BWRVIP-41, Revision 4: BWR Vessel
and Internals Project, BWR Jet Pump
Assembly Inspection and FlawEvaluation
Guidelines
. Product ID: 300203093.
Published July 2014.
The Boiling Water Reactor Vessel
and Internals Project (BWRVIP), formed
in June 1994, is an association of utilities
focused exclusively on BWR vessel
and internals issues. This BWRVIP
report provides information on potential
failure locations in BWR/3–6 jet pump
components and recommends an
inspection program designed to ensure
that the integrity of all jet pump safety
functions is maintained. This Revision
of BWRVIP-41 (Revision 4) is based
on the previously published Revision 3
and incorporates the results of BWRVIP
inspection optimization as documented in
BWRVIP-266: BWRVessel and Internals
Project, Technical Bases for Revision of
the BWRVIP-41 Jet Pump Inspection
Program.

Materials Reliability Program:
Investigation of Likely Local Primary
Circuit Chemistries in PWR Plants (MRP-
387)
. Product ID: 3002002987. Published
July 2014.
Reviews of stress corrosion cracking
(SCC) events of austenitic stainless
steel components in the primary system
of pressurized water reactors (PWRs)
have shown that they typically occur
in occluded or low-flow regions (dead
legs). Such regions are prone to local
concentration of contaminants such as
oxygen and chlorides that contribute
to SCC. These regions are relatively
inaccessible and do not lend themselves to
monitoring of local chemistries there. As
a result, there is limited knowledge about
the actual conditions in such locations.
This knowledge gap has been identified
in the Electric Power Research Institute
(EPRI) Materials Management Matrix
Project Gap and Opportunity Assessment
as a medium-high priority and is of
interest to EPRI’s Advanced Technology
(ANT) Program. Information from
closing this gap is also needed to address
a high-priority Materials Reliability
Program (MRP) issue management table
(IMT) gap on the SCC of stainless steels
exposed to primary water. Accordingly,
the work reported here was undertaken to
improve understanding of the chemistry
in primary-side dead legs or low-flow
regions. This report presents the findings
of a modeling effort to simulate those
conditions.

Summer 2014
. Product ID: 3002004230.
Published July 2014.
The Maintenance Rule Users
Group
Update
(MRUG)
Update
newsletter communicates issues and
information important to Maintenance
Rule Coordinators and those involved in
supporting Maintenance Rule programs.
Articles are provided by MRUG
members, industry experts, regulators,
and EPRI personnel. The MRUG
Update is published twice a year and is
available to all EPRI-member utilities,
not just MRUG members. It encourages
communication among all Maintenance
Rule personnel.

Loss of Offsite Power at U.S. Nuclear
Power Plants: Summary of Experience
Through 2013
. Product ID: 3002003115.
Published July 2014.
This report describes loss of offsite
power events that occurred during 2013
at nuclear power plants operating in the
United States and offers insights into
the causes of such events for the 10-year
period 2004–2013.

Maintenance Rule Implementation
Self-Assessment Guidelines for Nuclear
Power Plants
. Product ID: 3002002867.
Published July 2014.
The information contained in
this guideline represents a collection
of industry knowledge that describes
programmatic and process attributes,
including techniques and good practices,
to assist in the self-assessment of
Maintenance Rule (MR) programs to
determine their effectiveness in meeting
the requirements of 10CFR50.65,
Maintenance Rule
.

Nuclear Maintenance Applications
Center: Maintenance and Modification
Work Planner Training Program
Description
. Product ID: 3002002821.
Published August 2014.
The purpose of this report is to
provide guidance for the development of
a training program for the qualification
of maintenance and modification work
planners. The training program is intended
to provide them with the fundamental
knowledge and skills required to prepare
consistent, high-quality packages aligned
with site-specific and industry standards.
This report provides a standard
approach
for
developing
and
implementing a work planner training
program to facilitate the consistent
and controlled transfer of important
knowledge and skills to trainees enrolled
in the program.

Azimuthal Power Distribution on BWR
Fuel
. Product ID: 3002002910. Published
August 2014.
This report describes the calculations
of detailed azimuthal power profiles
in nuclear fuel rods. The neutronics
method used to determine the power
profiles is the TRANSLAT lattice
physics code, which is an advanced
deterministic transport methodology
featuring arbitrary geometry modeling,
enhanced spatial variation resonance
treatments, neutron and gamma particle
transport, and detailed energy deposition
and time-average depletion methods. The
azimuthal power profiles calculated by
TRANSLAT are generated in a form to
facilitate their use in CORAL.
