The Westinghouse equipment lifetimeTM monitor

The Westinghouse Equipment LIFETIMETM Monitor addresses a long-standing need in the nuclear industry - a way to continuously and passively monitor the temperature and radiation environment of components located throughout the plant. This compact device (approximately 2.5 x 2.3 x 1.3 inches) is capable of performing up to six different functions. Each function is designed to measure a different type or range of environmental parameter. Monitoring options include peak temperature, integrated temperature, low and high range gamma ray dose, beta particle dose, and neutron radiation. These various functions allow flexibility in selecting the precise environmental parameters to be monitored to meet plant specific requirements and budget constraints. The data acquired from the Equipment LIFETIMETM Monitor can be used in a variety of ways, including: extending the qualified life of safety-related equipment by improving on initial assumptions regarding service environment; conducting long term temperature and radiation surveys to ensure operation within qualified limits; assessing potential age-related degradation of major high cost components for purposes of plant life extension, and justifying continued use of equipment following an accidental excursion in environmental radiation or temperature
