Program on Technology Innovation:
Area Acoustic and Electromagnetic
Emissions Monitoring—Initial Feasibility
and Proof of Concept
. Product ID:
3002005507. Published July, 2015.
This report contains the results
of an initial feasibility study on the
development of methods and a proof-of-
principle test bed for an integrated system
of acoustic and electromagnetic (AEM)
sensors that can provide non-invasive,
area wide diagnostics of health status
and incipient failure modes for critical
electrical and mechanical systems in
electric power plants.
The early detection of unusual
equipment performance or failures is
critical to the cost-effective operation
and maintenance of electric power
plants. Nevertheless, a comprehensive
monitoring program can be difficult to
implement, costly, and, in some cases,
impractical, when using sensors that are
embedded or placed in direct contact
with the actual systems or equipment to
be monitored. Ambient sensors can be
effective at detecting changes in acoustic
and electromagnetic signatures, which can
be indicative of a degrading condition or
failure, and are typically very competitive
in terms of cost when compared with
similar devices that require installation
on the component or system. Using these
techniques, an electric power plant can
be equipped with area wide monitoring
to identify equipment functionality or
maintenance issues.

BWRVIP-297: BWR Vessel and
Internals Project, Fast Neutron Fluence
and Activation Analysis of Hatch
Unit 1 Shroud Boat Sample
. Product ID:
3002007462. Published February, 2016.
This report documents calculations
of the fast neutron fluence associated with
a boat sample removed from the Hatch
Plant Unit 1 core shroud. Researchers
calculated fast neutron fluence estimates
using the Radiation Analysis Modeling
Application (RAMA) neutron transport
model and compared them to estimates
of fast neutron fluence based on sample
activation measurements. Estimates of
accumulated fast neutron fluence are
important in characterizing the results
of materials testing performed on test
specimens cut from the boat sample.

1. Costs of Decommissioning Nuclear
Power Plants
, March, 2016. NEA#7201.
While refurbishments for the long-
term operation of nuclear power plants
and for the lifetime extension of such
plants have been widely pursued in
recent years, the number of plants to be
decommissioned is nonetheless expected
to increase in future, particularly in
the United States and Europe. It is
thus important to understand the costs
of decommissioning so as to develop
coherent and cost-effective strategies,
realistic cost estimates based on
decommissioning plans from the outset
of operations and mechanisms to ensure
that future decommissioning expenses
can be adequately covered.
This study presents the results of an
Nuclear Energy Agency (NEA) review
of the costs of decommissioning nuclear
power plants and of overall funding
practices adopted across NEA member
countries. The study is based on the results
of this NEA questionnaire, on actual
decommissioning costs or estimates,
and on plans for the establishment and
management of decommissioning funds.
Case studies are included to provide
insight into decommissioning practices
in a number of countries.
2. Five Years after the Fukushima
Daiichi Accident
, February, 2016. NEA#
7284.
Countries around the world continue
to implement safety improvements and
corrective actions based on lessons learnt
from the March 11, 2011 accident at
the Fukushima Daiichi nuclear power
plant. This report provides a high-level
summary and update on these activities,
and outlines further lessons learnt
and challenges identified for future
consideration. It focuses on actions taken
by NEA committees and NEA member
countries, and as such is complementary
to reports produced by other international
organisations.
It is in a spirit of openness and
transparency that NEA member countries
share this information to illustrate that
appropriate actions are being taken
to maintain and enhance the level of
safety at their nuclear facilities. Nuclear
power plants are safer today because of
these actions. High priority follow-on
items identified by NEA committees are
provided to assist countries in continuously
benchmarking and improving their nuclear
safety practices.
