13、FunctionThe nuclear auxiliary building ventilation is not a safety related system.During normal operation, the DVN system ventilates charging pump rooms. In case of failure, it must be replaced for this function by the DVH safety related system.System Manual-DVNChapters 2-3-4-5Rev. A 2/453GENERAL DE

14、SIGN3.1 Design bases and safety criteria3.1.1 Design basesThe DVN is a "once-through" all fresh air ventilation system (excepted DEG technical room subsystem). Room air flowrates are calculated by taking into account either the heat gains from equipment and lighting or the minimum air chan

15、ge rate.The DVN system operates continuously.During summer periods the air supply is cooled through cooling coils and, during winter periods, it is heated through heating coils .Two exhaust subsystems are provided: one, for non iodine contaminable rooms (called "normal exhaust") in which t

16、he air is filtered across HEPA filters, and one, for iodine contaminable rooms (called "iodine exhaust") in which the air is filtered across HEPA filters and iodine adsorbers as soon as the iodine concentration rate reaches a preset threshold.When the EBA system operates, the air from the

17、two reactor buildings as well as the air from the nuclear auxiliary building is exhausted either through the HEPA filters alone or the HEPA filters and iodine adsorbers depending on the iodine concentration rate, prior to discharge to the environment via the stack.A smoke removal subsystem is provid
