TECHNOLOGY
Most Advanced Technology
CORYS’ products are widely regarded as state of the art in the nuclear simulation industry.
CORYS technology is state-of-the-art allowing real time dynamic simulation. This same technology is used for engineering tools and full scope simulators optimising investments for our customers.
ALICES
Integrated simulation toolset
ALICES is an integrated simulation toolset designed for the development, maintenance and operation of major simulator projects requiring extensive engineering resources working in parallel, sometimes even from different geographical sites.
ALICES is characterised by several innovative features which improve productivity at each stage of simulator development:
-
Easy development of real-life objects, stored in dynamic libraries
-
Fast and efficient plant model development and update
-
Automatic interfacing between the different simulator modules
-
Standardized tools to interface with third-party code and software
-
State-of-the-art Instructor Station
-
Fully graphical simulator executive
-
Data tracking and consistency management
DRAC
Advanced thermal-hydraulic model
DRAC is a fully 5-equation model specifically developed for the modelling of two-phase flow phenomena in light water reactors and covering all the specific phenomena relevant to different PWR accident situations and scenarios (critical two-phase flow, burn-up, reflooding, different flow regimes, two-phase natural circulation, reflux boiling, etc.).
DRAC interfaces seamlessly with ALICES
DRAC has been successfully implemented and used in numerous simulators developed by CORYS. It is validated against best estimate safety analysis codes including RELAP 5 and CATHARE. DRAC was also chosen as the reference thermal hydraulic code in the severe accident code ASTEC, jointly developed by IRSN (France) and GRS (Germany).
The use of DRAC for containment model has also been validated against reference calculations based on PAREO (point model containment code for P&T calculations developed and qualified by EDF).
T-REX
Real-time executive and Instructor Station
CORYS T-REX simulator executive, instructor station and toolkit enable a modern feature-rich simulation environment. Our T-Rex simulation platform is the most widely used in the US nuclear industry.
T-REX provides capabilities and ease of use never before seen in the simulator industry and consists of a real-time simulator executive and toolkit, a complete, full-featured instructor station and a sophisticated graphical development environment.
The T-REX instructor station offers a complete set of instructor station applications which are designed for ease of use. Earlier instructor stations required a significant level of expertise to run the simulator during training scenarios and to develop lesson plans. Instructors were required to memorize or look up and type in cryptic database labels or expert commands. The T-REX instructor station uses modern Windows capabilities like drag-and-drop to make this unnecessary.
Instructors are able to operate the simulator with minimal simulator-specific knowledge.
CORYS provides ongoing support and updates for ensuring a long term life cycle to the T-Rex product.

THOR
Advanced two-phase flow modelling
Since being introduced in 1996, the THOR advanced thermal hydraulic and neutronics models have been installed on more simulators than all other advanced models combined.

by Nuclear Industry
As a result, THOR models are the most thoroughly tested and benchmarked models in the industry. THOR has modeled reactor coolant systems, reactor cores, and steam supply systems for numerous PWR’s and BWR’s.
In 2001 the first THOR-BOP models were installed on the Dominion Surry nuclear plant simulator, for the first time extending the high fidelity of a true two-phase, five-equation, non-equilibrium numerical solution throughout the secondary plant system models. Since then, numerous simulators have contracted to install THOR-BOP.
As computer processing power continued to increase, it has become possible to extend the THOR models into other areas, including the containment, HVAC and radiation transport model. THOR is used to model any fluid system, be it liquid, gas or two-phase
Interface seamlessly with full scope simulator
The CORYS CAN I/O system provides the ultimate in flexibility. 16 bit precision ensures accuracy.
I/O systems
Setup and replacement is a simple plug-in with external micro switches to set the CAN network address and transmission rate.
The CORYS I/O system modules are based upon standard hardware components and are fully compliant with ISO-11898 for High Speed CAN. Status lights are provided to signal defective wiring and network communication problems.
-
Easy to use utilities for CAN I/O system configuration, monitoring and diagnostics are supplied.
CORYS CAN I/O system is characterized by high throughput, rapid scanning rates and good reliability. Standards-based design and a very large number of installations on nuclear plant and train simulators ensure long term maintenance and support.
