At 1800, May 9, 2013, the Columbia Generating Station main control room received notification that PWC-XR-1 had been found to be not recording data. A review of the stored data indicated that the data collection had been stopped since 5/2/2013 at 0934. The screen does show real time data, although that data is not being stored. Some of the data is recorded manually by chemistry technicians and operators during rounds that may be used for reporting purposes.
Automatic functions for high turbidity shutdown and low chlorine setpoints remain active when the data is not being stored. The data collected by PWC-XR-1 includes inlet and outlet flocculator turbidity, water temperature, flow rate and free residual chlorine. Washington Administrative Code, WAC, 246-290-664 outlines the requirements for monitoring filtered systems. WAC 246-290-480 section 2.a requires this failure to be reported as a failure to comply with monitoring requirements to the Washington Department of Health within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
PWC-XR-1 data storage has been re-initiated and is working as expected.
The licensee notified the NRC Resident Inspector.
