Abstract

905,684. Reactor pressure vessels. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 4, 1961 [July 4, 1960], No. 23258/60. Class 39 (4). Fire suppression in a nuclear reactor is effected by the injection of a fire-suppressing fluid into the fuel channels through the piping system used to monitor the coolant to detect fuel element sheathing failure. The coolant from each channel passes through a detector and then into a common return duct from which it is pumped back into the pressure vessel. A valve 23, Fig. 2, is incorporated in the return duct and comprises an impervious membrane 24 in the form of a bursting disc and a perforated metal support backing 25 at the atmospheric side of 24. A small pressure differential acting from the atmospheric side, i.e. from left to right will fracture disc 24 while the disc, supported by the backing 25 resists the normal pressure within the reactor. If the pressure vessel is ruptured and a fall of internal pressure results, a fuel fire is prevented by the injection of borated water through valve 23 from the atmospheric side, the membrane 24 being broken by the low water pressure.
