eVinci Microreactor Breaks Temperature Record
Westinghouse's developing eVinci microreactor reached record temperature levels during zero-power criticality tests conducted in Nevada.
Westinghouse Electric Company announced that the eVinci microreactor achieved a significant milestone during zero-power high-temperature criticality tests conducted in Nevada. During the tests, the reactor reached criticality and completed measurements at a record temperature.
Temperatures Reached During Criticality Tests
In tests conducted by Westinghouse, the eVinci microreactor reached criticality at a temperature of 663 degrees Celsius.
Researchers also performed subcritical reactivity measurements at a record core temperature of 1,011 degrees Celsius.
Center Where the Tests Were Conducted
The experimental studies in question were carried out in partnership with Los Alamos National Laboratory and the Nevada National Security Site.
The tests took place at the National Criticality Experiments Research Center, which is affiliated with the National Nuclear Security Administration of the US Department of Energy.
Data Collection and Model Development Process
The high-quality, temperature-dependent data obtained will be used to strengthen analytical models and accelerate prototype design.
These studies aim to increase understanding of how the reactor design responds when heated to operating conditions accurately.
Executive Statements and Future Goals
Westinghouse President and Chief Executive Officer Dan Sumner stated that this milestone has provided significant momentum to the eVinci program.
Sumner emphasized that teams are rapidly testing and developing advanced nuclear technologies by turning uncertainty into verified evidence.
Technical Specifications of the Microreactor
Featuring a heat pipe-cooled design, the eVinci microreactor is capable of generating up to 5 MWe of power with a 15 MWt core design.
The TRISO-fueled reactor core is designed to operate for eight or more full-power years without refueling.
Shipment and Areas of Use
Manufactured and assembled in a factory, the reactor can be shipped in a container to provide flexible energy for various applications.
This portable and scalable energy solution holds the potential for use in many different fields, including defense and space.
