INSPECTION RESULTS
Licensee Identified Non-Cited Violation 71124.06 This violation of very low safety significance was identified by the licensee and has been entered into the licensees corrective action program and is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy.
Violation: Technical Specification 5.5.2 (c), Radioactive Effluent Controls Program, requires monitoring, sampling, and analysis of gaseous effluents.
Contrary to the above, from 1989 to the present, the sample pump flow rates through several isokinetic nozzles was too high to allow for accurate monitoring and representative sampling.
In 1989, automatic flow control features of some effluent monitoring instruments were disabled and in 2016, several new monitors were installed on the same isokinetic nozzle sample lines. Both of these actions prevents accurate monitoring and representative sampling.
Significance/Severity: The inspectors evaluated this finding using IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix D, Public Radiation Safety Significance Determination Process. The inspectors determined that finding was of very low safety significance (Green).
Corrective Action Reference(s): CR-2017-04211 and CR-2018-00283.
Inadequate Procedure Adherence Cornerstone Significance Cross-Cutting Aspect Report Section Initiating Events
Green FIN 05000334/2018001-01 Closed Not Applicable 71153 A self-revealed Green finding was identified when the licensee failed to adequately implement procedure NOP-WM-1001, Order Planning Process. Specifically, FENOC personnel that made a change to work order testing requirements did not receive concurrence from a Unit 1 Senior Reactor Operator nor did they ensure that the original scope and/or intent of the test was met.
Description:
On November 7, 2017, with the plant operating at full power, Unit 1 experienced an automatic turbine trip and coincident reactor trip initiated by a main unit generator fault protection trip. The auxiliary feedwater system automatically actuated on low steam generator water level as expected, and performed as designed. The plant was then stabilized in Mode 3 using the normal main feedwater system.
In response to the Unit 1 reactor trip, FENOC performed a root cause evaluation and identified that the direct technical cause was foreign material within the isolated phase bus ducts, which caused an electrical fault that led to the generator protection trip and subsequent turbine trip and reactor trip. The licensee determined that the pieces of belt found in the B phase bus duct, which were tested and verified to electrically conduct, were large enough to cause sufficient bridging and electrical faults. The licensee also concluded that the foreign material had been in the duct for many years and eventually shifted position due to air flow until it was positioned in a manner that caused the fault. The licensee restored the iso-phase bus on November 12, 2017, by cleaning the duct, removing all foreign material, and performing a satisfactory Hi-Pot test on all three phases. Lastly, the corrective action to preclude repetition was to revise the procedure, 1/2PMP-35-GML/TRF-03E, Iso-Phase Bus Inspection and Test, to clarify the intent and scope to ensure that a full bus inspection is completed as required.
An extent of condition review was also performed and verified that a full bus duct inspection was performed at Unit 2 in 2012 as required by the work scope for a belt guard modification.
The licensee determined that the root cause was decisions individuals made in 2013 that allowed personnel to change work scope without following the process to get approval for the scope change.
In February 2006, a full inspection of the Unit 1 iso-phase bus was performed. All access ports were opened to inspect and clean all bus duct insulators, including internal inspection for foreign material using a borescope. In September 2010, the licensee replaced a drive belt on the duct cooling fan following a fan failure on the B phase fan. No foreign material inspection was performed following the replacement of the belt prior to placing the fan back in service. The licensee identified this as a missed opportunity to investigate potential foreign material intrusion into the duct that could have potentially identified and removed belt foreign material preventing the 2017 Unit 1 trip. In October 2013, the licensee completed a modification to the ducts of the main unit generator that included replacing large portions of the ducts and adding belt guards to the fan belts to prevent further belt failures from introducing foreign material into the ducts. A post work task for this modification was to include complete visual inspections, testing, and cleaning of the iso-phase bus ducts in accordance with 1/2PMP-35-GML/TRF-03E. Based on information the inspectors reviewed in the completed modification work orders from 2013, the crew did not perform the intended borescope inspection and marked the steps for insulator inspection as not applicable. The documented reasoning for the scope change was per satisfactory hi-pot test results and discussion with system engineer. The individual that made a change to work order testing requirements did not receive concurrence from a Unit 1 Senior Reactor Operator nor did they ensure that the original scope and/or intent of the test was met in accordance with the requirements of NOP-WM-1001, Order Planning Process, Revision 20. Therefore, the inspection of the Unit 1 iso-phase bus ducts was not performed as required.
Corrective Action(s): FENOC restored the iso-phase bus on November 12, 2017, by completing the full bus duct inspection, cleaning the duct, removing all foreign material, and performing a satisfactory Hi-Pot test on all three phases. Also, the corrective action to preclude repetition was to revise the procedure, 1/2PMP-35-GML/TRF-03E, to clarify the intent and scope to ensure that full bus inspections are completed as required.
Corrective Action Reference(s): CR-2017-11134
Performance Assessment:
Performance Deficiency: FENOC procedure NOP-WM-1001, Order Planning Process requires that individuals making changes to testing requirements shall receive concurrence from a Senior Reactor Operator and ensure that the original scope and/or intent of the test is met. On October 31, 2013, individuals changed the scope of work order testing requirements to inspect the iso-phase bus ducts, but did not receive concurrence from the Unit 1 Senior Reactor Operator nor did they ensure that the original scope and/or intent of the test was met.
Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the human performance attribute of the Initiating Events cornerstone and affected the cornerstones objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.
Significance: The inspectors assessed the significance of the finding using IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix A, Exhibit 1, Initiating Events Screening Questions. The inspectors determined that this performance deficiency did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. Therefore, the inspectors determined the finding to be of very low safety significance (Green).
Cross-Cutting Aspect: No cross cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On April 3, 2018, the inspectors presented the quarterly resident inspector inspection results to Mr. Richard Bologna, Site Vice President, and other members of the Beaver Valley Power Stations staff.

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.

INSPECTION RESULTS
Licensee Identified Non-Cited Violation
This violation of very low safety significance was identified by the licensee and has been
entered into the licensees corrective action program and is being treated as a Non-Cited
Violation, consistent with Section 2.3.2 of the Enforcement Policy.
Violation: Technical Specification 5.5.2 (c), Radioactive Effluent Controls Program, requires
monitoring, sampling, and analysis of gaseous effluents.
Contrary to the above, from 1989 to the present, the sample pump flow rates through several
isokinetic nozzles was too high to allow for accurate monitoring and representative sampling.
In 1989, automatic flow control features of some effluent monitoring instruments were
disabled and in 2016, several new monitors were installed on the same isokinetic nozzle
sample lines. Both of these actions prevents accurate monitoring and representative
sampling.
Significance/Severity: The inspectors evaluated this finding using IMC 0609.04,
Initial Characterization of Findings, and IMC 0609, Appendix D, Public Radiation Safety
Significance Determination Process. The inspectors determined that finding was of very low
safety significance (Green).

Green
Closed
Not Applicable
A self-revealed Green finding was identified when the licensee failed to adequately implement
procedure NOP-WM-1001, Order Planning Process. Specifically, FENOC personnel that
made a change to work order testing requirements did not receive concurrence from a Unit 1
Senior Reactor Operator nor did they ensure that the original scope and/or intent of the test
was met.
Description: On November 7, 2017, with the plant operating at full power, Unit 1 experienced
an automatic turbine trip and coincident reactor trip initiated by a main unit generator fault
protection trip. The auxiliary feedwater system automatically actuated on low steam
generator water level as expected, and performed as designed. The plant was then stabilized
in Mode 3 using the normal main feedwater system.
In response to the Unit 1 reactor trip, FENOC performed a root cause evaluation and
identified that the direct technical cause was foreign material within the isolated phase bus
ducts, which caused an electrical fault that led to the generator protection trip and subsequent
turbine trip and reactor trip. The licensee determined that the pieces of belt found in the B
phase bus duct, which were tested and verified to electrically conduct, were large enough to
cause sufficient bridging and electrical faults. The licensee also concluded that the foreign
material had been in the duct for many years and eventually shifted position due to air flow
until it was positioned in a manner that caused the fault. The licensee restored the iso-phase
bus on November 12, 2017, by cleaning the duct, removing all foreign material, and
performing a satisfactory Hi-Pot test on all three phases. Lastly, the corrective action to
preclude repetition was to revise the procedure, 1/2PMP-35-GML/TRF-03E, Iso-Phase Bus
Inspection and Test, to clarify the intent and scope to ensure that a full bus inspection is
completed as required.
An extent of condition review was also performed and verified that a full bus duct inspection
was performed at Unit 2 in 2012 as required by the work scope for a belt guard modification.
The licensee determined that the root cause was decisions individuals made in 2013 that
allowed personnel to change work scope without following the process to get approval for the
scope change.
In February 2006, a full inspection of the Unit 1 iso-phase bus was performed. All access
ports were opened to inspect and clean all bus duct insulators, including internal inspection
for foreign material using a borescope. In September 2010, the licensee replaced a drive belt
on the duct cooling fan following a fan failure on the B phase fan. No foreign material
inspection was performed following the replacement of the belt prior to placing the fan back in
service. The licensee identified this as a missed opportunity to investigate potential foreign
material intrusion into the duct that could have potentially identified and removed belt foreign
material preventing the 2017 Unit 1 trip. In October 2013, the licensee completed a
modification to the ducts of the main unit generator that included replacing large portions of
the ducts and adding belt guards to the fan belts to prevent further belt failures from
introducing foreign material into the ducts. A post work task for this modification was to
include complete visual inspections, testing, and cleaning of the iso-phase bus ducts in
accordance with 1/2PMP-35-GML/TRF-03E. Based on information the inspectors reviewed in
the completed modification work orders from 2013, the crew did not perform the intended
borescope inspection and marked the steps for insulator inspection as not applicable. The
documented reasoning for the scope change was per satisfactory hi-pot test results and
discussion with system engineer. The individual that made a change to work order testing
requirements did not receive concurrence from a Unit 1 Senior Reactor Operator nor did they
ensure that the original scope and/or intent of the test was met in accordance with the
requirements of NOP-WM-1001, Order Planning Process, Revision 20. Therefore, the
inspection of the Unit 1 iso-phase bus ducts was not performed as required.
Corrective Action(s): FENOC restored the iso-phase bus on November 12, 2017, by
completing the full bus duct inspection, cleaning the duct, removing all foreign material, and
performing a satisfactory Hi-Pot test on all three phases. Also, the corrective action to
preclude repetition was to revise the procedure, 1/2PMP-35-GML/TRF-03E, to clarify the
intent and scope to ensure that full bus inspections are completed as required.
Corrective Action Reference(s): CR-2017-11134
Performance Assessment:
Performance Deficiency: FENOC procedure NOP-WM-1001, Order Planning Process
requires that individuals making changes to testing requirements shall receive concurrence
from a Senior Reactor Operator and ensure that the original scope and/or intent of the test is
met. On October 31, 2013, individuals changed the scope of work order testing requirements
to inspect the iso-phase bus ducts, but did not receive concurrence from the Unit 1 Senior
Reactor Operator nor did they ensure that the original scope and/or intent of the test was met.
Screening: The inspectors determined the performance deficiency was more than minor
because it adversely affected the human performance attribute of the Initiating Events
cornerstone and affected the cornerstones objective to limit the likelihood of events that upset
plant stability and challenge critical safety functions during shutdown as well as power
operations.
Significance: The inspectors assessed the significance of the finding using IMC 0609.04,
Initial Characterization of Findings, and IMC 0609, Appendix A, Exhibit 1, Initiating Events
Screening Questions. The inspectors determined that this performance deficiency did not
cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant
from the onset of the trip to a stable shutdown condition. Therefore, the inspectors determined
the finding to be of very low safety significance (Green).
Cross-Cutting Aspect: No cross cutting aspect was assigned to this finding because the
inspectors determined the finding did not reflect present licensee performance.
Enforcement: Inspectors did not identify a violation of regulatory requirements associated with
this finding.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On April 3, 2018, the inspectors presented the quarterly resident inspector inspection results
to Mr. Richard Bologna, Site Vice President, and other members of the Beaver Valley Power
Stations staff.
