  • Patent number: 6931090
    Abstract: All possible loading patterns for a nuclear reactor core are searched and optimized for compliance with design constraints. The fuel inventory is divided into a few batches according to coarse levels of reactivity. A recursive enumeration process identifies patterns meeting selected core position constraints, which can be user modified to adjust the search space size. For the batch loading patterns satisfying the constraints, the batches are divided into several smaller batches. A sensitivity matrix linearizing the relationship between fuel assembly position and the depletion model is processed through mixed integer linear programming with branching and bounding to identify an optimal daughter loading pattern. The process is repeated through several levels of batch refinement and selection of optimal daughter patterns, including a level where burnable absorbers are assigned to feed assemblies, until the individual fuel assembly level is reached.

  • Patent number: 5178543
    Abstract: A trainer, mounted and housed within a mobile console, is used to teach and reinforce fluid principles to students. The system trainer has two centrifugal pumps, each driven by a corresponding two-speed electric motor. The motors are controlled by motor controllers for operating the pumps to circulate the fluid stored within a supply tank through a closed system. The pumps may be connected in series or in parallel. A number of valves are also included within the system to effect different flow paths for the fluid. In addition, temperature and pressure sensing instruments are installed throughout the closed system for measuring the characteristics of the fluid, as it passes through the different valves and pumps. These measurements are indicated on a front panel mounted to the console, as a teaching aid, to allow the students to observe the characteristics of the system.

  • Patent number: 4917611
    Abstract: A training instrument for use in teaching a trainee the proper use of a radioactivity measuring instrument includes a transmitter unit that is held and controlled by an instructor and further includes a receiver unit which is held and operated by the student and which simulates the radioactivity measuring instrument. The instructor selects a level of radioactivity to be measured by the student at a remote site, and that information is transmitted to the receiver unit in a moduated form that is not affected by atmospheric conditions or reflections from surrounding objects. Both the receiver and the transmitter include circuits that simulate the operation of a multirange meter. These circuits employ the most significant bits of a digital representation of the signal to determine which scale should be used, while the remaining digits indicate the magnitude of the signal as read on the selected scale.

  • Patent number: 4828787
    Abstract: The apparatus for simulation of the operation of a pressurized water reactor comprises a reactor vessel with a heater, a steam generating vessel divided into a primary portion and a secondary portion. The reactor vessel and the primary portion of the steam generating vessel are connected in a primary feed loop equipped with a coolant pump, while the secondary portion of the steam generating vessel and the condenser unit are joined together in a secondary feed loop provided with a feed pump. With such an apparatus a steam generating vessel heating pipe break or fracture can be simulated when the reactor vessel and a primary part of an additional steam generating unit are joined in another primary feed loop parallel to the primary feed loop having the cooling pump and a secondary part of the additional steam generating unit is connected with the aid of at least two branch pipes to the secondary feed loop.

  • Patent number: 4699753
    Abstract: The responses of a nuclear reactor refueling machine to commands from a detachable control console are simulated to allow operation of the console for testing and operator training with the console removed from the machine. A simulator, which is connected to the console by the same input and output leads which normally connect the console to the refueling machine, includes a single pulse generator driven by a single three phase A-C motor to simulate movement of the refueling machine bridge, trolley and hoist. The motor drive signals generated on separate console output leads are all connected to the single simulator motor, while the brake release signals energize relays which switch the pulse signals generated by the single pulse generator to the console input leads corresponding to the selected refueling machine component drive motor.

  • Patent number: 4614499
    Abstract: A simulator, for use with stereoradiographs, as a neurosurgical aid in locating potential paths for the implantation of probes in selected locations of the brain. It has a support, on the top surface of which is mounted a pair of radiographs disposed for stereoscopic viewing. An elongated ruler lies over the stereoradiographs and is movable in translation over them. A pair of transparent flat plotting plates are mounted on the ruler and are slidable therealong. Each plotting plate has a circular hole and a transparent circular disc is rotatable around this hole; a radial line extending from the center of the disc giving a "floating line" in the stereoscopically viewed model to simulate a probe to be implanted in the brain.

  • Patent number: 4582491
    Abstract: An apparatus for training a user in contamination surveillance. The contamination may be from a nuclear, bacteriological or chemical explosion or leak, for example. The apparatus is portable and can be carried by the user to various points of an exercise area. The apparatus includes a data store and an interpolation device. The data store stores data which is derived from a mathematical model of an assumed source of contamination and which defines the contamination levels at various locations within the exercise area at respective elapsed times after the assumed commencement of contamination. The interpolation device is responsive to first signals which define the location within the exercise area and to second signals which define the elapsed time when the user of the apparatus inputs the first signals. The apparatus also may include a display on which is shown the contamination level, and a keyboard from which the first and second signals may be input.

  • Patent number: 4500295
    Abstract: A simulated radiation source and a compatible detector system are disclos The combination is useful in training for detecting alpha radiation contamination. A flexible, soft iron plate or first permanent magnet in the detector system responds to a second magnet that is employed to represent an alpha radiation source. Where the first permanent magnet is used, an iron member may be adopted in lieu of the second magnet. The simulated source is affixed to the subject's clothing or body. When the detector system is brought into proximity with the simulated radiation source, the soft plate or first magnet responds and affects a strain gage which in turn provides an electronic indication.

An enclosed space, including the source of ionizing radiation is separated into three spaces, each space separated from the adjacent space by a gas impermeable, radiation permeable barrier. A guided wave structure, pulsed with high voltage pulses in conjunction with the firing of the source of ionization radiation is disposed adjacent to the barrier separating two of the spaces. A gas handling system is provided to introduce a selected non-ionizing gas and a selected ionizing gas into the spaces on either side of the barrier adjacent to the guided wave structure.
