SUMMARY

OF REQUEST:

On March 9, 2012, as supplemented March 13 and March 20, 2012, Mr. Paul Gunter, et. al.,

submitted a joint petition to the NRC, under Title 10 of the Code of FederalRegulations,Part 2.206, regarding James A. FitzPatrick Nuclear Power Plant (FitzPatrick).

The joint petitioners request that the FitzPatrick operating license be immediately suspended as the result of the undue risk to the public health and safety presented by the operator's reliance on non-conservative and wrong assumptions that went into the analysis of the capability of FitzPatrick's pre-existing ductwork containment vent system. The joint petitioners state that the risks and uncertainty presented by FitzPatrick's assumptions and decisions, in regard to NRC Generic Letter 89-16. as associated with the day-to-day operations of this nuclear power plant now constitute an undue risk to public health and safety. The joint petitioners request that the suspension of the operating license be in effect pending final resolution of a public challenge to the adequacy of the pre-existing vent line in light of the Fukushima PQaLiutDai-ichi nuclear accident. The joint petitioners do not seek or request that FitzPatrick operators now install the Direct Torus Vent System (DTVS) as it is demonstrated to have experienced multiple failures to mitigate the severe nuclear accidents at Fukushima Dai hiDai-ichi.

The joint petitioners request that the NRC take action to suspend the FitzPatrick operating license immediately until the following emergency enforcement actions are enacted, completed,

reviewed, and approved by the NRC and informed by independent scientific analysis:

1) Entergy Nuclear Operations' FitzPatrick nuclear power plant shall be subject to public hearings with full hearing rights on the continued operation of the Mark I BWR and the adequacy and capability of a pre-existing containment vent which is not a fully hardened vent line as recommended by NRC Generic Letter 89-16. As such, the FitzPatrick operator uniquely did not make containment modifications and did not install the DTVS, otherwise known as 'the hardened vent," as requested by NRC Generic Letter 89-16 and as installed on every other GE Mark I in the US;
2) Entergy Nuclear Operations shall publicly document for independent review its post-Fukushima re-analyses for the reliability and capability of the FitzPatrick pre-existing containment vent system as previously identified as "an acceptable deviation" from NRC Generic Letter 89-16 which recommended the installation of the Direct Torus Vent System and as outlined in the NRC Safety Evaluation Report dated September 28, 1992. The publicly documented post-Fukushima analysis shall include the reassessment of all assumptions regarding the capability and reliability of the pre-existing containment venting and specifically address non-conservative assumptions regarding:

a) the FitzPatrick cost-benefit analysis used to justify not installing a fully hardened vent system and; b) 'unlikely ignition points" as claimed in the FitzPatrick pre-existing vent line system that would otherwise present increased risks and consequences associated with the detonation of hydrogen gas generated during a severe accident.

In the March 20, 2012, supplement to the petition, the joint petitioners state that the Temporary Instruction 2515/183 provides the NRC inspection results in the "Follow-up to the Fukushima SDaih Dai-ichi Nuclear Station Fuel Damage Event." The joint petitioners draw attention to what is described at page 8 of the enclosure as an "apparentbeyond design and licensing basis vulnerability"involving the FitzPatrick operator's refusal to install the DTVS as recommended by NRC in Generic Letter 89-16.

To summarize the supplement, the joint petitioners state that:

  • The Commission's March 12, 2012, Order states that "Current regulatory requirement and existing plant capabilities allow the NRC to conclude that a sequence of events such as the Fukushima Dai-ichi accident is unlikely to occur in the US. Therefore, continued operation and continued licensed activities do not pose an imminent threat to public health and safety." The Order further states, "While not required, hardened vents have been in place in U.S. plants with BWR Mark I containments for many years but a wide variance exist with regard to the reliability of the vents."
  • The NRC inspection report identifies that FitzPatrck's "existing plant capabilities" and

.current procedures do not address hydrogen considerations during primary containment venting" which is further identified as a "current licensing basis vulnerability." The joint petitioners further reiterate that the NRC inspection finding that FitzPatrick's "existing plant capabilities" as assumed by the Order are in fact negated by the finding that "FitzPatrick's current licensing basis did not require the plant to have a primary containment torus air space hardened vent system as part of their Mark Icontainment improvement program."

2

" The Commission Order timeline setting December 31, 2016, for installing the reliable hardened vent does not address in a timely way the unique condition of FitzPatrick.

" FitzPatrick uniquely does not have a fully hardened vent system on the vulnerable Mark I containment. As a result, FitzPatrick's current capability is identified with "a beyond design and licensing bases vulnerability, in that FitzPatrick's current licensing basis did not require the plant to have a primary containment torus air space hardened vent system as part of their Mark I containment improvement program.' Given that the FitzPatrick unit willfully refused to install the DTVS, the documented discovery of the "licensing basis vulnerability" of its chosen pre-existing vent now uniquely warrants the suspension of operations pending closer scrutiny, public hearings, and full disclosure for its adequacy and capability in the event of a severe accident. The additional identified "vulnerability" and the relatively remote and uncertain mitigation strategy places the public health and safety unduly and unacceptably at risk by the continued day-to-day operations where "current procedures do not address hydrogen considerations during primary containment venting" and will not for nearly five (5) more years.

BASIS FOR THE REQUEST:

As a basis for the request, the joint petitioners' state that in light of the multiple failures of the GE Mark I containment and hardened vent systems at the Fukushima al iDai-ichi nuclear power station in the days following the March 11, 2011, station black out event, the joint petitions seek the prompt and immediate suspension of the FitzPatrick operations because:

" The GE Mark I BWR pressure suppression containment system is identified as inherently unreliable and likely to fail during a severe accident.

  • The capability of FitzPatrick's pre-existing containment vent as approved for severe accident mitigation is not a fully "hardened vent" system.

" The capability of FitzPatrick's pre-existing containment vent as approved relies upon non-conservative and faulty assumptions.

" The capability of FitzPatrick's pre-existing containment vent system uniquely allows for a severe nuclear accident to be released at ground level.

6 The Fukushima Dal' Dai-ichi nuclear catastrophe dramatically and exponentially changes the FitzPatrick cost-benefit analyses.

  • The continued day-to-day reliance upon the significantly flawed pre-existing containment vent system as would be relied upon to mitigate a severe accident at the FitzPatrick Mark I reactor presents an undue risk to the public health and safety.
  • The identified containment vulnerability, the non-conservative if not false assumption of "no likely ignition sources" in the pre-existing vent line and the unacceptable consequences of failure of the FitzPatrick pre-existing containment vent place both greater uncertainty and undue risk on public health and safety and are not reasonably justified by arbitrarily assigning a low probability of the occurrence of a severe accident.

IS THERE A NEED FOR IMMEDIATE ACTION: (If Yes, describe)

NO.

In its internal meeting on March 20, 2012, the PRB found that there is no immediate safety concern to FitzPatrick, or to the health and safety of the public and therefore, denied the request for emergency enforcement action based on the following considerations:

1. The Near-Term Task Force (NTTF), established by the NRC in response to the Fukushima Da~irh Dai-ichi nuclear event, concludes in its report dated July 12, 2011, that continued nuclear reactor operation and licensing activities do not pose an imminent risk to the public 3

health and safety and are not inimical to the common defense and security because of the low likelihood of an event beyond the design basis at a U.S, nuclear power plant and the current mitigation capabilities at those facilities:jhe Commission has endorsed the NTTF Formatted: Font: Not Bold, NlotHighlight Report, including its conclusions as evident by the Commission Voting Record for Decision Item SECY-11-0093, dated August 19, 2011: and,

2. On March 12, 2012, the NRC ordered licensees of BWR facilities with Mark I and Mark II containments to have reliable hardened containment vents (EA-12-050). This order was based on the Commission's direction provided by the Staff Requirements Memorandum (SRM) to SECY-12-0025, dated March 9, 2012. The order stated that:

Current regulatory requirements and existing plant capabilities allow the NRC to conclude that a sequence of events such as the Fukushima Dai-ichi accident is unlikely to occur in the U.S. Therefore, continued operation and continued licensing activities do not pose an imminent threat to public health and safety. However, the importance of reliable operation of hardened vents during emergency conditions was already well established and this understanding has been reinforced by the clear lessons of Fukushima. While not required, hardened vents have been in place in U.S. plants with BWR Mark I containments for many years but a wide variance exists with regard to the reliability of the vents. Additionally, hardened vents are not required on plants with BWR Mark 11containments although as discussed above, Mark I1containments are only slightly larger than Mark I. Reliable hardened venting systems in BWR facilities with Mark I and Mark 11containments are needed to ensure that adequate protection of public health and safety is maintained.

3._The NRC staff was aware of the conclusions presented in its Safety Evaluation (SE) dated September 28, 1992, for Fitzpatrick with respect to GL 89-16, and considered this information in its overall assessment on whether or not BWR facilities with Mark I and Mark L

theThe NRC inspected the design of the Fitzpatrick hardened wetwell vent system and documented the results in an inspection report (50-333195-06) issued April 18, 1995. The NRC staff was cognizant of and reviewed the results of inspections performed under TI 183 at FitzPatrick (Report dated May 13, 2011, ADAMS Accession No. ML111330455) following the events at Fukushima.

The design at Fitzpatrick is one example of that variance. The

'petition for emergency enforcement action provided no new additional information relating to the existing containment venting capability of the Fitzpatrick plant.

IS THERE A NEED FOR OE, 1, O.1G, or OGC INVOLVEMENT:

The petition does not contain any allegations of licensee or NRC staff wrongdoing. However, the PRB includes representatives from OE and OGC.

RECOMMENDED APPROACH AND SCHEDULE (Next Stepsl:

Accept, in part, and hold in abeyance the fWowiw-parts of the petition addressing containment venting under severe accident conditions and the design of vent systems being able to accommodate hydrogen gas (Issue Nos. 5(b), 7, and 11 in the Table) (see Table for a detailed explanation).

Three of the issues in the petition, identified and discussed as Issue Nos. 5(b), 7, and 11 in the Table, will be accepted for review by the NRC staff. However, as indicated in the Table, the NRC staff notes that these concerns are undergoing NRC review as part of the lessons-learned from the Fukushima event. Even though the Commission has issued the Order concerning Hardened-Ventreliable hardened vent for accident prevention, the NRC/JLD staff is conducting further review of additional aspects of the Hardcncd Vc.t Sycltmhardened vent system, such as flltratiG venting under severe accident conditions. In addition, the staff is evaluating hydrogen control and mitigation measures. Since Issue Nos. 5(b), 7, and 11 in the Table will take longer than the target timeframe for reaching a decision on a petition, the NRC plans on accepting those issues, and holding them in abeyance.

All the other issues in the petition, identified and discussed in the Table are denied for the reasons discussed in the Table The next steps would be to:

" Ensure management agrees with the PR6 initial recommendation.

  • Inform the petitioners of the PRB's initial recommendation.

" Provide the second opportunity for the petitioners to address the PRB, and make the arrangements for an acceptable date and time.

(1) The petition and the supplements do not include any new-or additional information or facts that were not known to the NRC staff with respect to FitzPatrick's Containment Vent System.

(2) FitzPatrick response to the GL 89-16 was also reviewed and approved by the NRC in September 1992, including the staff review of the licensee's processes and procedures, . _o_,_ _.No_ ,._or*,,_ . . .. ... . .

and inspections. The NRC staff evaluation stated, while approving FitzPatrick's positions with regard to GL-89-16, that FitzPatrick's containment vent system met the design bases and the design intent of GL 89-16. In addition, the NRC inspected the design of the Fitzpatrick hardened wetwell vent system and documented the results in an inspection report (50-333/95-06) issued Api1 18, 1995.

1 (3) Recommendation 5.1 orders licensees to include a reliabie hardened vent in BWR Mark I I and Mark Itcontainments- for prevention of core damage. This order included performance objectives for the design of hardened vents to ensure reliable operation and ease of use (both opening and closing) during a prolonged SBO. The staff is still evaluating on a neneric basis venting under severe accident conditions Recommendation 6 recommends, as part of the longer term review, that the NRC identify insights about hydrogen control and mitigation inside containment or in other buildings as additional information is revealed through further study of the Fukushima Dai-ichi accident. The staff is also evaluatinQ hydrogen control and mitigation on a generic basis.

(4) After the issuance of the Facility Operating License, the NRC has conducted its regular and necessary inspections and assessments of the licensee's performance. The Commission has not found it necessary to issue any g1o,1c cmrMunicatiO~c, based on thd *dust., opd- tingexp... en..,

or !he plant specific communications, based on the licensee's performance, to require any changes to the design and operating requirements of the Centainmont Vent Sy.tcm:containment vent system. The plant continues to meet all the requirements with respect to the regulations and the licensing bases, including those with respect to the design basis accidents and natural phenomena. Fukushima events have been characterized as "Beyond Design Basis Accidents." The design and operating requirements for "Beyond Design Basis Accidents" for Containment Vent System are being addressed through the Commission-Issued Order.
