Nuclear & radioactive-waste intellectual property

Patented by design.
Built as a system.

NuclearSAFE's nuclear-technology portfolio spans deep geologic disposal, engineered waste forms and capsules, deep caverns, emplacement and retrieval, repository closure, siting, and difficult radioactive waste streams. These NuclearSAFE patents are non-duplicative.

Public U.S. patent record review current through August 21, 2026. Non-nuclear inventions are intentionally excluded.

30 Distinct U.S. grants

A platform—not a single patent

IP across the nuclear back end.

The portfolio reflects a systems-engineering strategy: protect the waste form, create the disposal architecture, control emplacement and retrieval, close the repository, and address difficult radioactive-waste streams. Unpublished applications are intentionally excluded and can be added later when publication or disclosure is strategically appropriate.

Repository / SuperLAT® Deep horizontal wellbores, site selection, salt, onsite disposal and repository closure.

Waste Form / CinGOT™ HLW/SNF capsules, container systems and newer metal-matrix waste-form concepts.

Caverns / SuperSILO® Deep human-made caverns and volumetric geologic-disposal architectures.

Operations / Retrieval Self-loading systems, linked capsules and retrieval tools.

Specialized Waste Vitrification, uranium products, UF₆, LLW and radioactive munitions.

Counting method: one granted U.S. legal right is shown once. A pre-grant application publication is not separately shown after that application has matured into a listed patent. Separate issued continuation-family patents remain separate granted rights.

Select any patent number to open its public patent record. Most links use Google Patents; the three newest grants use verified Justia patent records while Google indexing is unavailable. The 1998 and 2001 patents are displayed as foundational historical disclosures; current enforceability and chain of title should be confirmed separately during legal diligence.

Ownership & institutional diligence

Inventorship, assignment and enterprise ownership are different questions.

Henry Crichlow is the inventor of record on most of the portfolio; Henry Crichlow and Gary Schneider are co-inventors on the self-loading family; and Gary Schneider is inventor on the retrievable-capsule family, for which public records identify NuclearSAFE Technology LLC/NuclearSAFE Technology as assignee. NuclearSAFE plans to consolidate appropriate rights into a separately controlled IP holding company. Before transfer and final public launch, chain of title, assignments, maintenance status, prosecution history and encumbrances should be reconciled against official USPTO records and executed agreements.

Broad IP. One integrated nuclear mission.
