G21C9/027 - CPC Classification

Classification description:

Emergency protection arrangements structurally associated with the reactor, e.g. safety valves provided with pressure equalisation devices; Means for effecting very rapid reduction of the reactivity factor under fault conditions, e.g. reactor fuse; Control elements having arrangements activated in an emergency by fast movement of a solid, e.g. pebbles
