Description
При проведении р да исследовательских работ необходимо выполнить дистапционное измерение количества газов, выдел ющихс в тепловыдел ющих элементах (ТЕЭЛ) дерного реактора в нроцессе экснеримента. Количество выдел ющегос газа (адсорбированные газы и газообразные осколки делени ) можно оценить путем измерени давлени в ТВЭЛ. Известно устройство дл дистанционного измерени давлени в ТВЭЛ, состо щее из ТВЭЛ и датчика давлеин , расположенного пепосредственно на ТВЭЛ и реагирующего на изменение давлени в нем. Определить количество выдел ющихс газов с помощью этого устройства практически иевозможио, поскольку измер емое давление сильно зависит от температуры топлива, которую трудно контролировать. Целью изобретеин вл етс создание устройства , в котором было бы исключено вли пие температуры топлива на давление, создаваемое выдел юп1,имис газами. Дл этого в предложенное устройство введена имеюгца стабильную температуру балластна емкость, раеположеппа между ТВЭЛ и датчиком давлени , объем которой определ етс из соотиощени : ZP S ср.тв TQГд где VQ - объем балластной емкости, Гц - температура балластной емкости, Уд - объем датчика давлени , см Тт, - температура датчпка давлеии , FT,, - свободный объем ТВЭЛ, Тс. ТВ - среди температура ТВЭЛ, °К; 6 - вли ние, оказываемое ТВЭЛ на нз.мер емое давление, относительно вли ний, оказываемых балластной емкостью и датчиком давлени , %. Дл поддержани стабильной температуры балластной емкостн она должна xopoino омыватьс теплоносителем, температура которого практически посто нна. Ма чертеже показано нред.:юженное устройство , состо щее из ТВЭЛ 1, балластной емкости 2, температура которой стабилизирована , и датчика давлени 3. Измерив датчиком, например, компеисапионного тина дайлспие в устройстве, можно точно рассчитать количество газов, выделившихс в ТВЭЛ к данному . Де1,ствительно, величина давлеии в элементарном объеме пространства определ етс по соотношению:When conducting a series of research works, it is necessary to perform a distortion measurement of the amount of gases released in the heat generating elements (TEEL) of the nuclear reactor in the process of extraction. The amount of released gas (adsorbed gases and gaseous fission fragments) can be estimated by measuring the pressure in the fuel element. A device is known for remote pressure measurement in a fuel element consisting of a fuel element and a pressure sensor located directly on the fuel element and reacting to a pressure change in it. Determining the amount of evolved gases with this device is practically impossible since the measured pressure is strongly dependent on the temperature of the fuel, which is difficult to control. The aim of the invention is to create a device in which the influence of the fuel temperature on the pressure created by the release of the impelled gases is eliminated. To do this, the ballast tank has a stable temperature entered in the proposed device, between the fuel element and the pressure sensor, the volume of which is determined from the ratio: ZP S cf.vt.TQGd where VQ is the volume of the ballast capacity, Hz is the pressure sensor , cm Тt, - temperature of pressure sensor, FT ,, - free volume of fuel elements, Tc. TV - among the temperature of the fuel elements, ° K; 6 - the influence exerted by TVEL on the measured pressure, relative to the effects exerted by the ballast capacity and the pressure sensor,%. In order to maintain a stable temperature, the ballast capacitance must be washed by the xopoino coolant, whose temperature is almost constant. The drawing in the drawing is shown as: a southern device consisting of a fuel cell 1, a ballast tank 2, whose temperature is stabilized, and a pressure sensor 3. By measuring with a sensor, for example, a companion gas in the device, it is possible to accurately calculate the amount of gases released in a fuel cell . Indeed, the pressure value in an elementary volume of space is determined by the relation:
