PLANT STATUS
The unit remained at or near full power for the entirety of the inspection period.
On April 25, 2018, FirstEnergy Solutions (FES) / FirstEnergy Nuclear Operating Company
(FENOC) notified the U.S. Nuclear Regulatory Commission (NRC) that they intend to shut down
all four of their operating nuclear power plants (ADAMS Accession Number ML18115A007).
Based on that notification, the first to shut down will be Davis-Besse, by May 31, 2020. On
March 31, 2018, FES, FirstEnergy Nuclear Generation (FENGEN), and FENOC filed for
bankruptcy. The NRC continues to maintain focus on public health and safety and the
protection of the environment. This will include a continuous evaluation by inspectors to
determine whether the licensees financial condition is impacting safe operation of the plant.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in
effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with
their attached revision histories are located on the public website at http://www.nrc.gov/reading-
rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared
complete when the IP requirements most appropriate to the inspection activity were met
consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection
Program - Operations Phase. The inspectors performed plant status activities described in
IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem
Identification and Resolution. The inspectors reviewed selected procedures and records,
observed activities, and interviewed personnel to assess licensee performance and compliance
with Commission rules and regulations, license conditions, site procedures, and standards.

Confirmatory Orders
On September 1, 2016, Confirmatory Order EA-16-022 (ADAMS Accession Number
ML16245A488) was issued by the NRC to the licensee as the result of a settlement reached
during a successful Alternative Dispute Resolution (ADR) session conducted on July 21, 2016.
Additional details of the apparent violations associated with this ADR are documented in NRC
Inspection Report 05000346/2016008 and Investigation Report No. 3-2015-009.
This inspection was conducted in accordance with IP 92702, Follow Up on Traditional
Enforcement Actions Including Violations, Deviations, Confirmatory Action Letters, Confirmatory
Orders, and Alternative Dispute Resolution Confirmatory Orders. The inspection objective was
to determine that adequate corrective actions have been implemented and maintained for
enforcement actions.
The inspectors reviewed the licensees responses to the Confirmatory Order to ascertain that
the licensees responses and stated corrective and preventative actions were timely and
appropriate.
The licensee documented the associated responses to the Confirmatory Order in Request
to Close Commitment Tracking Item reports DB-EA-16-022-01, DB-EA-16-022-02,
DB-EA-16-022-03, DB-EA-16-022-04, DB-EA-16-022-05, DB-EA-16-022-06,

The inspectors determined that the licensees responses to the Confirmatory Order and stated
corrective and preventative actions were timely and appropriate.
No findings were identified.
Evaluation of Davis-Besse Safety Condition in Light of Financial Conditions
The licensees parent company, FirstEnergy Solutions, was under bankruptcy
protection/reorganization during the inspection period. As such, NRC Region III conducted
special reviews of processes at Davis-Besse. Using the flexibilities in the baseline inspection
program, the inspectors evaluated several aspects of the licensees operations to assess
whether any identified plant performance issues could be related to the stations financial
condition. The factors reviewed included: (1) impact on regulatory-required plant staffing;
(2) corrective maintenance backlog; (3) changes to the planned maintenance schedule;
(4) corrective action program implementation; and (5) reduction in outage scope, including
risk-significant modifications. In particular, the inspectors verified that licensee personnel
continued to identify problems at an appropriate threshold and enter these problems into the
corrective action program for resolution. The inspectors also verified that the licensee continued
to develop and implement corrective actions commensurate with the safety significance of the
problems identified.
The review of processes at Davis-Besse included continuous reviews by the Resident
Inspectors, as well as the specialist-led baseline inspections completed during the inspection
period which are documented previously in this report.
INSPECTION RESULTS
71152Problem Identification and Resolution
Observation-Selected Issue Follow Up for EN-DP-02511: 71152Annual Sample
Follow-Up Review of Licensee Periodic Shield Building Core Review
Bore Visual Examinations for Concrete Laminar Cracking
As part of the continued long term monitoring of the shield building laminar cracking condition
documented in inspection report (IR) 05000346/2014008 (ADAMS Accession Number
ML15148A489), the licensee subjected a sample of existing shield building core bores to
visual examination as prescribed by licensee procedure EN-DP-01511, Structures
Monitoring. One purpose of the core bore visual examinations conducted under this
procedure was to determine if any growth or change in the nature of the cracks had occurred
by measurement of crack width and comparison to historical values. In areas of identified
laminar crack planar propagation, additional impulse response mapping is performed to
provide a relative indication of the extent of propagation.
During the course of this in-depth review, the inspectors verified the status of the licensees
core bore visual examinations, as well as their evaluations and corrective action documents
resulting from shield building laminar cracking not identified by previous visual examinations.
In addition, the inspectors reviewed the licensee's plans for follow-on examinations and
corrective actions that had been established to verify that the classification, prioritization,
focus, and timeliness of these actions were commensurate with the safety significance of the
issue.
During the 2018 periodic examination, the licensee identified additional growth in laminar
crack width and documented the growth in the corrective action program. In some instances,
the measured laminar crack width exceeded the crack widths induced during testing
previously performed at selected universities referenced in IR 05000346/2014008 to credit full
reinforcement capacity in those areas. Laminar crack propagation was also observed at
some locations based on visual examination and was similar to the predicated propagation
pattern.
As a result of the increased crack width, the licensee performed operability evaluations of the
shield building and determined that the shield building remained operable based on the
increased crack widths being localized in nature and engineering calculations that
conservatively assume reinforcement is not effective in areas of laminar cracking. The
inspectors reviewed the licensees operability determinations and determined as reasonable
the licensees assessment that the shield building remained capable of performing its
intended safety function.
Corrective actions completed or planned to date include, but are not limited to, concrete
removal and repair, and rebar inspection at two locations to determine the corrosion potential
of the shield building reinforcement; concrete removal and repair to remove the shoulder at
one location, and development of a comprehensive plan for re-establishing shield building
conformance to the design and licensing basis of the facility with the increase in crack widths.
As a result of the observed increases in laminar crack width, the licensee postponed its
planned license amendment submittal to allow time for additional analysis and development of
potential mitigation strategies.
Observation-Selected Issue Follow-Up for CR 2016-09073 71152Annual Sample Review
and CR 2017-07832: Follow-Up Review of Licensee
Corrective Actions Related to Identified Shield Building
Laminar Cracking
The inspectors reviewed licensee corrective action activities associated with the removal and
repair of concrete for rebar inspection to determine the corrosion potential of the shield
building reinforcement.
As documented in CR 2016-09073 (shield building shoulder 13, bore S13-631.0-8), the
licensee identified laminar crack growth including crack width that exceeded bounds of this
parameter in tests that determined rebar splice strength. As a result, the licensee initiated
Engineering Change Package (ECP) 17-0211-000, "Shield Building Concrete Removal and
Repair for Rebar Inspection," to determine the corrosion potential of the shield building
reinforcement. The inspectors reviewed and observed a sample of licensee documents and
activities for concrete removal and repair at shoulder 13 including:
- ECP 17-0211-000 allowed shield building concrete removal and repair during plant
operation. At shoulder 13, ECP 17-0211-000 removed a portion of shield building
exterior concrete that was approximately 12.5 feet around the circumference
(horizontal), 50 feet in height (vertical), and of varying depth to allow examination for
rebar corrosion and to provide adequate bonding between replacement concrete and
rebar. The inspectors reviewed licensee calculations that demonstrated that the shield
building would be capable to perform its design basis safety functions throughout the
concrete removal and repair activity. Specifically, the inspectors reviewed calculations
that demonstrated the shield building maintained adequate radiation shielding, barrier
protection for tornado missiles, and structural capacity during an earthquake while in a
degraded condition with concrete removed.
- The inspectors verified that removal and repair of concrete was performed in
accordance with licensee procedures and industry standards. In particular, the
inspectors verified concrete excavation beyond structural rebar was sufficient to
ensure adequate bonding between the replacement concrete and rebar.
- The inspectors directly observed a portion of exposed rebar during concrete removal.
Inspectors noted evidence of rebar corrosion. The inspectors reviewed the licensee's
criteria to remove and replace corroded rebar, the method to splice replacement rebar
to existing rebar, and the test results that demonstrated rebar design strength would
be achieved for mechanical splice components used in the repair.
- The inspectors directly observed licensee activities during one concrete replacement
pour including testing of concrete prior to installation. Specifically, the inspectors
observed that only concrete within slump, air entrainment, and temperature test
acceptance ranges was installed. The inspectors also observed concrete placement
into cylinders segregated for later testing to verify 28-day design compressive
strength.
- Finally, the inspectors reviewed test reports that demonstrated the installed concrete
cured to the 28-day minimum design compressive strength for each separate concrete
pour.
As documented in CR 2017-07832, Exterior Surface Crack on Shoulder 10, the licensee
identified a new vertical crack. As a result, the licensee initiated Design Change Package
engineering change (EC) 18-0037-002, Shield Building Shoulder 10 Removal, to remove
existing laminar cracking in shoulder 10 in addition to the vertical crack. As indicated in
EC 18-0037-002, the repairs on shoulder 10 are to be performed while the unit is at power,
and the Shield Building is required to be capable of performing its design functions within
operability limits. Also indicated in EC 18-0037-002, when repairs are made to shoulder 10,
the concrete will be restored to a cylindrical section without the shoulder.
At the time of this inspection, the licensee had not completed shoulder 10 repair activities
associated with EC 18-0037-002. The inspectors reviewed a sample of licensee documents
and activities for concrete removal and repair at shoulder 10 including:
- The inspectors reviewed the licensees interim calculation that evaluated the shield
building's operability during the remediation process assuming the worst case scenario
of maximum area of concrete removed to the maximum depth and maximum
reinforcement removed. The maximum area of remediation included the combined
effects of repairs to shoulder 13 performed simultaneously with repairs to shoulder 10.
- The inspectors reviewed a sample of field change requests and condition reports
associated with EC 18-0037-02 activities.
- On November 14, 2018, during shoulder 10 repair activities, the licensee inadvertently
sprayed the start-up 02 transformer and two individuals with wet concrete during
clean-up after a successful concrete pour. When concrete was found to be setting up
in the installed hard pipe, the licensee disconnected the hard pipe from the concrete
truck boom and attempted to clear the pipe by pressurizing the high elevation side with
compressed air. This resulted in the concrete in the pipe being ejected at the low
elevation side. Both individuals were assessed by the health center and were
determined to have no injuries. The licensee evaluated the start-up 02 transformer
and determined it to be operable. The licensee entered this issue in to the corrective
action program as condition report 2018-10197. The inspectors questioned the
licensee regarding work management and the use of human performance tools.
Specifically, the inspectors noted a two minute drill required the licensee to identify
what can go wrong and the appropriate actions to prevent those issues. No violations
were identified.
Observation-Selected Issue Follow Up for CR 2018- 71152Annual Sample Review
08424: Unapproved Chemical Consumable into the
Spent Fuel Pool and CR 2018-08340: Foreign
Material Introduced into Spent Fuel Pool
On September 19, 2018, the licensee was performing spent fuel assembly inspections and
identified that a chain attached to a pin on the latching pole used to move the spent fuel
assemblies was hanging straight down. The chain was used to ensure the lock-pin on the
latching pole would not become foreign material in the spent fuel pool (SFP). Upon
inspection, the licensee discovered that a ring used to hold the chain to the pin was missing.
The pins, chain and rings were subsequently secured to the latching pole with tape.
The licensee identified the missing ring on the upper end fitting of a permanently discharged
assembly, and subsequently removed the foreign material from the spent fuel pool. Upon
questioning by the inspectors, the licensee was unable to provide a written evaluation and
determined that the use of tape in the spent fuel pool had not been formally evaluated. Upon
discovering the unapproved condition, the licensee removed the tape from the SFP and
replaced it with approved ty-wraps. Additionally, the licensee generated condition report
2018-08424, Unapproved Chemical Consumable Introduced into the Spent Fuel Pool and
CR 2018-08340: Foreign Material Introduced into Spent Fuel Pool.
Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings,
requires, in part, that activities affecting quality be prescribed by documented procedures of a
type appropriate to the circumstances and be accomplished in accordance with these
procedures. The licensee established Procedure NOP-OP-3001, Chemical Control
Program, Revision 26 as the implementing procedure for controlling chemicals used in or on
structures, systems, or components. Specifically, that procedure was utilized to control
chemicals used in the spent fuel pool activity affecting quality.
Procedure NOP-OP-3061, Step 2.2.6 states, in part, that the use of tapes in or on plant
systems, piping or components, meets the definition of chemical and is required to be
approved per the requirements of this procedure prior to use. Step 4.2 states, in part, that,
the user of the chemical shall review the 3E Company portal per NOBP-OP-3001, Chemical
Control 3E SDS and Permit Process, for the desired product or a currently approved product
suitable for the intended use. On September 19, 2018, the licensee failed to determine
whether the tape was approved for use, as required by the procedure, before using the tape in
the spent fuel pool area.
The inspectors determined that the licensees failure to use an approved material in the spent
fuel pool was contrary to 10 CFR 50, Appendix B Criterion V and was considered a
performance deficiency. The licensees failure to comply with Steps 2.2.6 and 4.2 of
Procedure NOP-OP-3001, Chemical Control Program, constituted a minor violation that is
not subject to enforcement action in accordance with the NRCs Enforcement Policy.
