4Q/08: LER 2008-003 was submitted in December. The LER included report of a SSFF, specifically a Nuclear Measurement Analysis and Control (NUMAC) drawer failure in the HPCI steam leak detection system. A correction has been entered for October 2008 to reflect a SSFF reported by LER 2008-002 submitted on October 17, 2008.
