'Ihis suhaittal identified that the Wolf Creek Generating Station (NOGS) sinulator was functioning at a level approximately eight percent slower than "real time " as measured by performance testing.
It was also' stated that this deviation from "real t.ime" had not resulted in any impact on the licensed operator training. g,- e.
NCNOC is cammitted to maintaining the fidelity of the NOGS sinulator and will take necessary actions to correct significant deviations ftun "real time" sinulation which have been detaunined to adversely inpact licensed operator training gymie.
' Sino's the initial subnittal of the NCIES simulator certificatico, NCNOC has continued to pursue inproving.the "real tine" performance of the NCX3S sinulator.
