Background technique
Pressurized-water reactor nuclear power plant forms pressures cycle in containment in normal course of operation, by slow boost process and
Quickly release process composition, the period 10-30 days.Containment pressure changes to+60mbar or so from -40mbar, (average every
Its+3---+8mbar), -40mbar is then fallen abruptly to again, is so recycled repeatedly.The increase of pressure is primarily due to for controlling
Pneumatic control valve compressed air for instrument (SAR system) processed constantly piii reactor workshop, the movement of regulating valve will lead to gas and release
It is put in containment.It is 100mbar since containment operates normally limit value, when pressure is raised to 60mbar or so, operations staff is logical
Atmospheric monitoring system in ETY(containment is crossed to be monitored and controlled) system exhaust, decline pressure.
Under unit accidental conditions, the pressure difference inside and outside containment arrives periodic cycle between+60hPa in -40hPa
(by ETY containment atmospheric monitoring system be monitored and controlled), at this time influence containment internal pressure variation because being known as safety
In shell pneumatic equipment work exhaust and leakage exhaust (SAR gas), trapped gases (mainly from RAZ nitrogen distribution system) with
And penetration piece leakage in the presence of containment inside and outside differential pressure etc..
Currently, the device volume for the measurement of containment leak rate is huge, the easy-to-use difference of equipment monitoring software, once there is event
Barrier stops monitoring, without effective spare monitoring method.
