| Title | Failure to Address Noticeable Differences in the Simulator in Accordance with Ansi/Ans 3.5-1998 and -2009 |
| Description | The inspectors identified a finding associated with addressing noticeable differences between the simulator and the plant in accordance with the standards of ANSI/ANS 3.5-1998 and -2009. Specifically, there was a failure to correct a difference in the operation of recirculation pumps identified in 2006 while conducting transient testing prescribed by the ANSI standard. In addition, there was a failure to install a simulator modification to reflect an actual reference plant modification relevant to operator training within 24 months. The licensee initiated corrective action documented in Action Request 277631. Failure to correct noticeable differences between the simulator and the plant that were relevant to operator training in accordance with the ANSI/ANS 3.5 Standard (-1998 and -2009 revisions) was a performance deficiency. The performance deficiency is more than minor because it adversely impacted the human performance attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Additionally, if left uncorrected, the performance deficiency could have become more significant in that not correcting noticeable differences between the simulator and the plant can provide the potential for negative training to the licensed operators. Using Manual Chapter 0609, Significance Determination Process, Attachment 4, Tables 1 and 2 worksheets, and the corresponding Appendix I, Licensed Operator Requalification Significance Determination Process (SDP), Flowchart Block #14, the finding was determined to have very low safety significance (Green) because it dealt with deficiencies associated with simulator testing, modification, and maintenance and there was no actual plant event caused by the issue with maintaining the simulator. This finding has a cross-cutting aspect in the problem identification and resolution area associated with the corrective action program - taking appropriate corrective action |
