BTA for the Jules Horowitz Reactor

Wozair Limited have been selected to manufacture Blast Protection Dampers for the Jules Horowitz Reactor (RJH) which is currently under construction at Cadarache in Southern France. The RJH is a Material Test Reactor (MTR) named after the 20th century French nuclear scientist Jules Horowitz and is expected to begin operation in 2021.

The reactors construction was recommended by ESFRI as a replacement for the European Union’s existing materials testing reactors, which were all built in the 1960’s, and are expected to reach the end of their service lives by 2020.

Blast Tube Array (BTA) will be provided for the programme in both single and modular sizes of up to 2440W/1300H and 2500W/1000H. The dampers are located on the MVK and MVL backup networks between the external AHU and between the exhaust fans and external fans. Blast systems will also be included on the fresh air ducting and exhaust of cooling units EIS2.

The Wozair BTA is a technical revolution in blast protection, addressing several technical challenges whilst providing improved safety and protection.

Years of research and development have resulted in an elegant philosophy to wave attenuation that breaks down the blast overpressure in a static device. The result is a lower pressure drop, no moving parts and maintenance free operational lifetime in an extremely cost-efficient product.

Wozair Limited will be providing full documentation in dual-language for the project to meet French standards with definition and follow up folders for quality, traceability and workers qualifications. Documentation for the qualification of the BTA under the project conditions will also be provided.

Wozair are thrilled to be a part of the project which is the largest new platform for irradiation experiments in support of Generation II and III reactors, Generation IV technologies, and radioisotope production.
