Sartrex Inc products

Sartrex Power Control Systems specializes in integrating Programmable Logic Controllers (PLCs) into complex systems for Process Automation and Instrumentation. The company has an expert team of software engineers, electronic engineers and mechanical engineers who can design systems requiring the utmost in complexity and reliability. These engineers are capable of designing systems from the ground up, providing turnkey products for your needs. Many of the systems provided include industrial control computers and network switches. Most systems are housed in seismically qualified cabinets will survive the most rigorous operation environments.

The CANDU Safety Shutdown System consists of two separate systems designed to shutdown a CANDU reactor during an emergency. Its reliability is critical for the safety of the public. The system consists of highly reliable instrumentation cabinets incorporating:

The Advanced Digital Control Centre represents a giant leap forward in the control of power generation facilities. Sartrex, in partnership with AECL, designed this complex system and currently manufactures and markets it worldwide.

The Sartrex Failed Fuel Location System (FFLS) identifies a failed fuel channel in a nuclear reactor. It senses neutron decay in the heat transport water {heavy water) leaving the reactor core. During the nominal fission process, the fuel rods retain nuclear fuel, If radioactivity escapes from the rods into the surrounding water, the FFLS will detect the high levels of delayed neutron activity.

The Sartrex Model 209L is one of the world’s premiere Tritium-In-Air monitors. Users worldwide appreciate its functionality, portability and reliability. The rugged aluminum housing ensures reliable operation in the most demanding of environments. The clear digital readout allows the operator to take error-free readings at a glance.

The Model 309B (LD) Portable Tritium-In-Air monitor adds a new dimension to the versatility of monitoring instrumentation for the Nuclear Industry. The only true dual purpose instrument in the industry, Model 309B (LD) enables you to use the monitor as both a continuous remote area monitor and as a hand-held unit ensuring absolute flexibility.

The Dockside Radiation Monitoring System is a custom designed radiation detection system that is positioned beside visiting Nuclear Powered Vessels (NPVs) to measure gamma radiation. A Base Station and up to 3 Remote Monitors inland continuously monitor any gamma radiation emanating from the NPV If radiation from the NPV increases beyond a preset level, the system goes into alarm mode and initiates the Nuclear Emergency Response process.

Auto Load and Unload Machines are being used by Health Canada to record the amount of radiation, a person working within the parameters of radioactive equipment, has contracted over a period of time. Each holder, which is identified by name and number, has a TLD card insert which absorbs the radiation. Both the machines have a rotary indexing system where six workstations are positioned around a circular table to:

The Sartrex Poison Tank Ball Position Detector uses a photoconductive cell detection system to monitor the level of fluid in liquid poison tanks of the Liquid Injection Shutdown System. The tanks contain high purity, oxygen tree heavy water that is light straw in colour. Two light emitting diodes are screwed into the sides of the tanks, directly opposite each other. Normally a polyethylene ball, floating on the fluid, blocks the optical link between the two units. If the ball drops low enough, the photo-transistor in unit two sees the radiant output from unit one and triggers the alarm. A power failure can also trigger the alarm condition.

The Sartrex Reactor Trip Switch is one of the most critical elements in the CANDU Main Control Room system. It provides for a manual shutdown for the reactor in a controlled fashion. The operator may shut down one of each of the channels at a time or select the ‘Trip’ function to shut down all channels at once. The majority of the trip functions are automatic being generated by the safety shutdown system and this switch is the main means of a manual trip or shutdown.
