LAM-541
Liquid Activity Monitor
Measurement of the total volumetric activity of noble gases emitting gamma radiation in the ventilation line from the turbine condenser vacuum-pump sump under routine operating conditions.
Nuclear Facilities
Key Features
- Measurement of the volumetric activity of a steam-air mixture in the ventilation line of vacuum‑pump sumps at nuclear power plants.
- In-Line monitor type: the detector is mounted inside the measured pipeline.
- Built-in LED check source for automatic spectrum stabilization and functional testing.
- Optional safety‑classified function, Category C according to IEC 61226.
Description
The monitor is designed to measure the total volumetric activity of noble gases emitting gamma radiation in the ventilation line from the turbine condenser vacuum‑pump sump under routine operating conditions.
The LAM-541 monitor assembly consists of:
- NGD-41 detector assembly, comprising:
- a temperature‑resistant scintillation detector with a YAP crystal,
- electronics for pulse processing and evaluation at the measurement point,
- a LED-based check and stabilization source.
- RPU‑06 radiation processing unit.
