Nuclear Safety Analysis Manager

Job Description

<p><h3>Job Title</h3>
<p>Safety Manager</p>
<p>Location: Oakville, Ontario, Canada</p>
<h3>About the Company</h3>
<p>Terrestrial Energy is developing, for near‑term commercial operation, a zero‑emissions cogeneration plant for the global industry using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative, small and modular design. The IMSR is a Generation IV non‑Light Water Reactor operating at the high temperature required for broad industrial relevance with transformative economic potential. It offers grid‑based electric power generation and industrial cogeneration for many energy‑intensive industries, including petrochemical and chemical synthesis for hydrogen and ammonia production. The IMSR plant achieves almost a 50 percent improvement in efficiency of electric power generation compared to Light Water Reactor plants and supports rapid global decarbonisation of the primary energy system.</p>
