Waste Confidence Schedule Adjustment

Greetings,

Due to the government shutdown and subsequent rescheduling of public meetings and extension of the public comment period, the Commission has granted the Waste Confidence Directorate a four-week extension to the overall rulemaking schedule.  However, in granting the extension, the Commission urged the Waste Confidence Directorate to continue to work towards the original September 2014 deadline for the rulemaking, and the Directorate is doing just that.  A press release regarding this announcement was issued this afternoon:  http://www.nrc.gov/reading-rm/doc-collections/news/2014/14-003.pdf.   Any additional schedule-related announcements will continue to be made via WCOutreach e-mail and will be posted to our website at http://www.nrc.gov/waste/spent-fuel-storage/wcd/schedule.html.

And finally, a quick reminder that the Waste Confidence Directorate will be hosting a status update teleconference on Wednesday, January 29th, from 1:30 p.m. to 2:30 p.m. EST.  To participate, prior to the start of the meeting, please dial 1-800-475-8385 and provide the operator with passcode 80907.

Sincerely,
 
Staff of the Nuclear Regulatory Commission
Waste Confidence Directorate

Event Text


VENT STACK RADIATION MONITORS OUT OF SERVICE 

 

"At 1340 [EST] on 1/21/2014, Susquehanna Control Room Operators received an alarm due to the lockup of a monitoring panel utilized for Vent Stack Radiation Monitors (known as SPINGs - System Particulate, Iodine, and Noble Gas). There are two monitor panels, one in the control room and one in the Technical Support Center (TSC). Both panels are fully redundant. At the time, the control room panel was out of service for maintenance. 

 

"This event rendered all five SPINGs inoperable. Additionally, control room alarm capability was not available. The associated Technical Requirement (TROs) were entered for this inoperability. In order to clear the lockup, the TSC terminal needed to be powered down and rebooted. 

 

"The TSC monitoring terminal was restored to operable status at 1352 and the associated TROs were cleared. The SPING function and control room alarm functions were inoperable for a total of 12 minutes. 

 

"In accordance with the guidance of NUREG 1022, Revision 3, Item 3.2.13, this event is being reported as an 8 hour ENS notification due to a loss of emergency assessment capability. The loss of the Stack Monitoring System was not part of a pre-planned evolution. This equipment is relied upon by control room operators and emergency response personnel to implement procedures addressing classification, assessment, and protective actions associated with the emergency plan." 

 

The licensee notified the NRC Resident Inspector.

Update on Toronto GE-Hitachi Struggle

Nuclear failure
Latest chapter in nuke watchdog’s fight with west-end residents over GE uranium plant ends in a meltdown
By Saul Chernos

It was a meltdown that GE Hitachi and the Canadian Nuclear Safety Commission likely hoped to avoid.

But it happened nonetheless.

After two days of testy back and forth between residents and CNSC members at a meeting on the subject of the uranium plant at Lansdowne and Dupont December 9-11, the commissioners ended up walking out.

The session, which was scheduled to run for three days but ended after two, was nothing short of historic. It was the first time in the plant’s 50-plus-year history that locals could air concerns to the regulator – an opportunity brought about solely because of grassroots pressure.
