The research and application of advanced algorithm of detection of Npp's containment air

This article focuses on an advanced technique of detecting the aerosol radiation in the nuclear power plant containment air, and analyses the principle and algorithm of the technique, which is better than the other techniques. For the advanced technique, the Radon daughters are involved in the calculation algorithm, and then the Radon daughters can be compensated during the calculation process, which makes the calculated value more precise, and avoids the flash alarms caused by Radon daughters. This technique has already been used in some of the domestic nuclear power plants, and got very good user feedback, so this technique is a good choice for the new nuclear power plants. (author)
