Abstract

The U. S. Nuclear Regulatory Commission (NRC) conducts a radioactive waste system inspection program with nuclear power facility licensees. The confirmatory measurements portion of the program consists of a test of the licensee's measurements of radioactivity in actual or simulated plant effluent samples (liquid, off-gas, participate filter, and charcoal adsorber), comparing the licensee's measurements with those of the NRC reference laboratory.

The NRC has developed a computer data analysis system (CDAS) which performs comparisons of the analytical results of the licensee and NRC reference laboratory and which provides statistical analyses of licensee performance. Licensee ability to adequately identify and quantify radionuclides in plant effluents is thereby documented. Comparison of these analytical results is the basis for the NRC Confirmatory Measurement Inspection Program.
