Technical Specification 5.5.2 (c), Radioactive Effluent Controls Program, requires monitoring, sampling, and analysis of gaseous effluents. Contrary to the above, from 1989 to the present, the sample pump flow rates through several isokinetic nozzles was too high to allow for accurate monitoring and representative sampling. In 1989, automatic flow control features of some effluent monitoring instruments were disabled and in 2016, several new monitors were installed on the same isokinetic nozzle sample lines. Both of these actions prevents accurate monitoring and representative sampling.Significance/Severity: The inspectors evaluated this finding using
IMC 0609.04, Initial Characterization of Findings, and
IMC 0609, Appendix D,
Public Radiation Safety Significance Determination Process. The inspectors determined that finding was of very low safety significance (Green).Corrective Action Reference(s): CR-2017-04211 and CR-2018-00283
