NRA Grants Permission to Make Changes to Reactor Installation at HTTR under New Regulatory Standards

At a meeting on June 3, the Nuclear Regulation Authority of Japan (NRA) finalized a review report for the High-Temperature Engineering Test Reactor (HTTR), owned by the Japan Atomic Energy Agency (JAEA), saying that it was compatible with the new regulatory standards. The reactor, with a thermal output of 30MW, is situated in Oarai Town, Ibaraki Prefecture. The NRA then issued the Agency its approval to make changes to the reactor installation (basic design approval).

Earlier this year, on March 25, the NRA had issued a draft review report—which was also given to the Japan Atomic Energy Commission (JAEC) and the head of the Ministry of Education, Culture, Sports, Science and Technology (MEXT)—and made it open to the public for comments. It has been five and a half years since JAEA initially filed an application for an examination in November 2014. The HTTR is smaller than light water reactors (LWRs), which typically have electric outputs in the range of 1,000MW, but its outlet temperature of 850℃ to 950℃ at design thermal output—compared with just 300℃ for LWRs—is expected to be used for a broad range of purposes, including hydrogen production, the desalination of seawater, and regional power generation. Moreover, through its use of chemically sta...more
