| Description | TS 3.3.5.1, ECCS Instrumentation, states the ECCS instrumentation for each function in Table 3.3.5.1 1 shall be operable. As specified in Table 3.3.5.1 1, Function 3b, HPCI System High Drywell Pressure (4 channels) and Function 3f, HPCI System Manual Initiation (1 channel) are required to be operable in Modes 1, 2, and 3 with reactor steam dome pressure greater than 150 psig. TS 3.3.5.1, Required Action A.1 states with one or more channel(s) inoperable, immediately enter the condition referenced in Table 3.3.5.1 1 for the channel. Table 3.3. 5.1 1, Function 3b, references Condition B for inoperable HPCI System High Drywell Pressure channels. Required Action B.2 states declare the HPCI system inoperable within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> from discovery of loss of HPCI initiation capability and Required Action B.3 states place the affected channel(s) in trip within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Table 3.3.5.1 1, Function 3f, references Condition C for an inoperable HPCI System Manual Initiation channel. Required Action C.2 states restore the channel to operable status within 24 hours . If the required actions and associated completion 42 times of Condition B or C are not met, Required Action G.1 states immediately declare the associated supported feature (i.e., HPCI system) inoperable. TS 3.5.1, ECCS Operating, states, in part, each ECCS injection subsystem shall be operable in Modes 1, 2, and 3, except HPCI is not required to be operable with reactor steam dome pressure less than or equal to 150 psig. With the HPCI system inoperable, Required Action E.1 states immediately verify by administrative means RCIC system is operable and Required Action E.2 states restore HPCI system to operable status in 14 days. If the required actions and associated completion times of Condition E are not met, Required Action I.1 states be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. LCO 3.0.4.b is not applicable to HPCI. TS 3.3.5.2, RCIC System Instrumentation, states the RCIC instrumentation for each function in Table 3.3.5.2 1 shall be operable in Modes 1, 2, and 3 with reactor steam dome pressure greater than 150 psig. As specified in Table 3.3.5.2 1, Function 4, RCIC System Manual Initiation (one channel per valve) is required to be operable. TS 3.3.5.2, Condition A states with one or more channels inoperable, immediately enter the condit ion referenced in Table 3.3.5. 21 for the channel. Table 3.3.5.2 1, Function 4, references Condition C for an inoperable RCIC System Manual Initiation channel. Required Action C.1 states restore the channel to operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. If the required actions and associated c ompletion times of Condition C are not met, Required Action E.1 states immediately declare the RCIC system inoperable. TS 3.5.3, RCIC System, states the RCIC system shall be operable in Modes 1, 2, and 3 with reactor steam dome pressure greater than 150 psig. With the RCIC system inoperable, Required Action A.1 states immediately verify by administrative means HPCI system is operable and Required Action A.2 states restore RCIC system to operable status in 14 days. If the required actions and associated completion times of Condition A are not met, Required Action B.1 states be in Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. LCO 3.0.4.b is not applicable to RCIC. TS 3.0.4, Limiting Condition for Operation (LCO) Applicability, Paragraph (a) states, in part, when a LCO is not met , entry into an operational mode or other specified condition in the applicability shall only be made when the associated actions to be entered permit continued operation in the operational mode or other specified condition in the applicability for an unli mited period of time. This specification shall not prevent changes in modes or other specified conditions in the applicability that are part of a shutdown of the unit. Contrary to the above: 1. On six occasions (February 10, 2014, April 16, 2014, March 19, 2015, September 13, 2015, May 3, 2016, and November 7, 2016 ), the licensee entered Mode 3 following plant shutdowns without declaring the HPCI system instrumentation functions of high drywell pressur e and manual initiation inoperable and entering LCO 3.3.5.1. During the shutdowns, Fermi 2 was in Mode 3 for up to fifteen hours with reactor steam dome pressure greater than 43 150 psig without the licensee satisfying TS 3.3.5.1, Required Actions A.1, B.2, and G.1. This is a violation of TS 3.3.5.1. With HPCI inoperable as specified by TS 3.3.5.1, Required Actions B.2 and G.1, the licensee did not satisfy TS 3.5.1, Required Action E.1. This is a violation of TS 3.5.1. 2. On six occasions (February 10, 2014, A pril 16, 2014, March 19, 2015, September 13, 2015, May 3, 2016, and November 7, 2016 ), the licensee entered Mode 3 following plant shutdowns without declaring the RCIC system instrumentation function of manual initiation inoperable and entering LCO 3.3.5.2 . During the shutdowns, Fermi 2 was in Mode 3 for up to fifteen hours with reactor steam dome pressure greater than 150 psig without the licensee satisfying TS 3.3.5.2, Required Action A.1. This is a violation of TS 3.3.5.2. 3. On six occasions (March 28, 2014, April 21, 2014, April 3, 2015, November 25, 2015, May 12, 2016, and November 11, 2016 ), the licensee entered Mode 2 with reactor steam dome pressure greater than 150 psig during plant startups without declaring the HPCI system instrumentation functions of high drywell pressure and manual initiation inoperable and entering LCO 3.3.5.1. For up to nineteen hours during this time, the licensee did not satisfy TS 3.3.5.1, Required Actions A.1, B.2, and G.1. This is a violation of TS 3.3.5.1. With HPCI in operable as specified by TS 3.3.5.1, Required Actions B.2 and G.1, the licensee did not satisfy TS 3.5.1, Required Action E.1. This is a violation of TS 3.5.1. 4. On six occasions (March 28, 2014, April 21, 2014, April 3, 2015, November 25, 2015, May 12, 2016, and November 11, 2016 ), the licensee entered Mode 2 with reactor steam dome pressure greater than 150 psig during plant startups without declaring the RCIC system instrumentation function of manual initiation inoperable and entering LCO 3.3.5.2. For up to nineteen hours during this time, the licensee did not satisfy TS 3.3.5.2, Required Action A.1. This is a violation of TS 3.3.5.2. 5. On six occasions (March 28, 2014, April 21, 2014, April 3, 2015, November 25, 2015, May 12, 2016, and November 11, 2016 ), the licensee entered Mode 2 with reactor steam dome pressure greater than 150 psig during plant startups without meeting the LCOs of TS 3.3.5.1 and TS 3.3.5.2 for HPCI and RCIC systems instrumentation functions of high drywell pressure (HPCI only) and m anual initiation ( both HPCI and RCIC) . This is a violation of TS 3.0.4. This violation was entered into the licensees corrective action program as CARD 16 26153. The violation was determined to be of very low safety significance (Green) during a detailed Significance Determination Process review since the CDF was determined to be less than 1.0E -7/year. |
