The U.S. Nuclear Regulatory Commission (NRC) strives to establish and maintain an environment that

encourages all employees to promptly raise concerns and differing views without fear of reprisal and to

promote methods for raising concerns that will enhance a strong safety culture and support the agency's

mission.

Employees are expected to discuss their views and concerns with their immediate supervisors on a regular,

ongoing basis. If informal discussions do not resolve concerns, employees have various mechanisms for

expressing and having their concerns and differing views heard and considered by management.

Management Directive, MD 10.158, NRC Non-Concurrence Process, describes the Non-Concurrence

Process (NCP).

The NCP allows employees to document their differing views and concerns early in the decisionmaking

process, have them responded to (if requested), and include them with proposed documents moving

through the management approval chain to support the decisionmaking process.

NRC Form 757, Non-Concurrence Process," is used to document the process.

Section A of the form includes the personal opinions, views, and concerns of a non-concurring NRC

employee.

Section B of the form includes the personal opinions and views of the non-concurring employee's

immediate supervisor.

Section C of the form includes the agency's evaluation of the concerns and the agency's final position and

outcome.

NOTE: Content in Sections A and B reflects personal opinions and views and does not represent the

official agency's position of the issues, nor official rationale for the agency decision. Section C includes the

agency's official position on the facts, issues, and rationale for the final decision.

19. Reasons for the Non-Concurrence, Potential Impact on Mission, and the Proposed Alternatives

Background: Inspection Report 05000237/2020012 and 05000249/2020012 issued on May 19, 2020, included

Apparent Violation 05000237,05000249/2020012-02 for the licensee's failure to have a written evaluation which

provided the bases for determining a change made pursuant to 10 CFR 50.59(c) did not require a license

amendment. The inspection report cover letter requested the licensee to either attend a pre-decisional enforcement

conference or provide a written response to the NRC before the agency made a final enforcement decision for the

apparent violation. The licensee decided to provide a written response (ML20184A260) on July 2, 2020, which

included, among other items, the: (1) corrective steps taken and results achieved; (2) corrective steps that would be

taken; and (3) the date when full compliance was achieved. The statements below are excerpts from the licensee's

written response:

Corrective steps taken and results achieved -

This comprehensive reanalysis was then used to revise the 50.59 evaluation. As discussed below, the revised 50.59

evaluation concluded that these changes can be made without prior NRC approval. This revised 50.59 evaluation

corrects the documentation of the technical basis deficiency identified in the Apparent Violation.

Corrective steps that will be taken -

In addition to the comprehensive reanalysis of the UHS and the revised 50.59 evaluation, several additional actions

were identified in the CAPE. Additional actions that will be completed are not corrective actions directly related to

restoring compliance for the Apparent Violation; these actions are enhancements that ensure organizational learning

from this event.

Date when full compliance will be achieved -

Full compliance was achieved on June 29, 2020. The 10 CFR 50.59 Evaluation 2020-02-001, Revision 1 has been

approved. The revision was supported by the comprehensive UHS reanalysis and provided the documented technical

basis.

Through a review of 10 CFR 50.59 Evaluation 2020-02-001 (the licensee's corrective action intended to restore

compliance for the Apparent Violation) and supporting analyses for the evaluation, I determined the evaluation did NOT

restore compliance because it did not appropriately consider the design and licensing basis of the facility. After consulting

with my management, I reached out to the licensee on July 16, 2020, to ensure a common understanding of the facility

design and licensing basis. At that time I was informed by the licensee that they disagreed with my understanding of the

facility's design and licensing basis, and that they believed they had appropriately considered it when completing 10 CFR

50.59 Evaluation 2020-02-001. I then reached out to the Division of Reactor Oversight in the Office of Nuclear Reactor

Regulation and they agreed with my conclusion on the facility's design and licensing basis.

Two post licensee response panels were held on August 13 and August 20, 2020, to make a final enforcement decision for

the apparent violation. At the conclusion of the panel on August 20, 2020, the panel members agreed the apparent

violation would be characterized as a SLIV violation and that it would be dispositioned as a Notice of Violation (NOV)

because the licensee had not restored compliance. Subsequent to that, the Deputy Division Director of the Division of

Reactor Safety in Region III expressed a concern with issuing the SLIV violation as a NOV. I agreed the SLIV violation

could be issued as a Non-Cited Violation (NCV) as long as Enforcement Discretion was granted because the criteria for

issuing a NCV in accordance with Section 2.3.2.a of the Enforcement Policy were NOT met.

Reasons for the Non-Concurrence: The current version of the document dispositions the SLIV violation as a NCV

without using Enforcement Discretion. The reason provided in the document for issuing a NCV is the following:

"Because you [licensee] initiated condition reports demonstrating objective evidence of plans to restore

compliance, the violation is being treated as a Non-Cited Violation (NCV) consistent with Section 2.3.2 of the

Enforcement Policy."

After reviewing the licensee's written response, supporting analyses and evaluations, and multiple corrective action

documents associated with the violation, I determined the licensee had NOT restored compliance for the violation

identified. Since this letter (subject of this non-concurrence) provides the final enforcement decision for the apparent

violation, it must disposition the violation using the corrective action information available to the agency at this time.

Therefore, while the statement above could've been used to disposition the violation as a NCV before July 2, 2020

(before the licensee's written response was received), it is no longer factual because we now know the licensee's

plans were NOT successful in restoring compliance. Furthermore, I reviewed currently open corrective actions

associated with the violation and did NOT identify any objective evidence of plans for restoring compliance. The fact

that the agency opened up Enforcement Action #EA-20-120 to track an additional issue of concern I identified while

reviewing the licensee's written response is further evidence that at an agency level, we are not confident the

licensee will appropriately restore compliance because they don't understand their design and licensing basis.

To conclude, I am non-concurring on the document because I disagree with the basis provided for dispositioning the

violation as a NCV. I do NOT believe the SLIV violation documented in the letter meets the NCV criteria in Section

2.3.2.a of the Enforcement Policy, for the reasons stated above.

Potential Impact on Mission: The potential impact of the decision to disposition the violation as a NCV is that an

established agency position is being created with regards to the licensee's corrective actions taken. Specifically,

since the agency is already aware of the outcome of the licensee's corrective actions taken to restore compliance,

the agency is tacitly approving those actions by stating we have objective evidence of plans that would restore

compliance. Proceeding with a NCV will unnecessarily create a "Backfit" potential when trying to address the issue

of concern related to the licensee's Ultimate Heat Sink design and licensing basis. I believe the safety significance of

that issue of concern is greater than the significance of the violation being dispositioned, and appropriately resolving

that issue of concern is in the best interest of public health and safety.

Proposed Alternatives:

1. Keep the Apparent Violation open until further inspection is completed to resolve the additional issue of

concern identified related to the Ultimate Heat Sink Design and Licensing Basis, then disposition both issues

in the same inspection report.

2. Issue the Apparent Violation as a SLIV NOV in accordance with the Enforcement Policy.

3. Issue the Apparent Violation as a SLIV NCV w/ Enforcement Discretion in accordance with the Enforcement

Policy.

8. Agreed Upon Summary of Issues

On May 19, 2020, the NRC issued report 05000237/2020012 and 05000249/2020012 to Dresden Nuclear

Power Station Units 2 and 3. This report contained a Green finding and associated Non-cited Violation

(NCV) of 10 CFR 50, Appendix B, Criterion III, "Design Control," and an Apparent Violation (AV) of 10 CFR

50.59, "Changes, Tests, and Experiments."

The AV was a result of the licensee's failure to have a written evaluation which provided the bases for

determining a change made pursuant to 10 CFR 50.59(c) did not require a license amendment.

Specifically, the licensee approved a change to the Updated Final Safety Analysis Report (UFSAR) which

reduced the Ultimate Heat Sink (UHS) coping time from four days to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and UHS volume capacity

from two million gallons to one million gallons. This evaluation failed to provide a basis for the determination

that the change would not result in more than a minimal increase in the likelihood of occurrence of a

malfunction of the Diesel Generator Cooling Water (DGCW) system previously evaluated in the UFSAR.

The inspectors concluded the licensee should have obtained a license amendment prior to implementing

the proposed change to the UHS required volume and its associated coping time as discussed in the

UFSAR. Prior NRC approval is required for changes resulting in more than a minimal increase in the

likelihood of occurrence of a malfunction of a structure, system, or component (SSC) important to safety

previously evaluated in the USFAR.

The ROP's significance determination process does not specifically consider the regulatory process impact

in its assessment of licensee performance. Therefore, it is necessary to address this violation, which

impedes the NRC's ability to regulate, using traditional enforcement. Section 6.1.d.2 of the Enforcement

Policy states that violations of 10 CFR 50.59 resulting from conditions evaluated as having very low safety

significance (i.e., green) by the Significance Determination Process (SDP) should be assigned SLIV

significance. However, section 2.1.3.D.5 of the Enforcement Manual states that violations will normally be

categorized at SLIII if the activity or change required prior NRC approval and the NRC was not likely to

approve the change. This section of the Enforcement Manual also states that the Region should convene

an enforcement panel to discuss the issue. An enforcement panel was held on April 16, 2020, and the

panel decided to issue the 50.59 violation, which had very low safety significance (i.e., green), as an AV

that requested a written response before a final NRC determination. The inspection report containing the

AV was issued on May 19, 2020.

The licensee provided a written response to the AV on July 2, 2020. In this response, the licensee stated

its position on the: (1) corrective steps taken and results achieved; (2) corrective steps that would be taken;

and (3) the date when full compliance was achieved. In addition, the licensee provided its reanalysis of the

UHS capacity calculation and procedural enhancements to replenish the UHS following a postulated failure

of the Dresden Lock and Dam. The licensee stated that the procedure revision was supported by the

comprehensive UHS reanalysis and provided the documented technical basis. This reanalysis credits 1.8

million gallons of UHS volume and a 3.7-day coping time. The licensee concluded that the revised 50.59

evaluation did not require prior NRC approval.

The inspector reviewed the licensee's response and concluded that the licensee did not restore compliance

to the AV because the licensee did not appropriately evaluate changes to the design and licensing basis of

the facility in the revised 50.59 evaluation. Specifically, the 10 CFR 50.59 Evaluation 2020-02-001,

Revision 1, dated June 29, 2020, evaluated a failure of a dam and indicated that it did not need to consider

the additional/coincident impacts of a Loss of Offsite Power (LOOP). Prior to that evaluation, the licensing

basis indicated that both events could occur simultaneously. The inspector concluded that 10 CFR 50.59

Evaluation 2020-02-001, Revision 1 effectively changed the licensing basis by removing a coincident

LOOP from a dam failure, which would create a possibility for a malfunction of an SSC important to safety

with a different result than any previously evaluated in the final safety analysis report [10 CFR 50.59(c)(2)

(vi)]. Specifically, a malfunction of the offsite power system during a dam failure event would now cause an

unanalyzed condition to exist because operation of the EDGs during the event was not considered or

evaluated. Consequently, the inspector believes the licensee's revised 50.59 evaluation does not restore

compliance because it is not a written evaluation which provides the bases for determining the change

(removal of the LOOP from the dam failure event) made pursuant to 10 CFR 50.59(c) did not require a

license amendment

During the review of the licensee's response to the 50.59 AV, an additional and separate Issue of Concern

(IOC) was identified for the licensee's 2012 approval of a change to its UFSAR which removed seismic

dam failure (i.e., a dam failure resulting from a seismic event) from the design and licensing basis. This

removal was done through a 50.59 screening and was never evaluated in accordance with 10 CFR

50.59(c). The inspector determined this change should also have been evaluated in accordance with 10

CFR 50.59(c) and would have required prior NRC approval.

Neither the licensee's removal of the LOOP coincident with a dam failure (in 2020) nor the removal of the

seismic event coincident with a dam failure (in 2012) have been formally dispositioned to the licensee as

performance deficiencies. Both issues have been informally communicated to the licensee by the inspector

and the branch chief responsible for the inspection activities.

On August 13, 2020, a second enforcement panel was held to discuss the licensee's response. No

decision was made at this meeting. On August 20, 2020, a third enforcement panel was held. During this

meeting, the Office of Enforcement (OE) informed the panel members that the guidance in section

2.1.3.D.5 of the Enforcement Manual (associating a SLIII significance to a 50.59 violation that would have

required prior NRC approval and would likely not have been approved by the NRC) was incorrect. OE

stated that the guidance in the Enforcement Policy should have been used and a SLIV significance should

be assigned to the 50.59 violation. The panel agreed the dam failure due to a seismic event and LOOP

was in the licensee's licensing basis and that no corrective action credit would be provided because the

licensee did not believe a LOOP and/or a seismic event coincident with a dam failure was in its design and

licensing basis. Therefore, the panel decided to issue the 50.59 violation as a SLIV with a Notice of

Violation (NOV) because the updated 50.59 erroneously failed to consider the coincident effects of a LOOP

and dam failure, which was within the licensing basis, and, therefore, did not correct the underlying

noncompliance. The panel also appeared to recognize the 2012 issues with respect to the seismic failure

of a dam.

Following the third enforcement panel, the R3 Deputy Director (DD) of the Division of Reactor Safety (DRS)

continued to have communications with OE and other members of the enforcement panel regarding the

characterization of the 50.59 violation as a NOV. The DDDRS felt uncomfortable with the NOV

classification and felt the issue should be treated as a Noncited Violation (NCV). A NCV is a nonrecurring,

typically non-willful, SLIV violation or a violation associated with a Green ROP finding that is not subject to

formal enforcement action if, for a reactor licensee, the licensee places the violation in a corrective action

program to address recurrence and restores compliance within a reasonable period of time. During these

communications, the panel members agreed to issue the violation as a SLIV NCV because they believe the

licensee was acting in good faith at the time of its submittal, some of the corrective actions the licensee had

taken were improvements to the issue that the NRC identified during the 2020 UHS inspection, and the

licensee's response would have brought the site into compliance based on the licensees understanding of

their licensing and design basis. Specifically, the DDDRS believes the 2012 50.59 IOC has a cascading

effect in the history of licensee's design and licensing basis. Until the NRC formally inspects the 2012 IOC

and communicates any potential non-compliances to the licensee, the licensee's perspective of its

restoration of compliance to the AV is impacted. If the 2012 50.59 evaluation is determined to be

inadequate due to the removal of a seismic dam failure, the licensee would be required to review any other

evaluations that assumed seismic dam failure was not required and correct them to remain in compliance.

The inspector believes the 50.59 violation cannot be dispositioned as an NCV unless enforcement

discretion is applied. Section 2.3.2 of the Enforcement Policy states that for licensees that have

implemented a corrective action program that is determined to be adequate by the NRC, the NRC will

normally disposition SLIV violations and violations associated with green ROP findings as NCVs if all the

criteria in Paragraph 2.3.2.a. are met. Section 2.3.2.a states:

  • The licensee must place the violation into a corrective action

program to restore compliance and address recurrence.

  • The licensee must restore compliance (or demonstrate objective

evidence of plans to restore compliance) within a reasonable period of time (i.e.,

in a timeframe commensurate with the significance of the violation) after a

violation is identified.

  • For traditional enforcement, the violation must either not be repetitive as a result

of inadequate corrective action, or, if repetitive, the repetitive violation must not

have been identified by the NRC. This criterion does not apply to violations

associated with green ROP findings.

  • The violation must not be willful.

After reviewing the licensee's response to the AV, the inspector believes the licensee has not restored

compliance or demonstrated objective evidence of plans to restore compliance. Specifically, in its

corrective actions to restore compliance to the AV, the licensee effectively changed the licensing basis by

removing a coincident LOOP from a dam failure, which would create a possibility for a malfunction of an

SSC important to safety with a different result than any previously evaluated in the final safety analysis

report. The inspector acknowledges that resolving the 2012 50.59 IOC may eventually lead to correction of

this issue. However, the inspector believes the removal of a LOOP coincident with a dam failure is a

separate performance deficiency that, standing alone, was inappropriately removed from the licensee's

design and licensing basis in 10 CFR 50.59 Evaluation 2020-02-001, Revision 1, dated June 29, 2020, the

corrective action for the AV. The inspector believes, as documented in the licensee's written response to

the AV dated July 2, 2020 and through a review of open CAP documents related to the issue, that the

licensee has completed its corrective actions associated with restoring compliance to the AV. The

inspector also believes the licensee will not take additional corrective actions until it has been formally

communicated to the licensee that those corrective actions did not restore compliance to the AV. On

November 17, 2020, the licensee submitted a condition report acknowledging gaps in the documentation of

the 2012 50.59 IOC which was identified during the review of the licensee's AV response. However, this

CR appears to not address the inspectors concerns regarding restoring compliance to the 2020 AV.

Specifically, the licensee states that the 10 CFR 50.59 Evaluation 2020-02-001 Revision 1, dated June 29,

2020, which they had previously indicated restores compliance to the AV, removed the discussion of LOOP

in UFSAR Section 9.2.5.3.1, and that no additional evaluations are required. The inspector believes the

licensee's assertion that no additional evaluations is further evidence that no additional corrective actions

will be undertaken to restore compliance for the AV.

The inspector feels that characterizing the 50.59 violation as an NCV is not consistent with the Enforcement

Policy and that a NOV characterization is appropriate. The inspector believes that issuing the 50.59

violation as an NCV would be appropriate if enforcement discretion was applied to acknowledge the

perceived deviation from the NCV criteria in the Enforcement Policy. The inspector offered an additional

outcome which would keep the AV open until further inspection is completed to resolve the additional IOC's

related to the UHS design and licensing basis, then disposition all issues in the same inspection report.

In addition to the inspector's belief that issuing the 50.59 violation as a NCV is inconsistent with the

Enforcement Policy, the inspector's major concern is that dispositioning the violation as an NCV has the

potential of establishing an agency position regarding the licensee's corrective actions taken. Specifically,

since the agency is already aware of the outcome of the licensee's corrective actions taken to restore

compliance, the agency is tacitly approving those actions by stating the licensee-initiated condition reports

demonstrating objective evidence of plans to restore compliance. Proceeding with an NCV will

unnecessarily create a "Backfit" potential when trying to address the IOC related to the licensee's Ultimate

Heat Sink design and licensing basis.

9. Evaluation of Non-Concurrence and Rationale for Decision

The DRE 50.59 UHS AV has been the subject of three enforcement panels. The third panel concluded to

issue the 50.59 AV as a SLIV NOV. Following this last panel, the DDDRS continued to have

communications with panel members and OE to discuss the appropriateness of NOV classification. During

these communications, it was decided that there was flexibility in the Enforcement Policy to support the

50.59 AV to be issued as an NCV. Specifically, to receive the NCV classification, the licensee must enter

the issue into its CAP and restore compliance (or demonstrate objective evidence of plans to restore

compliance) within a reasonable amount of time. The licensee has entered this issue into its CAP and the

licensee believes it has restored compliance based in its understanding of its UHS design and licensing

basis. The potential performance deficiencies identified during the NRC's review of the licensee's response

to the 50.59 AV have not been formally communicated to the licensee. Once the IOC's that were identified

during the review of the licensee's response to the AV are inspected and the results are formally

communicated to the licensee, the NRC can take enforcement actions as appropriate.

In response to the inspector's potential backfit concern, the DDDRS believes the letter, which is the basis

for this non-concurrence, does not take a position on whether the licensee has restored compliance for the

AV. The DDDRS believes the licensee should be notified with a separate violation and provided the

opportunity to respond if the NRC determines that removal of the LOOP coincident with a dam from the

licensee's design and licensing basis was done inappropriately. The letter explicitly states staff's view that

the response provided by the licensee raised an issue of concern about Dresden's licensing basis that will

be followed-up on during future inspection activities. This assertion, accompanied by the inherent nature

and flexibility of the NRC's approach to its risk informed inspection program, leads the DDDRS to believe

future inspections or future potential non-compliances related to the licensee's UHS design and licensing

basis would not be impeded.

The DDDRS considered the inspector's concerns associated with the classification of the 50.59 AV as an

NCV and has taken the inspector's proposed recommendations into careful consideration. Although the

inspector's proposed outcomes were not taken, those alternate views added depth and perspective to the

decision-making process. All parties acknowledge the complexity of this issue and feel that their respective

positions support safety. This issue helped identify a discrepancy in the Enforcement Manual. There are

current agency efforts in progress seeking Commission approval on gaining alignment with the

Enforcement Policy and Enforcement Manual. There are additional agency efforts in progress reviewing

the Significance and Enforcement Review Panel (SERP) process. Both initiatives could add clarity to future

similar issues. Although the decision regarding the approach in issuing the 50.59 AV as an NCV without a

deviation is not uniformly agreed upon, this approach is acceptable, meets the Enforcement Policy, and the

effort towards resolution may directly and indirectly improve how these types of issues are handled in the

future.
