Vendor File Error and Reactivity Managment SL
by Gibson, Kara A. 01 Mar '13

01 Mar '13

Prairie Island was just made aware that we received a file from the vendor for our flux map processing code that could impact our margin to the Fq TS limit. This error applies to the current operating cycle on one unit and a past cycle on the other unit. An assessment was done and the current operating cycle has enough margin to the TS Fq limit given the error. A past assessment needs to be performed for all the flux maps in the current operating cycle and all the flux maps in the past cycle. Two questions: If it is found that there is no impact on the Fq margin for past flux maps in the current operating cycle given the error should this still be classified as a level 3.10? The incorrect file was used, but without any violation of TS limits. For the previous cycle, would this event still be a level 3.10 if no TS limits were exceeded given the error? The Technical basis document, although not official, does state that the "SL of an issue is based on time of discovery and the impact of the technical error if it is implemented." Your input would be appreciated.

Reactor Engineering OJT/TPE
by Kelliher, Andrew P 28 Feb '13

28 Feb '13

As part of implementing ACAD 98-004 Revision 2 our fleet training department has been evaluating Reactor Engineering tasks for use of OJT/TPE instead of mentoring to obtain qualifications. I have the following benchmarking questions: · Has any station formally required OJT/TPE to obtain Reactor Engineering qualifications? o If so, which tasks require OJT/TPE? § What was your reasoning for requiring OJT/TPE? · For stations with moveable incore systems, operated by Reactor Engineers, have you evaluated requiring OJT/TPE to become qualified? o If so, what was your reasoning for either requiring or not requiring OJT/TPE? · For stations that have Reactor Engineers who modify plant process computer constants, have you evaluated requiring OJT/TPE to become qualified? o If so, what was your reasoning for either requiring or not requiring OJT/TPE? Any responses would be helpful. Thanks, Andy Andrew Kelliher Reactor Engineer R.E.
