Specifications
Specifications are listed in table 1.
546NS Qualification
The 546NS is qualified to meet stringent environmental conditions encountered in nuclear power plant containment
areas. Samples were subjected to the tests summarized below:
D Thermal Aging: accelerated service temperature of 54_C (130_F) over 10 years.
D Radiation Aging: 6 MRads Total Integrated Dose (TID)
D Seismic Event Simulation (DBE): no natural frequencies found between 5‐100 Hz and seismic dwells of 8g uniaxial
from 3‐40 Hz when mounted using Fisher specified seismic mounting brackets.
D LOCA/MSLB Event Simulation: saturated steam for 14 hours at 160_C ( 320_F) followed by a gradual reduction to
83_C (182_F) over a 10 hour period.
Upon conclusion of the above tests, no loss of function or visible degradation was found.
