Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 211 words
The nuclear power plant having a pressurized water reactor connected in a primary circulatory loop wherein a pump is also connected for circulating a coolant therein, an electromagnetic filter device having an inlet and an outlet and connected by said inlet and said outlet in direct shunt with a portion of the primary circulatory loop so that a portion of the coolant is passed therethrough and nuclear waste contained in the coolant is filtered-out therein, an inlet valve and an outlet valve respectively connected to said inlet and said outlet of said filter device and, in turn, connecting said filter device in parallel with the primary circulatory loop, a rinsing line and a waste line for said filter device, a rinsing line valve connecting said inlet of said filter device to said rinsing line, and a waste line valve connecting said outlet of said filter device to said waste line, said inlet and said outlet valves being closable so as to discontinue the flow of coolant through said electromagnetic filter device from said primary circulatory loop, and said rinsing line valve and said waste line valve being openable so as to flush accumulated waste out of said filter device independently of the continued circulation of coolant in the primary circulatory loop.
Claim 2
Dependent Claim 211 words
The nuclear power plant having a pressurized water reactor connected in a primary circulatory loop wherein a pump is also connected for circulating a coolant therein, an electromagnetic filter device having an inlet and an outlet and connected by said inlet and said outlet in direct shunt with a portion of the primary circulatory loop so that a portion of the coolant is passed therethrough and nuclear waste contained in the coolant is filtered-out therein, an inlet valve and an outlet valve respectively connected to said inlet and said outlet of said filter device and, in turn, connecting said filter device in parallel with the primary circulatory loop, a rinsing line and a waste line for said filter device, a rinsing line valve connecting said inlet of said filter device to said rinsing line, and a waste line valve connecting said outlet of said filter device to said waste line, said inlet and said outlet valves being closable so as to discontinue the flow of coolant through said electromagnetic filter device from said primary circulatory loop, and said rinsing line valve and said waste line valve being openable so as to flush accumulated waste out of said filter device independently of the continued circulation of coolant in the primary circulatory loop.
