Abstract
Abstract In a system for monitoring and displaying those operating parameters of a nuclear reactor which pertain to the core power distribution, an incore system of detectors (24) provides power peaking data to a power peaking margin display system (16) which determines an operational limit line for the reactor core. The positions of the axial power shaping rods and the regulating rods are determined (22) and are shown graphically by means of a cursor on a visual display (18) on which is superimposed the operational limit line determined by the power peaking margin system (16).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
A system for monitoring operating conditions within a nuclear reactor, the system (10) being characterised by means (24) for measuring a plurality of operating parameters within the nuclear reactor, means (16) for determining from said operating parameters the operating limits before a power peaking condition exists within the nuclear reactor, and means for displaying said operating limits, the means for displaying comprising a visual display (18) permitting continuous monitoring of the operating conditions within the nuclear reactor.
Claim 2
Independent Claim
77 words
A system for monitoring operating conditions within a nuclear reactor, the system (10) being characterised by means (24) for measuring a plurality of operating parameters within the nuclear reactor, means (16) for determining from said operating parameters the operating limits before a power peaking condition exists within the nuclear reactor, and means for displaying said operating limits, the means for displaying comprising a visual display (18) permitting continuous monitoring of the operating conditions within the nuclear reactor.
Claim 3
Dependent Claim
50 words
A system according to claim 1, including means (26) for measuring the amount of output power being produced by the nuclear reactor, said output power amount being utilized by the determining means (16) to adjust said operating limits in response to changes in the output power of the nuclear reactor.
Claim 4
Dependent Claim
37 words
A system according to claim 1 or claim 2, including means (22) for determining the position of regulating rods within the nuclear reactor, the regulation rod position being displayed on one axis of the visual display (18).
Claim 5
Dependent Claim
43 words
A system according to claim 1, claim 2 or claim 3, including means (22) for determining the position of axial power shaping rods within the nuclear reactor, the axial power shaping rod position being displayed along an axis of the visual display (18).
Claim 6
Independent Claim
28 words
A system according to any one of the preceding claims, including cursor means for indicating the present operating conditions of the nuclear reactor on the visual display (18).
Claim 7
Independent Claim
32 words
A system according to any one of the preceding claims, including memory means (54) for the storage of pixel sets utilized to visually define said operating limits on the visual display (18).
