The letter states that: "If the criteria for the completion of the test program is understood to be the first successful test in accord:1ce with Vogtle Electric Generating Plant (VEGP) procedure 14990-1 " Diesel Generator Operability Test," then there were 10 successful starts of Diesel Generator IA and 12 successful starts of Diesel Generator 18 between the completion of the test program and the end of April 19, 1990, the date the LER-424/1990-06 was submitted to the NRC. The number of successful starts included in the original LER (at least 18) included some of the starts that were part of the test program. The difference is attributed to diesel start record keeping practices and the definition of the end of the test program."
