DEK Considerations in Response to O d EA 12 049 d 051 Orders EA-12-049 and 051 NRC Public Meeting November 27, 2012 Kewaunee Power Station (KPS)
Kewaunee Power Station (KPS)
Dominion Energy Kewaunee, Inc.
(DEK)
(DEK)
Purpose
- Kewaunee transition to permanent shutdown announced
- Explore options to ensure compliance with orders if orders, if
- Full power on February 28 submittal date Defueled in advance of December 2016
- Defueled in advance of December 2016
- Receive feedback from NRC 2
Major Milestones Milestone Date Submit Overall Integrated Plan Feb 2013 Shutdown and Defueled Expected 2Q 2013 First Six-month Update Aug 2013 First Six month Update Aug 2013 Order Compliance Dec 2016 3
Activities For Permanent Shutdown
- DEK notified NRC on 11/2/12 of decision to permanently cease operation p
y p
- Pending transmission operator review, shutdown expected in 2Q 2013 shutdown expected in 2Q 2013 4
Long Term Fuel Strategy
- Fuel must remain in the spent fuel pool (SFP) for about eight years
(
)
g y
- Logical progression to dry cask storage 5
Major Impact
- SFP cooling only function relevant in orders
- Time to boil (TTB) increases significantly Time to boil (TTB) increases significantly
- At 12/31/16, TTB about 187 hours0.00216 days <br />0.0519 hours <br />3.091931e-4 weeks <br />7.11535e-5 months <br /> 6
Order EA-12-049 Mitigation Strategies Order EA-12-049 Mitigation Strategies for BDB External Events
- Applicable strategies when plant ceases operation
- Functions of containment cooling and core cooling are not required after defueling S
f l
l li b
i i
d
- Spent fuel pool cooling must be maintained while heat load decays until dry storage
- Decay heat load approaches steady state Decay heat load approaches steady state
- Commercially available, portable equipment is adequate as backup 7
Order EA-12-051 Reliable Spent Order EA 12 051 Reliable Spent Fuel Pool Instrumentation
- Currently use narrow range with local indication and control room alarm
- Periodic verification of level preformed using existing instrumentation g
- Response required for the applicable external event is long term g
- Many days available for response with onsite staff
- Level constant for about 187 hrs (7.8 days) 8

Overall Integrated Plan
- DEK will submit overall integrated plan on Feb 28, 2013 for both Orders
- Proposed approach:
- Alternative approach to NEI 12-06 and 12-02
- High level plan appropriate for an operating unit; and
- A detailed plan reflecting a permanently defueled unit with implementation in December 2016 9
