SAFETY PARAMETERS DISPLAY SYSTEM OUT OF SERVICE
"At 1032 [EDT], on June 12, 2012, the Unit 2 Safety Parameter Display System (SPDS) system ceased valid data transmission to the control room computer terminals. Remote terminals were unaffected. The loss was discovered on the morning of 6/13/12 and the connection was restored at 0945 [EDT] on 6/13/12. This was a duration of greater than 8 hours which was not discovered until after the fact. This condition affected unit 2 only. ERDS was unaffected.
"Since the Unit 2 SPDS computer system was unavailable for greater than 8 hours, this is considered a Loss of Emergency Assessment Capability and reportable under 10CFR50.72(b)(3)(xiii)."
The licensee notified the NRC Resident Inspector.

UNUSUAL EVENT AFTER AN AMMONIUM HYDROXIDE SPILL IN THE ADMIN BUILDING
"Seabrook declared an Unusual Event [HU3 - hazard or other conditions affecting plant safety] due to a spill of one gallon of ammonium hydroxide in the stockroom area of the Administration Building. No reports of injured individuals [were received] at this time. No plant or equipment damage occurred. The lower level of the Administration Building is evacuated. Personnel in SCBAs [Self Contained Breathing Apparatus] are mitigating the spill."
The Administration Building is in the Protected Area adjacent to the Turbine Building.
The licensee notified the NRC Resident Inspector and the State.
Notified DHS, FEMA, NICC, DOE, USDA, and HHS.
* * * UPDATE AT 1747 ON 6/13/2012 FROM ED LYONS TO MARK ABRAMOVITZ * * *
"At 1343 [EDT] on 6/13/12 an Unusual Event was declared due to a reported Ammonium Hydroxide spill in a storeroom on the first floor of the Administration Building. At 1357 [EDT] the State of NH was notified and at 1401 the State of Massachusetts was notified of the Unusual Event using the State Notification Fact Sheet. The delay to the State of Massachusetts notification was due to issues with the dedicated phone system.
"At 1422 the NRC was notified of the Unusual Event using the Event Notification Worksheet. This initial notification reported a one gallon spill of Ammonium Hydroxide. Additionally there were no reported injuries and no impact to plant equipment.
"Further investigation revealed that the spill amount is 1-2 pints out of a 1 gallon container and the initial report of no injuries was validated. The concentration of the Ammonium Hydroxide is 25.5%. The spill was confined to a small area of the store room on the first floor of the Administration Building. The spill had no impact on plant equipment used for normal operation. Initial cleanup by plant personnel is complete and external services have been notified to complete the final spill cleanup.
"Seabrook Station is terminating the Unusual Event. Seabrook Station will continue to investigate and resolve the issues with the dedicated state notification phone system. Currently we have a troubleshooting team which has verified backup communications via the commercial phone lines is available."
The Unusual Event was terminated at 1730 EDT.
The licensee notified the NRC Resident Inspector and State.
Notified R1DO (Gray), NRR ((Howe), IRD (Grant), DHS, FEMA, NICC, DOE, USDA, and HHS.

HIGH PRESSURE COOLANT INJECTION SYSTEM DECLARED INOPERABLE
"On 6/13/12 at 1700 CDT, it was determined that valve 2-FCV-73-81 (HPCI steam line warm-up valve) was not capable of performing its intended primary containment isolation valve function. This determination was made during performance of a prompt determination of operability for a steam leak from a missing adapter on a Furmanite injection port in the valve packing area. To meet Technical Specification (TS) 3.6.1.3 action requirements for an inoperable primary containment isolation valve, 2-FCV-73-2 (HPCI inboard steam isolation valve) was closed at 1745 hrs., rendering U2 HPCI inoperable. As a result TS 3.5.1 actions were entered.
"This incident is reportable as an 8-hour ENS notification under 10CFR 50.72 (b)(3)(v)(B) and (D) as 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to remove residual heat and mitigate the consequences of an accident.'
"It also requires a 60 day written report in accordance with 10CFR 50.73(a)(2)(v)(B) and (D).
"The NRC Resident Inspector has been notified.
"This event has been entered into the Licensee's Corrective Action Program as SR 565729."
Technical Specification 3.6.1.3 had a 4-hour shutdown action statement which was satisfied when the HPCI inboard steam isolation valve was closed. Technical Specification 3.5.1 action statement is a 14-day shutdown LCO.
