2.206 Petition re: condenser tube degradation at FitzPatrick
Dear Mr. Borchardt:
Attached is a 10 CFR 2.206 petition submitted on behalf of the Alliance for a Green Economy, Beyond Nuclear, Citizens Awareness Network, and the Union of Concerned Scientists asking that the NRC take enforcement action to require that the degrading condenser tubes at the FitzPatrick nuclear plant be replaced prior to the unit restarting from its fall 2014 refueling outage.
We not not plan to also mail in a hard copy of this electronic version, but would be glad to do so upon request.

SUBJECT:
Recurring Condenser Tube Leaks and Petition Pursuant to 10 CFR §2.206 for the James A. FitzPatrick Nuclear Power Plant
Dear Mr. Borchardt:
On behalf of the Alliance for a Green Economy, Beyond Nuclear, Citizens Awareness Network, and the Union of Concerned Scientists, I respectfully submit this petition pursuant to 10 CFR
§2.206.
Each quarter, the Nuclear Regulatory Commission (NRC) staff places monthly operating data reports into the Agencywide Documents Access and Management System (ADAMS). For example, the reports for the first quarter of 2013 are in ADAMS at http://pbadupws.nrc, gov/docs/ML1312/ML13126A379.pdf. I read each of these reports and transfer items of interest into a database of events. These items include planned and unplanned reactor shut downs, reactor startups, and significant power reductions for non-routine maintenance and testing. Among the items are events when operators shut down a reactor or reduce its power level due to condenser tube leaks.
Condenser tube leaks are noteworthy for several reasons. The condenser is the normal heat sink for the heat produced by the reactor core when it is operating and when it is shut down.
Condenser tube leaks could cause the normal heat sink to become unavailable. The NRC's reactor oversight process recognizes the elevated risk associated with a reactor shut down with complications (see http://www.nrc.gov/NRR/OVERSIGHT/ASSESS/unplanned-scrams-with-complications.html). Condenser tube leaks could cause the normal heat sink to become unavailable which in turn can complicate the operator's response to a reactor shut down.
In addition, condenser tube leaks have caused extensive damage to nuclear plant components.
UCS described a September 1972 event at Millstone Unit 1 in a post to our blog (http://allthingsnuclear.org/fission-stories-3-high-tide-in-the-reactor/). This reactor was shut down for months while workers replaced components within the reactor vessel that had been damaged by sea water leaking in through failed condenser tubes.
Over the 43 months between January 1, 2003, and March 31, 2013, the operating data reports described 57 condenser tube events at U.S. nuclear power plants - an average of slightly over 1.3 events per month across the U.S. fleet.

July 25, 2013 Page 2 of 7 But the events are not scattered uniformly across this fleet. One reactor has experienced over 30 percent of condenser tube events in the past decade - the James A. FitzPatrick Nuclear Power Plant in your region. FitzPatrick has reported 18 condenser tube leaks. For comparison, the next highest number of events over this period is only three (a four-way tie among Comanche Peak Unit 2, Davis-Besse, Palo Verde Unit 1, and Turkey Point Unit 4).

The operators manually serumamed the reactor at 2:33 sn due to high conductivity in the hotwell caused by a suspected condenser tubeleak. Workers found that a deflector plate downstream of the IE-5B low pressure fcedwater heater dump valve CV-1340 broke Duane Arnold 20030201 IA loose and punctured a condenser tube and dented several other tubes. The deflector plate failed after approximately four months of continuous use of CV-1340 instead of the drain valve for heater level control.
July 25, 2013 Page 4 of 7 The evidence strongly suggests that (a) the condenser tubes at FitzPatrick are degrading, (b) the degradation rate is accelerating, and (c) the frequency of condenser tube events is increasing.
Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants, to 10 CFR Part 50 (see http://www.nrc.gov/reading-rm/doc-collections/cfr/partO5O/partO5O-appb.html) requires that plant owners develop and maintain quality assurance programs. This regulatory requirement explicitly states:
As used in this appendix, "qualityassurance" comprises all those plannedand systematic actions necessary to provide adequate confidence that a structure, system, or component will perform satisfactorily in service.
Sixteen condenser tube events at FitzPatrick during the 11 months from January 1, 2011 to March 31, 2013 is compelling empirical evidence that components are NOT performing satisfactorily in service. This unsatisfactory performance is made even more evident by the fact that no other nuclear power reactor in the United States is experiencing condenser tube events at even close to the frequency they are occurring at FitzPatrick.
Quite simply, the condenser tubes are wearing out at FitzPatrick. The NRC staff explained this aging phenomenon recently in their analysis of age-related incidents from licensee event reports and inspection findings between 2007 and 2011 (see http://pbadupws.nrc.gov/docs/ML1304/ML13044A469.pdf). This NRC memo contained the "bathtub curve."

July 25, 2013 Page 5 of 7 The increasing frequency of condenser tube events at FitzPatrick constitutes irrefutable evidence that these components are in the right-hand region of the bathtub curve where wear-out failures occur at increasing rates.
Your staff concedes this point and the owner's fault. In its report dated April 23, 2013, covering the biennial problem identification and resolution inspection at FitzPatrick (see http://pbadupws.nrc.gov/docs/ML 1211/M L 12114A279.pdf), the NRC staff stated:
The [NRC] team observed that Entergy did not properly considerFitzPatrickoperating history, specifically the 4 years of outages, when projectingthe expected condenser tube life. Consequently, Entergy did not properlyplan and designfor condenser tube replacementpriorto tube leakage which has necessitatedfrequentdownpowersfor repair.Plannedcorrective actions include condenser tube sleeving during the Fall 2012 refueling outage and a complete replacementof all condenser tubes in the Fall2014 refueling outage.
The track record for plant owners making good on their plans to implement safety fixes is mixed.
When safety fixes are not implemented on schedule, the public shoulders the burden from unnecessarily elevated risk.
On July 1, 2013, the NRC issued a confirmatory order (see http://adamswebsearch2.nrc.gov/webSearch2/main.isp?AccessionNumber='ML13114A928') to the owner of the Oconee nuclear plant. This order transformed the owner's previously stated plans for implementing safety upgrades into more enforceable regulatory requirements. In other words, the NRC must now formally review and approve any delays in completing the safety upgrades. Before this order, the owner could have unilaterally deferred completion deadlines.
While perhaps not posing the same heightened risk to the public as the safety shortcomings at Oconee, condenser tube degradation at FitzPatrick poses risks to the public. The plant's owner has plans to remedy this safety problem by replacing all the tubes during a refueling outage scheduled for fall of 2014. But the owner could readily - and without NRC approval - revise its plans to correct this problem at a later date.
Therefore, we petition the NRC under Section 2.206 to 10 CFR to take enforcement action' by imposing a regulatory requirement that all the condenser tubes be replaced at FitzPatrick prior to the reactor restarting from its fall 2014 refueling outage.
The enforcement action we request is needed to protect the public from the owner opting to defer correcting this safety problem. As the NRC has explicitly noted, the owner failed to "properly plan and design for condenser tube replacement" and is experiencing abnormally high occurrences of condenser tube failures. The fall 2014 refueling outage provides the owner with sufficient time to properly plan for the replacement of the degrading tubes. Any further delays
' The form of this enforcement action is up to the NRC: it could be via an order, or by amendment of the operating license to include a license condition, or any comparable means that result in the owner having to formally obtain NRC permission before operating FitzPatrick beyond its fall 2014 refueling outage without having replaced all its condenser tubes.
July 25, 2013 Page 6 of 7 would benefit the owner at the public's expense. Because this owner is clearly at fault (as the NRC has found), it is unfair for the public to continue picking up the tab for the owner's poor performance. If the owner does not replace the tubes during its refueling outage in fall 2014, than extending the downtime of the reactor until the replacements are finally completed would more equitably share the burden between the owner (who is at fault) and the public (which has no blame in this matter).
We, the petitioners, would like to exercise our right to address the NRC staff before the Petition Review Board (PRB) meets to consider our request. We believe we have clearly articulated the enforcement action we are requesting as well as its justification, but seek the pre-PRB meeting to highlight key issues as well as answer any clarifying questions the NRC staff may ask.
