Ultra Safe Nuclear
Ultra Safe Nuclear Corporation (USNC) was a Seattle-based advanced nuclear company, founded in 2011, that vertically integrated fourth-generation nuclear power — the Micro Modular Reactor (MMR), the Pylon space reactor developed through its USNC-Tech subsidiary, and Fully Ceramic Microencapsulated (FCM) TRISO nuclear fuel manufactured at Oak Ridge, Tennessee. It filed for Chapter 11 bankruptcy in the District of Delaware in October 2024 following the death of its principal investor, and its assets were sold in a bifurcated Section 363 auction: NANO Nuclear Energy acquired the MMR and Pylon reactor patents and demonstration partnerships for $8.5 million (court-approved 18 December 2024), and Standard Nuclear acquired the FCM/TRISO fuel business and the Oak Ridge facility for $28 million (closed February 2025). The company no longer operates. Its primary domain, usnc.com, is still registered and still routes mail on the Microsoft 365 US Government cloud but publishes no address record, so the corporate web presence is gone. As a reactor and nuclear-fuel manufacturer it never ran a developer program, and no public API, specification, SDK, or agent surface was found under its name.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Ultra Safe Nuclear the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Ultra Safe Nuclear scores 4.0/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Ultra Safe Nuclear Corporation was liquidated in a Chapter 11 Section 363 auction completed in February 2025, and its corporate domain usnc.com now returns NXDOMAIN with no address record while still routing mail on Microsoft 365 US Government cloud, so there is no site, portal, or API host left to probe.
This is an honest zero, not a gap in our research. Ultra Safe Nuclear does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Ultra Safe Nuclear
Each block below is one kind of artifact we hold for Ultra Safe Nuclear. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Ultra Safe Nuclear, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
