    摘要： A method whereby signals that are output by replacement SPNDs are converted into equivalent signals that would have been detected by legacy SPNDs for input to the legacy software. The replacement SPNDs have a different geometry than the legacy SPNDs and also have a different neutron sensitivity than the legacy SPNDs. The replacement SPNDs are subjected to a neutron flux in a core of a reactor and responsively output a set of signals. The set of signals and the geometry of the replacement SPNDs are employed to create a characterization of the neutron flux in the form of a curve that represents flux as a function of location along the core of the reactor. The legacy geometry of the legacy SPNDs is then employed to find the values on the curve that correspond with the positions where the legacy SPNDs had been located to create inputs for the legacy software.

    摘要： A method regulates operating parameters comprising at least the mean temperature of the core (Tm), and the axial power (AO) imbalance.The method includes development of a vector (Us) of control values of the nuclear reactor by a supervisor (31) implementing a predictive control algorithm; development of a vector (uK) of corrective values of the nuclear reactor controls by a regulator (33) implementing a sequenced gain control algorithm; development of a vector (U) of corrected values of the commands of the nuclear reactor, by using the vector (US) of the values of the commands produced by the supervisor (31) and the vector (UK) of the corrective values of the commands produced by the regulator (33); and regulation of the operating parameters of the nuclear reactor, by controlling actuators using the vector (U) of the corrected values of the controls.

    摘要： Disclosed herein is a method of synthesizing nuclear reactor power distribution using an optimized nonlinear basis function by means of combining signals of neutron detectors provided inside or outside a nuclear reactor. The method includes searching an optimized basis function combination, without determining previously a shape of a basis function, in such a way that error occurrence is minimized, and determining a shape of a synthesis function. When searching the optimized basis function combination and determining the shape of the synthesis function, the following equation is used. FZ  ( Z i ) = a 0 + ∑ i = 1 n  a i  φ i + ∑ i = 1 n  ∑ j = 1 n  a ij  φ i  φ j + ∑ i = 1 n  ∑ j = 1 n  ∑ k = 1 n  a ijk  φ i  φ j  φ k + … (here, FZ(Zi): a power distribution value at position Zi, Φi, Φj, Φk: signals of detectors at respective positions).

    摘要： A method for producing energy from a nuclear fuel material contained in an enclosure, through a process of breeding of a fissile element from a fertile element of the fuel material via a .beta.-precursor of the fissile element and fission of the fissile element. A high energy particle beam is directed into the enclosure for interacting with heavy nuclei contained in the enclosure so as to produce high energy spallation neutrons. The neutrons thereby produced are multiplied in steady sub-critical conditions by the breeding and fission process. The breeding and fission process is carried out inside the enclosure.
