ASLB sets oral arguments for Long Mott application

By ExchangeMonitor

A Nuclear Regulatory Commission Atomic Safety and Licensing Board will hold oral arguments at 10 a.m. Eastern Time on Oct. 6 on challenges to Long Mott Energy’s construction permit application for a small modular reactor in Seadrift, Texas.

The petitioner, San Antonio Bay Estuarine Waterkeeper (Waterkeeper), was certified for oral argument on Sept. 16 in a memorandum and order by ASLB’s three-judge panel.

The oral argument will allow the ASLB to ask questions to Waterkeeper regarding their petition against Long Mott’s application. The three-judge panel will hear arguments from Waterkeeper, Long Mott Energy and the NRC staff, according to NRC’s Sept. 17 press release.

Waterkeeper filed a petition against Long Mott Energy’s construction permit application on Aug. 11. The local Texas gulf coast group has challenged the SMR application over safety concerns.

Dow and X-Energy filed the application to NRC on March 31 under Dow’s subsidiary company Long Mott Energy.

X-Energy’s project would replace the current energy and steam generation, which is powered by natural gas, with a Xe-100 nuclear plant at Dow’s UCC Seadrift Operations manufacturing site.

The construction permit application is currently being reviewed by the NRC and is anticipated to be completed by November 2026.
