Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
33 words
A LOW POWER NUCLEAR REACTOR CORE FORMED OF A HOMOGENEOUS MIXTURE OF POLYETHYLENE AND U 235 ENRICHED UO2 PARTICLES HAVING A DIAMETER OF 10-30 MICRONS, SAID POLYETHYLENE BEING PRE-IRRADIATED TO ABOUT 3 MEGAREP.
Claim 2
Dependent Claim
33 words
A LOW POWER NUCLEAR REACTOR CORE FORMED OF A HOMOGENEOUS MIXTURE OF POLYETHYLENE AND U 235 ENRICHED UO2 PARTICLES HAVING A DIAMETER OF 10-30 MICRONS, SAID POLYETHYLENE BEING PRE-IRRADIATED TO ABOUT 3 MEGAREP.
Claim 3
Dependent Claim
149 words
A CORE ASSEMBLY FOR A LOW POWER NUCLEAR REACTOR COMPRISING A FLUID TIGHT CORE TANK, A HORIZONTALLY EXTENDING THIN PARTITION MEMBER DISPOSED THEREIN DIVIDING SAID TANK INTO UPPER AND LOWER CHAMBERS, A SOLID FORM HYDROGEN MODERATED UO2 CORE DISPOSED IN SAID TANK, SAID CORE HAVING A FIRST SUB-CRITCAL MASS PORTION DISPOSED ABOVE SAID PARTITION MEMBER AND SUPPORTED THEREBY AND HAVING A SECOND SUB-CRITICAL MASS PORTION DISPOSED BENEATH SAID PARTITION MEMBER, MEANS SUPPORTED BY SAID TANK AND DISPOSED WITHIN SAID LOWER CHAMBER OPERABLE TO HOLD SAID SECOND CORE PORTION AGAINST SAID PARTITION MEMBER IN REACTIVE RELATION WITH SAID FIRST CORE PORTION, SAID MEANS INCLUDING A HEAT RESPONSIVE MEMBER DISPOSED WITHIN SAID CORE OPERABLE IN RESPONSE TO A PREDETERMINED INCREASE IN TEMPERATURE OF SAID CORE TO RELEASE SAIC SECOND CORE PORTION AND ALLOW THE SAME TO DROP DOWNWARDLY WITHIN SAID LOWER CHAMBER OUT OF REACTIVE RELATION WITH SAID FIRST CORE POTION.
Claim 4
Dependent Claim
