Title: Method for estimating concentration of boric acid in moderator
IPC: G21C17/02
Filed: 1992-03-19
Abstract: PURPOSE:To provide a method of estimating the concentration of a boric acid in a moderator which makes it possible to know the concentration of the boric acid in the moderator of a reactor inexpensively, accurately and quickly. CONSTITUTION:A poison dissolving tank 35 injects poison into heavy water, a moderator of a reactor 31, and a poison removing tower 36 adsorbs the poison in the heavy water by strongly-basic anion exchange resin, while a heavy water clean-up tower 37 adsorbs impurities in the heavy water by weakly-basic anion exchange resin. A nuclear fission reaction is controlled by the concentration of the poison in the heavy water and the position of a control rod. While the amount of decrease of the poison concentration accompanying burnup of the poison due to neutron absorption in a core, the amount of increase of the poison concentration due to the injection from the poison dissolving tank 35 and the amount of decrease of the poison concentration accompanying the adsorption in the poison removing tower 36 are determined, the amount of the component of the strongly-basic anion exchange resin contributing to the adsorption of the poison in the weakly-basic anion exchange resin in the heavy water clean-up tower 37 is determined and the amount of decrease of the poison concentration accompanying the adsorption thereby is determined. In consideration of the amounts of these changes, the concentration of the poison in the reactor is determined.

Title: Diagnosing device for fault of exhaust valve of diesel engine
Inventor: FUKUYOSHI TADASHI
IPC: G01M15/04
Filed: 1987-03-23
Abstract: PURPOSE:To obtain a high-accuracy fault diagnostic device by providing a sampling valve, a controller, a CO analyzer, a comparator, an output device, etc. CONSTITUTION:When a controller 19 is set to a signal of 1st operation, a sampling valve 16 is opened for the valve opening period of an exhaust valve to sample and send exhaust gas to the CO analyzer 17, which analyzer CO. Its value is sent as A to a computer (COM) 22. Then when the controller 19 is set to a signal of 2nd operation, the valve 16 is opened while the exhaust valve is closed to sample and send the exhaust gas in a branch pipe 14a to the analyzer 17, which analyzes CO. Its value is sent as B to the COM 22. The COM 22 compares the analyzed values A and B with each other and outputs the result to an output device 25. Then when the exhaust valve is normal, there is no leak from the exhaust value during a combustion period, so none of the gas in a combustion chamber flows out to the branch pipe 14a and the values B and A are equal. If the exhaust valve is abnormal and its airtightness is spoiled, on the other other hand, the gas in the combustion chamber leaks out to the branch pipe 14a during the combustion period and the value B becomes larger than the value A, so the abnormality is decided.
