Applications
- A Training Simulator
For operators and engineers training in reactor theory, transient
phenomena, and diagnostic skills. A comprehensive training lesson
plan from basic principles to symptom-oriented emergency diagnosis
can be developed in conjunction with the software.
- Generate emergency drill scenarios and conduct actual exercises.
Data at a selected time interval can be prepared and handed out
to drill teams for an undisclosed event. Data on core damage,
radiological release, and offsite dose projection support comprehensive
exercises.
- Parametric/Scoping Study
For system modifications and licensing support, development of
emergency procedures, responding to regulatory inquiries about system performance, equipment sizing, operator actions, etc.,
repetitive runs can be conducted with immediate turnaround for
answering "what if" questions.
- Probabilistic Risk Assessment (PRA)
To predict consequences of selected event branches leading to
core melt and/or containment failure and their contributions
to overall plant risk. Application in Individual Plant Examination
(IPE) front-end prediction of core uncovery.
Technical Information
Hardware & Software Requirements
Minimum system requirements are a Pentium or any compatible
processor and SVGA graphics. The operating system should be at
least Windows 95 or NT 4.0 with MS Office Suite installed.
Simulation speed is adjustable from real-time to faster than
real-time, dependent on processor speed. For a 500 MHz processor,
the maximum speed is about 16 times faster than real-time.
Services provided by MST
Installation and on-site training can be arranged, if necessary.
Maintenance and technical support are provided free of charge
for the first year upon delivery. Extended technical service
is available upon request.
Free Downloads
These downloads are not play-back-only demos but actually functional software that can conduct extensive simulations with interactive control.
The primary display mimics the nuclear steam supply
system (NSSS) and the containment system of a PWR with two or
more inverted U-bend steam generator loops. The generic model
can be modified to be "plant specific" for any Westinghouse,
C-E, Framatome, or KWU design. A plant specific version may either
use the lumped loop model or each loop be modelled individually.
The display also represents the controllable system as small
panels with the important equipment shown as icons (i.e., pumps,
valves, heat exchangers). Control rod position and motion are
displayed by the motion of simulated control rods. If there is a
break in the NSSS, it will be shown dynamically at the break
location with the flow rate digitally displayed.
On the right-hand side panels of the mimic, there are control
panels for the reactor, steam generators and turbine, pressurizer,
etc. Panels for the High Pressure Injection System, Accumulators,
Residual Heat Removal System (RHR), Reactor Building Spray, Vent,
and Fan Coolers are at the left side. At the bottom of the mimic,
there are panels for Reactor Protection System (RPS), Safety
Feature Actuation System (SFAS), and P-T diagram showing the primary
coolant's saturation margin.
