43© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Focus Areas and Key Take-A-Ways
Condition Based Maintenance
Integration of online monitoring into M&D
centers is reducing PM costs
– Reduces manual data collection and allows
more time for analysis and troubleshooting
using APR tools.
New condition monitoring tools and emerging
technology are allowing more efficient use of
staff time
– Ex. Use of on-line 360 degree IR for switchyard
monitoring and use of acoustics in conjunction
with an optical camera to detect equipment
anomalies.
Hoisting Rigging and Crane
Ensuring crane is stabile and proper rigging is used.
– Disturbing number of incidents recently identified where either the crane tipped or the rigging failed to secure the load due to inadequate supervision of on-site contractors.
The lack of uniform training standards and testing plus overly burdened processes increase the cost of rigging and lifting activities. – Committed to supporting “Delivering the Nuclear
Promise, the HRCUG seeks to assemble an advisory group of members, vendors, NEIL, and INPO to find ways to streamline processes and reduce costs while actually increasing safety.

Focus Areas and Key Take-A-Ways
Preventive Maintenance Basis Database Japan RCM-CBM
Key development and implementation group
for implementation of Condition Based vs.
Time Based Maintenance process.
Implementing continuous improvement in the
Predictive Maintenance process and interface
with international peers and exchange of best
practices
Next meeting on September 21, 2016, in
conjunction with the ERWG and PMWG
meetings in Charlotte. Attendees will learn
how to better use and apply this web-based
tool and review work planned on improving
the tool over the next 5 years.
With the PMBD Project moving into base
funding in 2017, the PMBDUG will be
replaced in following years by Technical
Advisory Group (TAG) Meetings as
needed based on PMBD project efforts.

Focus Areas and Key Take-A-Ways
Large Electric Motor
Workshop Topics that address recent industry
events such as Field Cable and Motor
Testing and Termination Issues which led to
EPRI project to evaluate the application of
Very Low Frequency Testing to Electric
Motors
Developed criteria for evaluation of in-
process inspection of motor windings, EPRI
3002003261, Sample Coil Inspection Guide.
This document has drawn the attention of the
IEEE Dielectric Committee for possible
collaboration.
Maintenance Rule
Provide information exchange between
utilities and EPRI to resolve technical issues
from the baseline inspections and the
ongoing revisions to the rule.
Develop technical guides and documentation
of good practices that can reduce costs of
implementation, increase consistency among
utilities, leverage rule activities to improve
plant performance, or reduce vulnerability to
regulatory compliance issues.

Integrated Life Cycle Management
(ILCM) – Update

What is ILCM Address asset management decisions for long term operations.
Integrated Life Cycle Management (ILCM) combines asset failure
likelihood with economic impact to quantify the financial risks of operating
plants (IPOP module).
This combination offers the possibility of defining an optimum long-term
operating and financial strategy that reduces plant operating risks and
improves financial performance.
70© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
What is ILCM
The ILCM software links scientifically developed component and structure
degradation algorithms with plant-specific financials to enable better-
informed decisions about the control of capital spending.
The software platform provides a consistent basis for making decisions
about multiple major plant components and making decisions across
multiple plants.
71© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
ILCM Components
Limited to high cost and high consequence assets for Life Extension Evaluations.
Plant specific algorithms based on:– Dominant material aging characteristics
– Modified by plant operating stressors
– Modified by maintenance stressors
Components– Turbine, Generator, large pumps, condensers, transformers
feed water heater, steam generator, pressurizer
Structures– Spent fuel pool, containment, torus
72© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
The ILCM program utilizes a Likelihood of Failure (LoF) curve to calculate
an optimum replacement time.
The original LoF curves were developed using “Physics of Failure”
methods.
It is desirable to simplify the calculation of the LoF curve to calculate the
likelihood that a component will have to be replaced either for failure or for
other reasons like obsolescence.
The likelihood of replacement for failure and/or obsolescence is referred to
as Likelihood of Replacement (LoR).
This is expected to greatly increase the usability of ILCM to any
component or system that a utility is evaluating.
ILCM – LoF vs LoR
73© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Likelihood of Replacement (LoR)
“Expert elicitation” methods are used to develop an LoR curve.
Expert elicitation can be used by plant personnel on any
component or structure whether or not it is already explicitly
included in ILCM.
Methodology allows input from one or several “experts”.
An LOR curve will be used in ILCM.
The rest of the ILCM calculations can proceed normally.
74© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
The LoR Methodology Approach
• Identify Component
• Identify Background Information
Scope
• Industry and plant performance
• EOL guidance
OE • Expert Elicitation
• Likelihood
• Variability
• Timing
• Comparative Ranking
Probabilistic
Evaluation
• LoR curve
Results
75© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
An Excel workbook is provided to those being elicited.
It is expected to require approximately 30 minutes to fill out the
workbook.
The workbook from each person elicited is sent to an Elicitation
Coordinator.
Another Excel workbook is used by the Elicitation Coordinator to
combine the responses and to provide an LoR curve – the
likelihood of replacement being required versus time.
This has been piloted with Duke and Exelon.
Updates to the workbooks are being performed based on
feedback from the pilots.
LoR Process
76© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Identify a component or system and categorize it into one of
the following groups:
– I&C
– Structural
– Active Mechanical
– Passive Mechanical
– Active Electrical
– Passive Electrical
LoR Process
77© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Elicit input from one or several personnel that are familiar with the
system.
Identify component or system.
Identify failure mechanisms and stressors.
Identify previous failures that have occurred.
Will the degradation/obsolescence be recognized well before a
failure will occur in the field?
Identify whether replacement is controlled by likelihood of failure or
obsolescence (or both)
Process

Heat Exchanger Module
The ILCM software Version 2.1 contains a feedwater heater module to
estimate the Likelihood of Replacement (LOR) of feedwater heaters in
nuclear power plants.
The feedwater heat exchanger module has been expanded to include
many more heat exchangers, including CCW, RHR, Turbine Oil,
Diesel Jacket Water, Fuel Pool Cooling, Containment Fan Coolers,
and others.
The fluid conditions will be expanded to include:
o Sea Water
o Brackish Water
o Open Cycle Fresh Water
o Closed Cycle Fresh Water
o Oil
o Air
o Closed Cooling Water
o Primary Water

Heat Exchanger Degradation Mechanisms Considered
Degradation mechanisms considered for the shell include:
– Flow Accelerated Corrosion (FAC)
– Microbiologic Influenced Corrosion (MIC)
Degradation mechanisms considered for the tubes include:
– Microbiologic Influenced Corrosion (MIC)
– Erosion
– Stress Corrosion Cracking (SCC)
– Wear (vibration, fretting, etc.)
Degradation mechanisms considered for the internals (baffle plates,
tie rods, etc.) include:
– Steam damage
81© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Potential Capabilities of ILCM – PM Decisions
ILCM currently evaluates long-term replace/refurbish decisions
based on likelihood of failure, consequences, and cost.
This can be extended to short-term decisions on PMs.
An evaluation of the following items will allow input to a PM
decision to be made:
– The likelihood of failure change for a longer PM frequency
– The consequences/undesirability of a failure during operation
– The cost is maintenance time, cost of plant operation time if a
downpower is required, and availability of parts
Such an evaluation may be possible with collaboration between
the PMDB and ILCM.
82© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Potential Capabilities of ILCM – Other Applications
Many ILCM likelihood of failure curves are developed using
“physics of failure” techniques.
This method creates algorithms that are based on the
physics of how the degradation occurs and effects the
material capability.
These methods can be extended to other degradation
issues, like baffle bolt cracking, and other MRP and
BWRVIP issues.
Degradation algorithms can be inserted into ILCM to provide
insight for repair/replace decisions.
83© 2016 Electric Power Research Institute, Inc. All rights reserved.© 2015 Electric Power Research Institute, Inc. All rights reserved.
Potential Capabilities of ILCM – LTAM/LCMP Integration
ILCM currently provides stand-alone input to
replace/refurbish decisions on components.
Many utilities are using similar Life Cycle Management Plan
(LCMP) and Long Term Aging Management (LTAM)
formats.
ILCM can be adapted to provide easily-integrated output in a
LCMP or LTAM program.
This could reduce the work required to develop and update
long term plans.

A fault on an offsite transmission
line resulted in an undervoltage
(approximately 11% drop)
condition at the plant, causing all
four safety busses to isolate due
to degraded grid relay actuation
and both units to trip. Offsite
power was not available to the
buses due to the undervoltage
condition. The faulted line was
isolated from the plant and offsite
power was available in about 47
seconds, though not restored
until 20 minutes later.

– Though no Category I events from weather in 2015, there was a
significant Category II event due to a winter storm; weather remains
#1 cause of LOOP events over 10 year rolling average.
– Human performance issues at the plant contribute to many “near
misses”, i.e. Category II, IVa events.
– Failures of Large Power Transformers (LPTs) contributing to
Category II events.
