BIoGEORGE
Microbiologically influenced corrosion
(MIC) is an ever-present threat to nuclear plant service water
systems, particularly standby and redundant systems – some
safety-related – in wet layup for extended periods of time.
Fortunately, SI’s on-line, real-time BIoGEORGE monitoring
system can provide early warning of biofilms before these
rapidly forming films can get a toe-hold. BIoGEORGE also provides
a reliable indication of the effectiveness of biocide treatments,
plus feedback on biocide treatment selection, timing, and
concentrations. BIoGEORGE is available from SI under EPRI
license.

SIcams2
 The
SI Component Assessment Management System
(SIcams2) is a powerful PC compatible database
program that organizes and displays inspection and repair data
for all types of power stations. General reports and commonly
used forms can easily be created using one mouse click. Quick
access to critical action items during outage planning is just
as easy. The system's inherent flexibility allows it to be customized
to the user's specific reporting and query requirements. |
Creep-FatiguePro
 Creep-FatiguePro
is an automated life consumption monitoring system for fossil
plant equipment developed by EPRI
and SI. Plants exhibiting aging characteristics or approaching an age where service-related damage would be expected to commence, and those plants operating (or contemplating) cyclic operation are excellent candidates for Creep-FatiguePro and can expect
to derive direct cost benefits through its utilization. |
FatiguePro
Metal fatigue from cyclic stresses can shorten the life of critical
nuclear plant components, but FatiguePro, a real-time fatigue
monitoring software system developed by SI and licensed by EPRI,
automatically tracks fatigue usage and transients in these key
components, using existing plant instrumentation. FatiguePro
facilitates plant life extension/license activities by providing
an immediate, up-to-date and continual assessment of fatigue
usage in all critical vessels and piping. As a result, this
Windows-based software is used in more nuclear plants worldwide
than any comparable system.

LIFECODE
 Accurately
measure critical tube dimensions and predict the remaining life
of individual tubes with LIFECODE. SI
measures tube wall and internal oxide scale thickness to predict
remaining tube life using the LIFECODE software.
Field measurements are achieved by use of focused array UT technology and TestPro™,
a PC-based digital UT system. |
LPRimLife
 Perform
life assessment of cracked steam turbine rotors with LPRimLife.
Stress corrosion cracking (SCC) in the blade attachment region
of LP turbine rotors is the most significant problem affecting
steam turbines today. This code, which was developed for EPRI
by SI, combines the necessary stress analysis and fracture mechanics
algorithms with applicable material degradation data to provide
an easy-to-use tool to estimate the remaining life of LP rotors
with rim-attachment cracking. |
pc-CRACK
Sophisticated fracture mechanics analyses – whether linear-elastic,
elastic-plastic, or creep – are performed quickly and easily
with SI-developed pc-CRACK. The Windows-based software analyzes
and predicts flaw behavior, including calculation of crack growth
rates and critical crack sizes for pressure vessels, piping,
steam turbines, and structures, with immediate graphics display
of analysis results. pc-CRACK applications include ASME Code
Section XI flaw evaluations as well as weld overlay design.

VSI-VersaDAS,
SI-MiniDAS, and TTVMS
A reliable track record of vibration data is needed before any
nuclear plant piping vibration issues can be resolved. SI offers
a line of data acquisition systems that collect and analyze
vibration data, including portable SI-MiniDAS; high-speed, automated
SI-VersaDAS; and real-time TTVMS (Transient Torsional Vibration
Monitoring System), with both automated and manual acquisition
capabilities. SI’s proprietary systems, either desktop- or laptop-based,
are suitable for problems involving small-bore piping, socket
welds, main steam piping, turbine-generator rotors, and other
vibration-prone components.

WinPRAISE
Probabilistic fracture mechanics analyses of nuclear reactor
vessels and piping can be expedited with WinPRAISE, originally
developed for the NRC. The latest version of the software
can analyze crack initiation and growth caused by fatigue,
primary water stress corrosion, intergranular stress corrosion,
and flow-accelerated corrosion. Windows-based WinPRAISE can
analyze multiple failure modes, including leaks, large leaks,
and LOCAs, in a single computer run.
