Safety arrangement for neutronic reactors aboard water-sustained craft

Claim 1

A SAFETY SYSTEM FOR NEUTRONIC REACTOR ABOARD WATER-SUSTAINED VESSELS, COMPRISING A SHIELD FOR A NEUTRONIC REACTOR DISPOSED WITHIN A VESSEL IN SUSTAINING WATER, A FLUID-TIGHT COMPARTMENT WITHIN SAID SHIELD DEFINED BY A WALL AND CONTAINING THE REACTOR, SAID WALL BEING SPACED FROM THE SHIELD TO DEFINED A WATER CHANNEL DISPOSED BELOW THE LEVEL OF THE SUSTAINING WATER, AND CONDUIT MEANS HAVING INLETS COMMUNICATING WITH THE WATER CHANNEL AT A PLURALITY OF POINTS THEREOF AND HAVING OUTLETS FOR COMMUNICATING WITH SUSTAINING WATER EXTERIOR OF A VESSEL ALONG AT A PLURALITY OF POINTS THEREOF, SAID CONDUIT MEANS BEING SO DISPOSED IN SAID VESSELS THAT ONE OUTLET IS AT AN ELEVATION ABOVE ANOTHER OUTLET WITH BOTH OUTLERS PERMITTING PASSAGE OF WATER THERETHROUGH REGARDLESS OF THE POSISTION OF THE VESSEL IN THE SUSTAINING WATER, WHEREBY DECAY HEAT LIBERATED BY REACTOT FUEL AFTER REACTOR SHUST-DOWN CAUSES A NATURAL CIRCULATION OF WATER THROUGH SAID WATER CHANNEL AND SAID MENTIONED INLETS AND OUTLATS OF THE CONDUIT MEANS TO REMOVE THE DECAY HEAT FROM THE COMPARTMENT.
