摘要： A power plant water chemistry analysis apparatus and method relies upon water chemistry sensors to obtain power plant water chemistry data characterizing the chemical activity of a power plant water system. An analytical model processor is used to generate model predictions for the power plant water system. A statistical data fitting processor selects screened data from the power plant water chemistry data that corresponds to the model predictions. The screened data is processed by an artificial intelligence processor to derive power plant water chemistry diagnostic information. The artificial intelligence processor includes an expert system, rule base, plant water chemistry system simulator, and pattern recognition module.

摘要： A method for mitigating general corrosion and crack initiation and growth on the surface of a metal components in a water-cooled nuclear reactor. A compound containing a non-noble metal such as zirconium or titanium is injected into the water of the reactor in the form of a solution or suspension. This compound decomposes under reactor thermal conditions to release ions or atoms of the non-noble metal which incorporate in the surfaces of the components, including the interior surfaces of any cracks formed therein. The preferred compounds are zirconium compounds such as zirconium acetylacetonate, zirconium nitrate and zirconyl nitrate. Zirconium incorporated in the oxided surface of a metal component will reduce the electrochemical corrosion potential at the surface to a level below the critical potential to protect against intergranular stress corrosion cracking without the addition of hydrogen.

摘要： A method for mitigating initiation or propagation of a crack in a surface of a metal component in a boiling water reactor. The method includes the step of injecting a solution or suspension of a pH-adjusting compound into the bulk water of the reactor. The compound has the property of changing the pH of high-temperature water inside the crack from a value outside a predetermined pH range (namely, pH 6.0 to 8.0) to a value within the predetermined pH range without causing any significant change of the bulk water pH. The growth rate of the crack when the crack pH is outside the predetermined pH range is greater than the growth rate of the crack when the crack pH is within the predetermined pH range.

摘要： Provision of an abnormality detection and suppression system for a valve apparatus, which is capable of detecting abnormal states such as leakage through valve seats or a gland/packing assembly and coping with the abnormality while ensuring protection for the valve apparatus by controlling a driving unit for a valve stem on the basis of information as detected, by means of a vibration sensor, a temperature sensor and a strain sensor are disposed internally of a valve stem 4 at a portion thereof which lies outside of a valve casing of the valve apparatus. When vibration of the valve stem brought abut by leakage through valve seats is detected by the vibration sensor in a fully closed state of the valve apparatus, a valve body thereof is driven further in the valve closing direction by a driving unit 13 controlled by a control unit, both being disposed externally of the valve casing, until the leakage and thus the vibrations disappear while monitoring simultaneously a load applied to the stem by the strain sensor. On the other hand, when a temperature change of the stem is detected by the temperature sensor in the fully open state of the valve apparatus, the control unit decides that the temperature change is due to leakage through a gland/packing assembly 12 of the valve apparatus to thereby control the driving unit so that the stem is driven to move the valve body in the valve opening direction while monitoring simultaneously a load applied to the stem until the change in the temperature is canceled out.

摘要： A method for improving the performance and longevity of coatings of metal deposited from aqueous solutions of inorganic, organic or oraganometallic metal compounds. The method involves co-deposition of noble metal or corrosion-inhibiting non-noble metal during growth of oxide film on a component made of alloy, e.g., stainless steels and nickel-based alloys. The result is a metal-doped oxide film having a relatively longer life in the reactor operating environment. In particular, incorporation of palladium into the film provides greatly increased catalytic life as compared to palladium coatings which lie on the oxide surface.

摘要： A gamma-rays measurement method of radionucludes (iodine-131, cobalt-60, etc.) coexisting with radionuclides (nitrogen-13, fluorine-18, cobalt-58, etc.) each emitting a pair of annihilation gamma-rays, particularly in primary water of a nuclear reactor by the use of a gamma-ray spectrometric system which includes a primary detector for detecting the gamma-rays and the one annihilation gamma-rays as pulses, a secondary detector for detecting the other annihilation gamma-rays as pulses, and shield detector for detecting gamma-rays Compton-scattered and escaped from the primary to shield detectors as pulses. The method comprises counting the pulses of the secondary detector in anticoincidence with the pulses of the primary detector, thereby to reject the recording of the annihilation gamma-rays from the primary detector, thus minimizing the annihilation gamma-rays disturbing to the measurement, followed by determining count numbers of the gamma-rays. Detection limits of the gamma-rays can be elevated significantly thereby. Simultaneously, further anticoincidence counting of the shield detector with the primary detector can be conducted to diminish the Compton-scattered gamma-rays.
