X-energy, Dow apply to build an advanced reactor project in Texas
Dow and X-energy announced today that they have submitted a construction permit application to the Nuclear Regulatory Commission for a proposed advanced nuclear project in Seadrift, Texas. The project could begin construction later this decade, but only if Dow confirms “the ability to deliver the project while achieving its financial return targets.”

It has been proposed to build an accelerator for the production of tritium. A transient natural convection model of the accelerator blanket primary heat removal (HR) system was developed to demonstrate that the blanket could be cooled for a sufficient period of time for long-term cooling to be established following a loss-of-flow accident (LOFA). The particular case of interest in this work is a complete LOFA. For the accident scenario in which pumps are lost in both the target and blanket HR systems, natural convection provides effective cooling of the blanket for ∼68 h, and if only the blanket HR systems are involved, natural convection is effective for ∼210 h. The heat sink for both of these accident scenarios is the assumed stagnant fluid and metal on the secondary sides of the heat exchangers.
