摘要： PROBLEM TO BE SOLVED: To provide simultaneous estimation of the distributions of temperature and heat flux, on both the interior and the exterior surfaces of the reactor vessel. SOLUTION: The distributions of temperature or heat flux on both the interior and exterior surfaces of the reactor vessel are calculated through an analysis of inversion problems with the equations of interpolation and extrapolation satisfied the equation of non-steady state heat conduction, based on the temperature information measured at the measuring points of in-wall temperature information of the reactor vessel. In other words, the solution of the equation of non-steady state heat conduction is expressed by the use of specified interpolation and extrapolation equations and parameters containing time and position vectors, and using the temperature information measured at the measured points of the temperature information the parameter values in the solution of the equation of non-steady state heat conduction are determined. Thus, when the discrete measured data of temperature is available in space and time, the temperature is estimated for the entire wall region of the reactor vessel (at arbitrary space-time points) governed by the equation for non-steady state heat conduction.

摘要： PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin metal composite which ensures the anticipation of long-term corrosionproofness, and a corrosionproof steel structure which is covered with this composite and shows outstanding on-site applicability.
SOLUTION: The fiber-reinforced resin metal composite is structured of a highly corrosion-resistant metal sheet covering the surface and the exposed end surface of a fiber-reinforced resin (FRP) and the corrosionproof steel structure is composed of the highly corrosion-resistant metal and a steel stock which are covered with the fiber-reinforced resin metal composite in an electrically insulated state. Thus the deterioration of the FRP due to light, water or the like is prevented from occurring by covering the surface and the exposed end surface of the FRP with the highly corrosion-resistant metal sheet. In addition, since it is possible to secure electrical insulation quality between the highly corrosion-resistant metal sheet and the steel stock to be covered and completely shut off the permeation of a corrosion factor from the surface by covering the steel structure with the composite structure, extremely excellent long-term corrosionproofness can be obtained for an on-site application method.
