| ENS 50618 | 15 November 2014 08:14:00 | This notification is being made as required by 10CFR 50.72(b)(3)(iv)(A) due to control room operators opening the Farley Nuclear Plant Unit 2 reactor trip breakers via the main control board hand switch during reactor startup procedures. This is a valid actuation of the reactor protection system. The reactor was not critical at the time the reactor trip breakers were opened. While withdrawing control rods for reactor startup and low power physics testing with control bank C at approximately 50 steps, Digital Rod Position indication for one of the control rods (M12) changed to 90 steps. The control room operators stopped withdrawing rods and entered FNP-2-AOP-19 (Malfunction of the Rod Control System). The reactor trip breakers were opened at 0353 CST. All rods inserted as expected. All other systems functioned normally. The plant is stable at normal operating pressure and temperature. The NRC Resident Inspector has been notified. |
| ENS 50604 | 12 November 2014 10:44:00 | At 0202 (CST) on November 12, 2014, it was determined that Unit 2 had no functional smoke detection capability in the containment. During post modification testing on the smoke detection system, it was discovered that both trains of detection were not functional. Required compensatory measures have been established. Since a fire in the containment is an entry condition for the site's Emergency Plan, this is considered an unplanned loss of emergency assessment capability and is being reported per 10 CFR 50.72(b)(3)(xiii). (Farley) Condition Report: 892818. The NRC Resident Inspector has been informed. |

The fire suppression system actuated as designed and the site fire brigade responded . There were no injuries or equipment damage. The fire is out and the licensee is monitoring the area. The licensee reduced power per their plant response procedures. The plant is stable and remains in Mode 1. The licensee has notified the State and local authorities and the NRC Resident Inspector.
The licensee exited the Unusual Event at 2036 CST, based on the fact that no equipment was damaged. The fire was believed to be from some hot work in the area igniting combustible material.
