EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 140 / 257 FIGURE 49:FUEL ASSEMBLY STORED IN RACK IN REACTOR POOL The storage pools are isolated from the environment by impermeable barriers (e.g. stainless steel liner) and by a ventilation system incorporating high efficiency particulate in air (HEPA) filters. Additional systems are provided to detect any leaks during pool operation. The pools are protected against earthquake damage by neoprene pads which support the pool and isolate it from the building structures. The build-up of heat and radiochemical contaminants within the pool is prevented by the incorporation of heat exchangers and ion exchangers. Both of these are submerged in the pool and together they ensure that optimum conditions are maintained. Locating these facilities within the pools also minimises the infrastructure requirements and the risk of leaks through external pipework.
