Bently Nevada 146031-02 Key Features
Nuclear-grade seismic certification: The 146031-02 passed IEEE 344 testing simulating a main steam line rupture (MSLB) condition, achieving signal distortion of <1% under 5g random vibration.
Radiation-resistant: The bismuth germanium oxide (BGO) crystal sensor element enables the 146031-02 to maintain accuracy drift of <±3% under a 10⁶ Gy radiation dose.
LOCA (Loss of Coolant Accident) survival: The integral Inconel X750 seal structure meets the requirements for continuous operation in a 10 MPa/170°C loss-of-coolant accident (LOCA) environment.
Application examples of foreign nuclear power plants
The Flamanville 3 EPR reactor in France is equipped with 78 146031-02 sensors to monitor the vibration of the main pump bearings. Through LOCA environmental simulation testing, the commissioning cycle was shortened by 14 months.
The Vogtle Nuclear Power Plant in the United States is installing a 146031-02 array within the containment of the AP1000 unit to monitor the vibration status of the residual heat removal pump in real time, with the data directly fed into the NRC regulatory system.
