The following violation of very low significance (Green) was identified by the licensee and is a violation of NRC requirements that meets the criteria of Section VI of the
NRC Enforcement Policy,
NUREG-1600, for being dispositioned as an
NCV.
TS 3.3.2 requires that the
ESFAS instrumentation for each function in Table 3.3.2-1 shall be
operable. Table 3.3.2-1 function 1b, required two trains of
SI automatic actuation logic and actuation relays be
operable in Modes 3 and 4. Table 3.3.2-1 Function 5a, required two trains of
turbine trip and
feedwater isolation automatic actuation logic and actuation relays be
operable in Mode 3. Contrary to this, on March 20 and 21, 2008, two trains of
SI automatic actuation logic were not
operable, in that, both trains were blocked. Also on March 21, two trains of
SI and
feedwater isolation automatic actuation logic were not
operable, in that, both trains were blocked. This finding is more than minor because it affected the
Mitigating Systems Cornerstone objective and adversely affected the cornerstones equipment performance attribute for availability and reliability. A phase 2
SDP evaluation determined that the finding was of very low safety significance
