Title: Anticorrosion method for structural member of core in boiling water nuclear reactor
Inventor: YAMAZAKI KENJI
IPC: G21D3/08
Filed: 1993-02-26
Abstract: PURPOSE:To restrain stress corrosion crack of the structural member (stainless steel) of core while reducing the quantity of hydrogen to be used by injecting hydrogen into the core part through a CRD drive mechanism thereby lowering the corrosion potential at the core channel bypass part. CONSTITUTION:In the downstream of a CRD driven water pump (for feeding CRD driving water into a CRD drive mechanism 10) in a boiling water nuclear reactor, hydrogen fed from a hydrogen generator 29 is pressurized upto the pressure level in the core by means of a hydrogen pressurizing pump 30 and injected directly into core channel bypass part using the mechanism 10. Consequently, hydrogen concentration becomes about 0.3ppm at the inlet of the core channel bypass part and the corrosion potential lowers. At the upper and lower parts of the core channel bypass part, hydrogen concentration of water supply is 0.4ppm and the corrosion potential drops below-0.23V. In other words, corrosion potential of recirculation system can be lowered below -0.23V when the hydrogen concentration of supply water is set at 0.4ppm. Since the hydrogen concentration of supply water is 0.4ppm before the close rate in a I main steam piping 9 increases stress corrosion crack can be b restrained for all atainless steel in the nuclear reactor.

Abstract: PURPOSE:To obtain the quotient and residue as a result of operation with high accuracy, by controlling the number of times of repetition so that the quotient of a division of a numerical value expressed by a floating point format is obtained as an integer value, and constituting so that the quotient of an integer and the residue in that case are obtained. CONSTITUTION:A register 7 holds a sifference between a value of an exponential part register 1 of a dividend and a value of an exponential part register 3 of a divisor, and decides the number of times of repetition of a division. The division is executed by 3 processings consisting of pre-processing, repeated processing and post-processing. In the pre-processing, an initial condition for the division which does not execute add-return is set. Subsequently, in the repeated processing, the division which does not execute add-return is executed, and the operation is executed to 0.5 or -0.5 as the quotient. Subsequently, in the post- processing, the operation for correcting the value whose last quotient of repetition is 0.5 or -0.5, to an integer is executed. In this way, the quotient of a division of a numerical value expressed by a floating point format is obtained as an integer value, by which the quotient of an integer and the residue in that case can be obtained exactly.

IPC: G01N1/28
Filed: 1993-02-26
Abstract: PURPOSE:To reduce the cost of a test and to reduce the time of the test by reducing the number of tests which are made to obtain the basic physical property of a three-dimensional material required to design a three-dimensional composite material structure. CONSTITUTION:A test piece 1 is formed in such a way that a fiber 4 which is arranged and installed in one direction uses a carbon fiber and that a fiber 3 which is arranged and installed in the other direction and which crosses the carbon fiber used a fiber whose coefficient of elasticity is the same as that of a resin 2 forming a matrix. Thereby, since a composition rule and a lamination theory can be applied, the accurate elastic constant of a three-dimensional composite material can be obtained by the small number of test pieces. When the content of the carbon fiber is changed, the elastic constant can be obtained by a computing operation without a need for preparing a new test piece.

Filed: 1983-03-10
Abstract: PURPOSE:To increase fluorine ion conductivity, improve decrease of ion conductivity and thermal instability in air atmosphere to provide high ion conductivity by containing lithium fluoride in lead fluoride. CONSTITUTION:Lithium fluoride is contained in lead fluoride. For example, 0.1-50mol%, preferably 1-30mol% LiF powder having a purity of 99.9% or more is mixed to PbF powder having a purity of 99.9% or more to obtain a raw material powder. When LiF powder less than 0.1mol% is used, mixing effect of LiF is decreased and LiF exceeding 50mol% decrease ion conductivity. The sintering method requires the raw material powder having a particle size of 50-500 mesh. When a particle size is larger than 50 mesh, sintering effect is insufficient, and mixing effect of LiF is decreased. When a particle size is smaller than 500 mesh, uniform mixing is difficult and mixing of LiF is adversely affected.
