Evaluating the impact of hypothesis testing on radioactivity measurement programs at a nuclear power facility

NUREG 4007, lower limit of detection: Definition and elaboration of a proposed position for radiological effluent and environmental measurements proposed the application of hypothesis testing to nuclear power plant radiological effluent technical specification (RETS). Although hypothesis testing has been implicit in the current RETS, the application of the NUREG proposal will require a more detailed knowledge of the measurement system uncertainties, establishment of a basis for assumed boundary conditions for these uncertainties and a heightened degree of control over measurement processes. This paper applies the requirements of the NUREG to three types of radiometric measurement systems routinely used for compliance with the RETS. The methods used to meet the requirements will be detailed
