| Title | Improper Preventive Maintenance Deletion Results in the Inoperability of the A Control Room HVAC System |
| Description | Green . A self -revealing Green non- cited violation ( NCV ) of Technical Specification ( TS ) 6.8.1, Procedures and Programs, as described in Regulatory Guide (R G) 1.33, Revision 2, February 1978, was identified when PSEG did not maintain an appropriate preventive maintenance ( PM ) schedule for the A control room heating, ventilation and air conditioning (HVAC ) system. Specifically, PSEG inadvertently deactivated a PM activity to perform periodic cleaning of the A control room return air fan (AVH -415) low flow switch pitot tubes that resulted in the A train of the control room emergency filtration ( CREF ) to be 3 unavailable on November 23, 2016 . PSEG performed corrective actions to clean the clogged pitot tubes associated with the AH -415 flow switch, re -activate the inadvertently deleted PM, and identify the extent of condition in other systems . This issue was more than minor because it was associated with the structures, systems and components ( SSC ) and barrier performance attribute of the Barrier Integrity Cornerstone (under the areas to measure associated with the radiological barrier function of the control room); and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors determined that the finding was of very low safety significance (Green) in accordance with IMC 0609, Attachment 4 and Appendix A, Exhibit 3, because the finding only represented a degradation of the radiological barrier function for the control room. The inspectors determined that there was no cross -cutting aspect associated with this finding since it was not representative of current PSEG performance. Specifically, the causal factors associated with this finding occurred in 2010, which was outside the nominal three- year period of consideration and were not considered representative of present performance in accordance with IMC 0612 |
