Title: Monitoring method for noncritical nuclear fuel
Inventor: SUZAKI TAKENORI
IPC: G21G4/00
Filed: 1992-09-11
Abstract: PURPOSE:To detect abnormal approach by nuclear fuel to its criticality by periodically fluctuating a neutron source in the specified direction within a specified range in the inside of a store tank containing nuclear fuel and the like, or in its circumference, measuring the change in a counting rate with time by a neutron detector, computing its average value and fluctuation amplitude around the value by a specified formula, and thereby monitoring a ratio of the aforesaid computed value to the average value. CONSTITUTION:A neutron source 2 is provided over the center axial line of a cylindrical fuel tank 1, and it is oscillated in a range of 5cm in the axial direction at a period of about 1 second. A neutron detector 3 is disposed at the periphery of the fuel tank 1. Fuel is formed by mixing uranium concentrated by about 3% with water in such a way that a ratio of the number of hydrogen atoms to the number of uranium atoms is roughly 6. Now, the change in a counting rate C with time is measured by the detector 3, an average value Co and the fluctuation amplitude A of a counting rate are obtained by the use of a formula: C=Co+ASint/T, and A/Co is then determined. In the formula, t represents time elapsed, and T represents the fluctuation period of the position of the neutron source 2. When a ratio of A/ C is monitored, abnormal approach to criticality can thereby be detected.

Abstract: PURPOSE:To make a potting case easy to use and improve the reliability and profitability by constituting a connector made of a flexible material and formed with opening sections above and below and provided with notches for fitting multiple cables on the outer periphery. CONSTITUTION:A potting case 11 made of a flexible material has a large opening 12 at the lower section in addition to an opening at the upper section and is formed with three notches 13-12 on the outer periphery. The case 11 is placed on a Teflon plate 18, cables 16 and 17 are connected and set on the notches 13 and 14, then a potting material 19 is filled, and the cables 16 and 17 are potted. If large bubbles enter the case when the potting material 19 is filled, the case 11 is slightly floated from the Teflon plate to release the bubbles through the opening section 12 on the bottom. Whether the cable connection section is displaced or not from the opening section 12 to the bottom is confirmed. After the potting material is hardened, the case 11 is separated from the plate 18 and stored in an underwater sensor as it is.

Abstract: PURPOSE:To prevent the incidence of reflected light from a sample into an optical fiber again, by arranging an end face of the optical fiber for introducing a measuring light to a sensor for measuring a sample askew to the surface of the sample or applying a non-reflection coating film on the end face thereof. CONSTITUTION:Two kinds of non-reflection processing are available. One is cutting an end face of an optical fiber 5 askew. Reflected light on the end face A of the optical fiber 5 is mirror reflected on the end face A to irradiate inner wall surfaces of all cylinders. The inner wall surfaces of the cylinders are coated black. Thus, the reflected light on the end face A of the optical fiber 5 is prevented from being incident into the sample again. The other is applying a non-reflection coating film on the end face of the optical fiber. The inner wall surface of a cylinder 2 is so arranged that an end face at the light receiving end A is cut parallel with the surface of the sample to eliminate reflection of light on the wall surface while a non-reflection coating AC is applied.

Abstract: PURPOSE:To correct an estimate position and an estimate azimuth to be on an adjacent road with a small azimuth difference by generating a virtual road among object roads when plural object roads exist to correct the estimated position and azimuth. CONSTITUTION:When two roads 331, 332 whose azimuth difference from an estimated azimuth 323 calculated by an estimate position estimate azimuth arithmetic means 131 and whose distance from an estimate position 313 are a prescribed value or below exist adjacently to each other, an object road calculation means 132 takes a reciprocal of an area 333 between the roads 331 and 332 as a correlation value and generates a virtual road 341 by which the area 333 surrounded by the roads 331 and 332 is divided equally. Then a position azimuth correction means 134 corrects the estimate position 313 and the estimate azimuth 323 to a position 342 and an azimuth 343 on the virtual road 341. Thus, when roads with a very small azimuth difference exist adjacently, an event of the position of a vehicle not identified is avoided.
