In the never-ending quest
for reliability and safety in the Nuclear Energy electrical
power production industry, testing is an ongoing process.
Nuclear regulatory agencies specify standard acceptable
service lifetimes for components such as pumps, valves,
fittings, piping, etc as a function of their application,
ambient operating conditions, criticality, etc. Maximizing
service lifetimes of these typically very expensive,
nuclear service qualified components can result in
considerable production cost savings from both a component
replacement cost and minimized down-time.
In some applications, service
lifetimes of components can be extended beyond the
standard "worst-case" lifetimes specified by Nuclear
regulatory standards. If operating conditions can
be proven to be less demanding than the worst-case"
conditions used in the development of the standard
lifetime guidelines, a component's service life can
Many components within
a nuclear power generation facility are within areas
that are not safe for human exposure... such as within
the various containment areas. Wiring access to these
containment areas is typically limited and can be
extremely expensive to augment.
With the deployment
of low-power Logic Beach data logging instruments
into these limited access containment areas, operating
conditions can be logged and archived... resulting
in extension of service lifetimes. Logic Beach loggers
have been deployed into low-level containment areas
(dry-wells) during shut-downs then retrieved upon
the next scheduled shut-down for data download, battery
change, and redeployment. Some applications have utilized
serial links for communications, data downloads, and
reprogramming of the logger while in containment.
Logic Beach loggers
are regularly used within the electric power generation
industry for many other types of component life-extension
studies, performance studies, efficiency studies,
and more... . resulting in substantial savings in
energy production costs.
