| NPP PERSONNEL CONTAMINATION CONTROL SYSTEM RZS-02A | |
PURPOSE
Implementation of sanitary access mode at NPPs under construction and reconstruction for contamination control of:
- Protective clothing, shoes and other means of personal protection at the exit from limited access area to the working clothes change room of decontamination station;
- Personnel skin and head at the exit from shower cabins to the personal clothes change room of decontamination station.
FEATURES
- Combined detecting units of domestic manufacture based on plastic scintillators – 24 items;
- Separate recording and processing of beta and gamma radiation by each detecting unit;
- Automatic gamma background compensation;
- Visual and sound support of measurement procedure;
- Blocking of passage in case of personnel contamination;
- Automatic control of system configuration and detecting units performance;
- Possibility to control small objects;
- Accounting of personnel identification means during performance of measurement;
- External communications via RS485 or Ethernet;
- High mechanical strength of input/output blocking devices;
- External components made of stainless steel.
