Molten Salt Reactor Vessels
Roben, Mfg, Inc. manufactures molten salt reactor vessels for advanced nuclear systems and thermal energy applications utilizing molten salt heat transfer and storage. Our molten salt vessels feature materials and designs optimized for the unique properties and operating temperatures of various molten salt compositions used in nuclear and concentrated solar power applications.
What Are Molten Salt Reactor Vessels?
Molten salt reactor vessels are high-temperature containers designed to contain molten salt coolants or fuels at temperatures from 900°F to 1400°F in nuclear and thermal energy systems. These vessels use materials compatible with specific salt chemistries (fluorides, chlorides, or nitrates) while providing reliable containment for extended high-temperature service.

Frequently Asked Questions
What materials are compatible with molten salt service?
Material selection depends on salt type: Hastelloy N for fluoride salts in nuclear MSRs, high-nickel alloys or stainless steels for chloride salts, and carbon or stainless steel for nitrate salts in solar applications. We select materials based on specific salt chemistry, temperature, and design life requirements.
How is salt freezing addressed in molten salt vessels?
Salt freeze protection includes trace heating on all salt-wetted surfaces, insulation systems, and designs enabling complete drainage to heated storage. For nuclear applications, decay heat may assist in maintaining temperature. Proper freeze protection is critical to prevent vessel damage from salt expansion upon freezing.
What quality standards apply to nuclear molten salt reactor vessels?
Nuclear MSR vessels require NQA-1 quality assurance, ASME Section III nuclear code construction where applicable, and designs supporting NRC licensing requirements for advanced reactor concepts. We provide documentation supporting design certification and licensing activities.
