into the pool. The barrier may be removed during maintenance, inspection, and service operations.013.07TOOLS. If long-handled tools or poles are used in irradiator pools, the radiation dose rate on the handling areas of the tools may not exceed 0.02 millisievert (2 millirems) per hour.180 Neb. Admin.
