| Title | Failure to Have Procedures to Prevent Draining Radioactive Systems into Nonradioactive Systems |
| Description | The inspectors reviewed a self-revealing noncited violation of Technical Specification 5.4.1.a for failure to implement written procedures to prevent draining and venting radioactive systems into nonradioactive systems and prevent unplanned releases of radioactivity into the environment. On October 21, 2009, an auxiliary building operator inadvertently connected a hose carrying radioactive water to a hose that was routed into the auxiliary building nonradioactive sump. Consequently, the operator drained an estimated 800 to 1,000 gallons of reactor coolant into the nonradioactive auxiliary building sump which transferred its radioactive contents to the turbine building sump. When the contaminated turbine building sump attempted to transfer liquid radioactive waste to the non-radioactive wastewater retention basin, radiation monitor RE95 alarmed and terminated the discharge due to the Hi-Hi radioactivity setting of 7.25E-5 uCi/ml. The licensee immediately implemented a decontamination recovery plan. This event was entered into the licensees corrective action program as Condition Reports 20995, 20999, and 29295. The inspectors determined that failure to have procedures to prevent draining and venting radioactive systems to nonradioactive systems was a performance deficiency. The finding was more than minor because it impacted the program and process attribute of the Public Radiation Safety Cornerstone, and it adversely affected the cornerstone objective of ensuring adequate protection of public health and safety from exposure to radioactive material released into the public domain. Using the Public Radiation Safety Significance Determination Process, the inspectors determined this finding to be of very low safety significance because this was not a failure to implement the effluent program, and it had no impact on public dose. In addition, this finding has a crosscutting aspect in the area of Human Performance related to the personnel work practices component. Specifically, the licensee failed to use self- and peerchecking human error prevention techniques and then proceeded in the face of uncertainty when unexpected plant conditions were known. |
