SUBJECT:
POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2NRC INTEGRATED INSPECTION REPORT 05000266/2018002 AND 05000301/2018002 AND EXERCISE OF ENFORCEMENT DISCRETION
Dear Mr. Craven:
On June 30, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Point Beach Nuclear Plant, Units 1 and 2. On July 11, 2018, the NRC inspectors discussed the results of this inspection with you and other members of your staff.
The results of this inspection are documented in the enclosed report.
A violation of the licensees current site-specific licensing basis for tornado-generated missile protection was identified. Because this violation was identified during the discretion period covered by Enforcement Guidance Memorandum 15-002, Enforcement Discretion for Tornado Missile Protection Noncompliance, and because the licensee was implementing compensatory measures, the NRC is exercising enforcement discretion by not issuing an enforcement action for the violation and allowing continued reactor operation.
Based on the results of this inspection, the NRC has identified one issue that was evaluated under the risk significance determination process as having very-low safety significance (Green). The NRC has also determined that a violation is associated with this issue. Because the licensee initiated condition reports to address this issue, this violation is being treated as a Non-Cited Violation (NCV), consistent with Section 2.3.2 of the Enforcement Policy. This NCV is described in the subject inspection report.
If you contest the violation(s) or significance of the(se) NCV(s), you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region III; the Director, Office of Enforcement; and the NRC Resident Inspector at the Point Beach Nuclear Plant. If you disagree with a cross-cutting aspect assignment or a finding not associated with a regulatory requirement in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region III; and the NRC resident inspector at the Point Beach Nuclear Plant.
This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Enforcement
Discretion
Enforcement Action: EA-18-030: Unanalyzed
Condition for Tornado Generated Missiles
Description:
On June 10, 2015, the NRC issued Regulatory Issue Summary (RIS) 2015-06, Tornado
Missile Protection (ML15020A419), focusing on the requirements regarding tornado-
generated missile protection and required compliance with the facility-specific licensing basis.
The RIS also provided examples of noncompliance that had been identified through different
mechanisms and referenced Enforcement Guidance Memorandum (EGM) 15-002,
Enforcement Discretion For Tornado Generated Missile Protection Non-Compliance, which
was also issued on June 10, 2015, (ML15111A269) and revised on February 7, 2017,
(ML16355A286). The EGM applies specifically to a SSC that is determined to be inoperable
for tornado generated missile protection. The EGM stated that a bounding risk analysis
performed for this issue concluded that tornado missile scenarios do not represent an
immediate safety concern because their risk is within the LIC-504, Integrated Risk-Informed
Decision-Making Process for Emergent Issues, risk acceptance guidelines. In the case of
Point Beach, the EGM provided for enforcement discretion of up to three years from the
original date of issuance of the EGM.
The EGM allowed NRC staff to exercise this enforcement discretion only when a licensee
implements, prior to the expiration of the time mandated by the LCO, initial compensatory
measures that provided additional protection such that the likelihood of tornado missile effects
were lessened. In addition, licensees were expected to follow these initial compensatory
measures with more comprehensive compensatory measures within approximately 60 days of
issue discovery. The comprehensive measures should remain in place until permanent
repairs are completed, or until the NRC dispositions the non-compliance in accordance with a
method acceptable to the NRC such that discretion is no longer needed.
Table 1.3-1 of the Point Beach Final Safety Analysis Report (FSAR) states, in part, that
SSCs, which are essential to the prevention and mitigation of nuclear accidents, shall be
designed, fabricated, and erected to withstand the forces that might reasonably be imposed
by the occurrence of an extraordinary natural phenomenon, such as a tornado. On
March 1, 2018, the licensee initiated AR 02252240, identifying a nonconforming condition of
Table 1.3-1. Specifically, on both units 1 and 2, the steam supply lines and exhaust stacks
for the turbine-driven auxiliary feedwater pumps, the main steam isolation valves, the
atmospheric steam dumps, the main steam safety valves, and the vents for T-175B bulk fuel
oil storage tank were not adequately protected from tornado-generated missiles. The
licensee declared the affected SSCs inoperable and promptly implemented compensatory
measures designed to reduce the likelihood of tornado-generated missile effects.
The condition was reported to the NRC as Event Notice 53239 as an unanalyzed condition
and potential loss of safety function.
Enforcement discretion was previously authorized and documented in Inspection
Report 05000266/2018001 (ADAMS Accession Number ML18128A229).
Corrective Actions: The licensee documented the inoperability of the SSCs and the affected
TS LCO conditions in the CAP and in the control room operating log. The shift manager
notified the NRC resident inspector of implementation of EGM 15-002, and documented the
implementation of the compensatory measures to establish the SSCs operable but
nonconforming prior to expiration of the LCO required action.
The licensees immediate compensatory measures included:
review and revision of procedures for a tornado watch and a tornado warning to
provide additional instructions for operators preparing for tornados and/or high winds,
and a potential loss of SSCs vulnerable to the tornado missiles;
confirmation of readiness of equipment and procedures dedicated to the Diverse and
Flexible Coping Strategy (FLEX);
verification that training was up to date for individuals responsible for implementing
preparation and response procedures; and
establishment of a heightened station awareness and preparedness relative to
identified tornado missile vulnerabilities.
The licensees longer term compensatory measure was to modify AOP-13C, Severe
Weather Conditions procedure, to include actions for removing potential airborne hazards
and damage assessments for systems with a vulnerability to damage from tornado missiles.
Corrective Action Reference: AR 2252240
Enforcement:
Violation: The enforcement discretion was applied to the required shutdown actions of the
following TS LCOs for both units:
TS 3.0.3, General Shutdown LCO (cascading or by reference from other LCOs);
TS 3.7.1, Main Steam Safety Valves (MSSVs);
TS 3.7.2, Main Steam Isolation Valves (MSIVs) and Non-Return Check Valves;
TS 3.7.4, Atmospheric Dump Valve (ADV) Flowpaths;
TS 3.7.5, Auxiliary Feedwater (AFW);
TS 3.8.1; AC Sources Operating; and
TS 3.8.3, Diesel Fuel Oil and Starting Air.
Severity/Significance: The subject of this enforcement discretion, associated with tornado
missile protection deficiencies, was determined to be less than red (i.e., high safety
significance) based on a generic and bounding risk evaluation performed by the NRC in
support of the resolution of tornado-generated missile non-compliances. The bounding risk
evaluation is discussed in Enforcement Guidance Memorandum 15-002, Revision 1,
Enforcement Discretion for Tornado-Generated Missile Protection Non-Compliance, and can
be found in ADAMS Accession Number ML16355A286.
Basis for Discretion: The NRC exercised enforcement discretion in accordance with
Section 2.3.9 of the Enforcement Policy and EGM 15-002 because the licensee initiated
initial compensatory measures that provided additional protection such that the likelihood of
tornado missile effects were lessened. The licensee implemented more comprehensive
compensatory measures to address the nonconforming conditions within the required
days. These comprehensive actions are to remain in place until permanent repairs are
completed, which, for Point Beach, were required to be completed by June 10, 2018, or until
the NRC dispositioned the non-compliance in accordance with a method acceptable to the
NRC, such that discretion was no longer needed. On April 26, 2018, the licensee submitted a
request to extend the enforcement discretion in letter titled Request to Extend Enforcement
Discretion Provided in Enforcement Guidance Memorandum 15-002 for Tornado-Generated
Missile Protection Non-conformances Identified in Response to Regulatory Issues
Summary 2015-06, Tornado Missile Protection. On May 21, 2018, the NRC approved this
request and extended the enforcement discretion until June 10, 2020.
The disposition of this enforcement discretion closes LER 2018-001-00.

A Green finding and associated Non-Cited Violation (NCV) of Title 10 of the Code of Federal
Regulations (CFR) Part 50, Appendix B, Criterion III, Design Control, was identified by the
inspectors for the licensees failure to ensure that applicable regulatory requirements and
design basis, for structures, systems, and components, were translated into procedures.
Specifically, the licensee failed to include the floor plugs on the 26 level of the primary
auxiliary building (PAB) as credited flood barriers in procedure NP 8.4.7, PBNP Flooding
Program.
Description:
At approximately 10:00 a.m. on October 15, 2017, with Unit 1 shutdown and core defueling
in-progress, the licensee, in preparation for a Unit 1 RHR heat exchanger inspection,
removed a floor plug on the 26 level of the primary auxiliary building (PAB).
During a review of station logs, the inspectors noted that the licensee had removed the RHR
floor plug before the core was fully offloaded and asked the licensee if they had evaluated the
flooding implications of removing the floor plug. The licensee reviewed the issue and
concluded that they had created an unanalyzed flood path to the Unit 1 RHR pumps in the
lower level of the PAB.
At the time of the floor plug removal, the Unit 1 reactor cavity was flooded up to refueling
height and the core was in the process of being defueled with 69 of 121 fuel assemblies
removed from the core. LCO 3.9.4, Residual Heat Removal (RHR) and Coolant Circulation-
High Water Level, was applicable, and required that one RHR loop be operable and in
operation. The B RHR pump was running and operable and A RHR pump was considered
available. The mode of applicability for the Unit 1 RHR system ended at 12:40 a.m. on
October 16, 2017, when the core was completely defueled.
The inspectors reviewed the completed penetration permit for the floor plug removal and
identified a line item pertaining to flooding, which stated, Per NP 8.4.17, is this barrier
considered a flood barrier? If No, signature not required. The applicable line item on the
penetration permit was marked No. The inspectors reviewed NP 8.4.7, PBNP Flooding
Program, Revision 28, and found that the floor plug was not listed as a credited barrier in
Table 1, Flood Protection Features.
The licensee evaluated the new flooding pathway in a past operability determination and
found that, in multiple flooding events, flood waters reached both Unit 1 RHR pump rooms.
Overall, the licensee concluded that either the additional flood waters would have been
spread-out between the two Unit 1 RHR pump flood zones, with the worst-case scenario
having water levels just 1.3 under the 22 RHR operability limit for both pumps or the flood
waters would have accumulated in the B RHR pump room above the 22 operability limit and
resulted in the loss of the B RHR pump. The internal flooding analysis results with the floor
plug installed has both RHR pump rooms remaining dry with no flood waters reaching the
rooms.
Corrective Actions: The licensees corrective actions included painting a flood barrier
designator on each of the four floor plugs above the RHR heat exchangers and updating
procedure NP 8.4.17 to include the RHR floor plugs in Table 1, Flood Protection Features, as
having a flood barrier function.
Corrective Action Reference: Action Request 02230963, Flood Path to Unit 1 RHR Pump
Cubicles Created
Performance Assessment:
Performance Deficiency: The licensee failed to protect the Unit 1 RHR pumps from internal
flooding as required by the Final Safety Analysis Report section A.7, Plant Flooding, which is
a performance deficiency. Specifically, the licensee removed a floor plug, which created an
unanalyzed internal flood path from the 26 level of the primary auxiliary building (PAB) to the
Unit 1 RHR pump rooms.
Screening: The inspectors determined the performance deficiency was more than minor
because it adversely affected the design control attribute of the Mitigating Systems
Cornerstone and its objective of ensuring the availability, reliability, and capability of systems
that respond to initiating events to prevent undesirable consequences. Specifically, the
licensee created an unanalyzed flood path to the Unit 1 RHR pumps that allowed potential
flood waters to reach the Unit 1 RHR cubicles.
Significance: The finding affected the Mitigating Systems Cornerstone and was screened in
accordance with IMC 0609, Appendix G, Attachment 1, Shutdown Operations Significance
Determination Process Phase 1 Initial Screening and Characterization of findings. The
inspectors determined that the finding screened as potentially risk significant using the criteria
in Exhibit 5, External Events Screening Questions. Specifically, if the B RHR pump, which
was the operating pump, was assumed to be completely failed, a loss of decay heat removal,
which was a Table G1 event, would have occurred. Therefore, the inspectors answered Yes
to question 6 of Exhibit 3, Mitigating Systems Screening Questions, and screened the issue
to a detailed risk evaluation. The inspectors consulted the Region III SRA, who concluded
that the finding was of very low safety significance. Specifically, the short exposure time
coincident with Unit 1 being in plant operational state (POS) 3, resulted in the issue being of
very low safety significance. Plant operational state 3 represents the condition where
refueling cavity water level is at or above the minimum water level for movement of irradiated
fuel assemblies within the containment.
Cross-cutting Aspect: The inspectors determined this finding affected the Cross-Cutting area
of Human Performance in the aspect of Documentation, where the organization creates and
maintains complete, accurate and up-to-date documentation. Specifically, the licensee failed
to ensure that NP 8.4.17 was a complete and accurate procedure. NP 8.4.17, was not
complete and accurate because it contained an incomplete list of flood barriers used to
protect the safety-related RHR pumps. [H.7]
Enforcement:
Violation: Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires, in part,
that measures be established to assure that the design basis for safety-related functions of
SSCs are correctly translated into specifications, drawings, procedures, and instructions.
Contrary to the above, prior to June 19, 2018, the licensee failed to establish measures to
assure that the design basis for safety-related functions of SSCs are correctly translated into
specifications, drawings, procedures, and instructions. Specifically, the licensee failed to
include the RHR heat exchanger floor plugs as credited flood barriers in procedure NP 8.4.17,
PBNP Flooding Program, Revision 28.
Disposition: This violation is being treated as an NCV, consistent with Section 2.3.2 of the
71152Problem Identification and Resolution
Observation
71152 - Semi Annual Trend Review
During the course of the review period for this inspection sample, the inspectors noted several
examples where the licensee's implementation of NFPA 805 was less than adequate.
Although these errors did not result in any immediate significant safety consequences, a
potential trend in this area is apparent and suggests that additional licensee attention may be
appropriate. Specific examples associated with this trend included, but were not limited to:
April 12, 2017: the licensee determined that the breaker associated with a system
isolation valve was assumed open for their NFPA 805 assumptions (hot short
concern), but was found shut. A Green NCV was issued in Inspection Report 05000266/2017004 (ADAMS Accession Number ML18031B008).
March 13, 2018: while performing door inspections, the licensee determined 10 doors
did not meet the gap requirements for NFPA 805.
April 11, 2018: the licensee discovered that plant modifications installed to support the
fire protection transition to NFPA 805 did not address all necessary vulnerabilities.
The licensee had already secured the compensatory measures (fire watches.)
June 6, 2018: while investigating a deficient condition on a 480V MCC cabinet, the
licensee determined the cabinet did not meet the requirements of NFPA 805 for a
greater than 440V panel. An extent of condition identified a total of 27 cabinets with
this issue.
Each of the observations above represented failures of the licensees transition of their fire
protection program to NFPA 805 and were entered into their CAP. The licensee is aware of
the trend and is addressing it at a fleet level.
