Abstract: An improved high energy-density battery for producing continuous low-voltage electrical energy is powered by direct conversion of the kinetic energy of charged particles to electrical potentials. An improved battery comprises at least one primary energy source (20) and a plurality of cells, each cell comprising a secondary electron emitter plate (30, 30') spaced apart from a collector plate (40, 40'). Cells are configured to maximize the number of relatively low-energy secondary electrons from the emitter plates which reaches and is retained by collector plates. Heat production is minimized during efficient energy conversion of the relatively high-energy of primary charged particles to the lower energy but relatively high current capacity of large numbers of secondary electrons. Material work functions and Fermi levels of the emitters and the collectors are chosen to favor emission of secondary electrons from emitter plates and retention of secondary electrons impinging on a collector plate, thus increasing efficiency and reducing internal battery leakage currents. Relatively low cell voltages and low heat losses in the direct conversion process mean that the energy sources may be confined in relatively small packages suitable for powering, and mounting in close proximity to, electronic microcircuits and sensors.

Abstract: The invention concerns an emergency cooling arrangement for a nuclear reactor plant, the arrangement comprising a safety container (10) housing a pressurized reactor container (2) which comprises a reactor core (3). A flood pipe (4, 4a) is provided which has an outlet opening (6, 6a) which is disposed in or on the pressurized reactor container (2) and is closed by a passively opening closure element (5, 5a). The closure element (5, 5a) opens the outlet opening (6, 6a) when a limiting temperature is exceeded. For this purpose, the closure element (5, 5a) preferably comprises a safety fuse (27) which melts at approximately 900 DEG C. The flood pipe (4, 4a) is connected to a flooding container (8) disposed geodetically above the reactor core (3), whereby coolant (11) is fed by gravity into the pressurized reactor container (2). In order to ensure that the flood pipe (4, 4a) is not triggered spuriously, it comprises outside the pressurized reactor container (2) an additional closure element (16) which closes the flood pipe (4, 4a) during normal operation and opens the flood pipe (4, 4a) in the event of a malfunction, when the temperature in the pressurized reactor container (2) increases drastically but is lower than that of the closure element (5, 5a), in particular approximately 500 DEG C. The invention further concerns a process for the emergency cooling of a reactor core (3) by means of a flood pipe (4, 4a) which is closed by a passively opening closure element (5, 5a).

Abstract: A method for supervision of a neutron flux detector in a nuclear reactor comprising a plurality of neutron flux detectors. During a learning phase, connection weights of a neural network are determined, which network comprises at least one input layer (31) and one output layer (33). The input layer comprises a number of processing elements adapted to receive a number of input signals (S(t) - S(t-49 DELTA t)), and the output layer comprises a number of process elements adapted to deliver a number of state signals (N1, N2, N3, N4). The determination of the connection weights is done by supplying to the network a plurality of sets of input signals with known state signals, by comparing the state signals calculated by the network with the known state signals, and by successively correcting the connection weights to reduce the deviation between the known and the calculated state signals. During a supervision phase the neural network is supplied with input signals corresponding to measured values at different times from the supervised detector, and based on the connection weights determined during the learning phase, the state signals are calculated. In dependence of the calculated state signals and the state signals of a number of selected reference detectors, it is determined whether the detector is defective.
