Event Notification Report for March 15, 2019

AUTOMATIC REACTOR TRIP DUE TO TURBINE GENERATOR TRIP

"On March 15, 2019 at 1300 EDT, Indian Point Unit 2 automatically tripped offline from mode 1 - 100% power operations. Reactor Operators verified the reactor trip and the plant is currently stable in mode 3. All automatic systems functioned as required. The auxiliary feedwater system actuated following the trip, as expected. All control rods fully inserted upon the trip, as expected.

"This event is reportable under 10 CFR 50.72(b)(3)(iv)(A) and 10 CFR 50.72(b)(2)(iv)(B). The unit remains on offsite power in hot standby at normal operating temperature and pressure. Decay heat is being removed from the steam generators via the auxiliary feedwater system and the condensate steam dump valves.

"Unit 3 remains in mode 6 for a scheduled refueling outage.

"The licensee notified the NRC Resident Inspector, the local transmission company, and New York State Independent System Operator."

The Indian Point Unit 2 automatic trip was caused by the trip of the main generator. The cause of the generator trip is unknown at this time.

AGREEMENT STATE - THREATENED OVER-EXPOSURE

The following was received via e-mail:

"On March 14, 2019 around 1430 CDT, Turner Industries Group, LLC was performing work in a permanent shooting cell. Two industrial radiographers got into a verbal altercation, which lead to one industrial radiographer cranking out a source onto the other industrial radiographer. Dose reconstruction indicated less than 2 millirem/hr whole body to the one radiographer. The first radiographer was twelve feet from the four Half-Value Layer (HVL) collimator and ran to a shielded condition within seconds after realizing the source had been cranked out. The second radiographer was behind a shooting cell wall performing the crankout.

"The radiographer performing the crankout has been terminated and led off the property. All access that he had has been revoked and access codes changed."

UNUSUAL EVENT DECLARED DUE TO HIGH RIVER LEVEL

At 0546 CDT, Cooper Nuclear Station declared an Unusual Event due to the Missouri River level reaching 899.05 feet above mean sea level (MSL), which is above the Emergency Action Level (EAL) HU 1.5 elevation of 899 feet above MSL. The river is expected to crest above 901 feet above MSL within the next day, and remain above 899 feet above MSL for the next several days.

Declaration of an Unusual Event is a 1 hour report, and is reportable under 10 CFR 50.72.a.1.1. Actions are in progress in accordance with site flooding procedure, including strategic placement of barriers at building entrances and important facilities. There is no major plant equipment out of service at this time. Personnel access to the site is not presently impeded and emergency evacuation routes remain available.

A press release is planned for this event, which is a four hour report, reportable under 10 CFR 50.72.b.2.11.

If the Missouri River were to reach 901.5 feet above MSL, Cooper would initiate a unit shutdown in accordance with their procedures. If the Missouri River were to rise greater than 902 feet above MSL, Cooper will declare an Alert.

The licensee notified the NRC Resident Inspector.

Notified DHS SWO, FEMA Operations Center, DHS NICC, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).

* * * UPDATE AT 1742 EDT ON 3/24/2019 FROM KLINTON BEHRENDS AND CURTIS MARTIN TO JEFFREY WHITED * * *

The licensee terminated the Unusual Event at 1601 CDT due to lowering Missouri River water levels. River water level is currently at 896.0 feet MSL and lowering.

"A press release will be issued to inform the public of Cooper Nuclear Station's exit from the Notification of Unusual Event regarding high Missouri River level. The initial entry into the Notification of Unusual Event occurred on 03/15/2019 and was exited on 03/24/2019 at 1601 CDT. The press release is reportable per 10 CFR 50.72(b)(2)(xi)."

AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGES

The following was received via fax:

"The Radiation Safety Officer [RSO] for Parsons called to report that four (4) generally licensed fixed slurry moisture gauges were missing. Each gauge contained 90 microCuries of cesium-137. All devices were of Ronan Engineering RLL-1 1619 5L2A3 make and model, and sources were of Ronan SRC-PT-CS-90UCL make/model. The device serial nos. are: DX-520 with source s/n DE-520; DX-814 with source s/n DE-814; DX-816 with source s/n DE-816; and DX-818 with source s/n DE-818. These sources were inadvertently left at 522 Gerelock Road, Camillus, New York 13031 following completion of extensive contract work for Honeywell International. The sources were identified as lost by the RSO on March 15, 2019, at 1600 EDT. These sources were not found upon the RSO's return to the Camillus facility, and the RSO reported the lost sources to NYSDOH [New York State Department of Health] on March 18, 2019, at 0830 EDT. Parsons will be contacting Honeywell International and other contractors at this facility to locate the missing sources. NYSDOH Incident number 1272 assigned to track this event."

New York Event Report ID No.: NY-19-01

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
