Abstract
A high-temperature gas cooled nuclear reactor system comprises a containment building, a concrete reactor pressure vessel inside the containment building, and a safety relief valve connected to the concrete reactor pressure vessel. The spring of the safety valve consists of a material with a spring constant decreasing as temperature rises. A heat exchanger is provided in close proximity to cool the spring of the safety valve which is subject to the heat of the reactor coolant escaping when the safety valve is open. The heat exchanger of the safety valve is connected to a liner cooling system of the concrete reactor pressure vessel.
Claims13
A nuclear reactor, in particular a high-temperature reactor, with a reactor protecting building and therein a reactor pressure container in particular made of concrete, which is provided with at least one valve designed as a spring valve to limit the pressure in the reactor pressure container in the event of nuclear reactor overheating and which is provided with a liner on its inside and associated with cooling ducts communicating with at least one liner cooling equipment,
- characterized in that the valve spring (44) of a valve 38 consists of a material with a spring constant decreasing as the temperature rises and is subject to the heat of the gas flowing out when the valve 38 is open and that at least one cooling apparatus (25) is provided to cool at least one of the valve spring (44) and the gas before if flows out, said apparatus being connected to at least one liner cooling equipment (12, 13).
