Hydro-pneumatic apparatus for changing critical configuration of nuclear fuel mass

Claim 1

IN COMBINATION WITH A HYDRO-PNEUMATIC DEVICE THAT HOLDS A HYDRAULIC FLUID UNDER PRESSURE FOR PRESSURIZING A GAS FOR HOLDING A NUCLEAR FUEL MASS IN A CRITICAL CONFIGURATION, A PILOT VALVE FOR EXPLOSIVELY RELEASING SAID HYDRAULIC FLUID QUICKLY TO PERMIT SAID GAS TO EXPAND TO SEPARATE SAID NUCLEAR FUEL MASS INTO EQUAL NONCRITICAL CONFIGURATION, COMPRISING A PLURALITY OF PLUNGERS THAT ARE LOADED ACROSS SAID PLUNGERS FOR PREVENTING THE RELEASE OF SAID HYDRAULIC FLUID HAVING MEANS FOR RAPIDLY PRODUCING A LARGE PRESSURE DIFFERENTIAL ACROSS SAID PLUNGERS FOR BIASING SAID PLUNGERS EXPLOSIVELY TO RELEASE SAID FLUID UNDER PRESSURE, AND MEANS FOR DIRECTING SAID EXPLODING FLUID IN A PLURALITY OF STREAMS TO REDUCE IMPEDANCE TO SAID RELEASE WHILE SHAPING SAID FLOW TO PREVENT SHOCK WAVES FROM FLOW INTERFERENCE WHEREBY SAID FUEL MASS IS SEPARATED IN A SHORT TIME TO PREVENT A FATAL BUILDUP OF CRITICALITY.
