| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1.a requires, in part, that Written procedures shall be established, implemented, and maintained covering the applicable procedure
recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Appendix A, Section 7.d(4) includes sampling under procedures for BWR Air Extraction, Offgas Treatment, and Other Gaseous Effluent Systems. Contrary to the above, on June 17, 2014, the licensee failed to appropriately implement and maintain a gaseous effluent sampling procedure following the issuance and use of Plant Chemistry Procedure (PCP) 8.2, Kaman Effluent Monitoring System Operating Procedures, Revision 40. Specifically, due to the emergent failure of the turbine building exhaust stack normal range gaseous effluent monitor (Kaman 1) sample pump, PCP 8.2 was revised to allow for a temporary sample pump to be installed to maintain the turbine building exhaust stack high/extended range gaseous effluent monitor (Kaman 2) in a functional status. Section 11.5.9.1 of the UFSAR states, in part, that the extended rang airborne radiation monitor system was installed to satisfy the requirements of NUREG-0737, Item II.F.1, Attachments 1 and 2. Per NUREG-0737, Clarification of TMI Action Plan Requirements, Item II.F.1, Attachment 1, Table II.F.1-1, high range noble gas effluent monitor power supply consists of vital instrument bus or dependable backup power supply to normal AC. Following the revision to PCP 8.2, the temporary sample pump was powered from a welding receptacle which was not powered by a vital instrument bus or dependable backup power supply to AC. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Table 3 Appendix Router and IMC 0609 Appendix D, Public Radiation Safety Significance Determination Process. Because the finding involved the radioactive effluent release program but was not a substantial failure to implement the program and did not result i public dose greater than 10 CFR Part 20, Appendix I, or 10 CFR Part 20.1301(e) criterion, this finding screened as very low safety significance (Green). The above issue was documented in the licensees CAP as CR 01983162, Kaman 1 does not meet UFSAR/NUREG-0737 requirements. The licensee took immediate corrective actions to declare the affected effluent monitor nonfunctional, quarantined PCP 8.2, and ultimately removed the procedure steps that allowed the sample pump to substitute for the skid mounted pump. Additionally, the licensee made repairs to the effluent monitor system and returned the monitor to a functional status. |
