Nuclearn Search
An AI agent for your plant's documents and public NRC and DOE sources. It reads the documents themselves and answers with citations to the page.
Illustrative exampleWhich of six NRC Regulatory Guides refer to 10 CFR 50.55a: yes or no for each file, with the pages and a citation for every reference. Learn more →Specialist tools
Each takes one job further, on the same platform as AtomAssist: one sign-in, the same documents and permissions. Each has its own site with screenshots and details.
Nuclearn CAP AI
Write a complete condition report in plain words. CAP AI screens it against your own codes and procedures with the reasons shown, and your screeners keep the decision.
Illustrative exampleA synthetic condition report graded on when, while, who, what and the consequence, with five similar past reports beside it. Learn more → Performance improvement teamsNuclearn Performance Improvement AI
Codes your condition reports against WANO performance objectives and criteria, shows which codes stand out by unit, department or quarter, and builds the trend report.
Illustrative exampleA quarter's condition reports trend-coded against WANO criteria, the codes that stand out by unit and department, and the trend report on your Word template. Learn more → Licensing engineersNuclearn Regulatory AI
Works a proposed change through 50.59 applicability, screening and the eight evaluation criteria against your UFSAR and tech specs, and drafts the report in Word.
Illustrative exampleA proposed change worked through applicability, screening and the eight evaluation criteria, with a challenge agent questioning each answer before the Word draft. Learn more → EngineeringNuclearn Engineering AI
Drafts review reports on your own Word template from an RFP, specification or requirements, with citations, and splits the work by discipline for you to approve.
Weeks → days of analyst time on one safety analysis report section, for a Nuclearn customer drafting on the Nuclearn platform. Learn more → System and equipment engineersNuclearn Equipment AI
Reads your sensor trends, work orders, condition reports and operator rounds, scores each piece of equipment with the evidence behind the score, and checks PM intervals against the industry PM basis.
Illustrative exampleA pump in a simulated plant scored critical: a repeat bearing work order open 157 days, both bearing temperature channels not responding, and overdue PMs. Learn more → Procurement engineeringNuclearn Parts AI
Drafts the item equivalency evaluation when a part goes obsolete, stopping for the engineer at every decision. It also looks for where to source a part and makes your parts catalog searchable by what a part is.
Illustrative exampleA demo 3-inch Class 600 gate valve and its replacement: critical characteristics compared from both data sheets, and two evidence gaps flagged for the engineer. Learn more → Outage planners and schedulersNuclearn Work AI
Finds the logic ties that set your outage finish date and runs your P6 schedule thousands of times with durations learned from your past outages. It also tags work orders capital or expense.
$800K+ in missed capitalization, found on a first pass over about 10,000 of a Nuclearn customer's work orders. Learn more → Operations and system engineersNuclearn Link for P&IDs
Turns the P&ID PDFs and scans you already have into one connected plant. Scope a clearance across sheets and see what any valve or pump ties into.
Illustrative exampleA valve's isolation boundary traced across two public P&ID sheets, with the nine valves to close numbered on both. Learn more → Document controlNuclearn Document Library
Nuclearn Connect brings procedures, vendor manuals, drawings and licensing documents in from the document management systems your plant already uses. Scanned pages are read with OCR.
Illustrative exampleA 1974 regulatory guide that exists only as a scan, found by a search for monthly operating report contents and opened at the page. Learn more → Simulator and engineering teamsNuclearn Simulator AI
Puts a full-scope plant simulator under AtomAssist's control. Replay an event, try a what-if or describe a scenario in plain words: it writes the scenario file, checks it against the simulator's own lists, runs it and tells you what the plant did.
Illustrative exampleThe simulator in Nuclearn's lab also runs a simulated plant, and Equipment AI reads that plant's historian.

Illustrative examples use public, demo or synthetic data, as on each product's page.
Building a plant? Start with its corrective action program.
A new plant needs a corrective action program before it has the people to run it. Nuclearn runs your CAP as a managed service, under your license and QA program, on the Nuclearn platform, and the records stay yours.

Every job runs on the same documents.
Screening a condition report, writing a 50.59, building a work package and finding a replacement part all draw on the same procedures, past condition reports, the UFSAR, drawings and vendor manuals. A tool built for one of those jobs leaves your people stitching the rest together by hand, and the people who know where everything is are needed in five places at once.
Much of that work is reading. INL found that planning work, including searching out and compiling the right documents, is over 42% of what work management costs.1
Nuclearn reads across all of it on one platform and takes on the first draft, so your people spend their time on the decisions.

Start with a paid pilot on one job.
Teams working from uploaded documents are typically live in 2–4 weeks from contract. Connections to your systems of record follow your IT and cyber review, and Nuclearn plans that schedule with your IT contact before kickoff. Every product runs on the Nuclearn platform, with the same sign-in, roles and permissions.
Pick the first job
CAP screening, a 50.59, an engineering review, an outage schedule, a drawing set or a document search. The pilot runs on that one job, with the people who do it.

Built for nuclear, by people from nuclear.
Nuclearn's founders worked at a US nuclear plant, where their team built machine learning for plant operations and received NEI's Top Innovative Practice award in 2020. They started Nuclearn in 2021 to bring that work to other plants.
Our products start from the jobs plants already do, in the plant's own words and on its own documents.

Questions plants ask first.
Will it make things up?
Answers and drafts point back to the page, passage or record they came from, so your people can check each one before they rely on it. Screeners, engineers and planners keep every decision. Nuclearn does the reading and the first draft.
Does it fit how our QA and licensing work?
Nuclearn products prepare screenings, evaluations and drafts for your people to review and approve under your own procedures, the way they would a colleague's work. The sources stay with each result. We'll walk your QA and licensing staff through how the product you start with fits your process.
Does it work with our document system?
Documents come in by upload, or are synced by Nuclearn Connect from systems such as SharePoint, file shares, CMIS repositories, Maximo, Aras Innovator, OpenText Documentum and IBM FileNet. Connect runs in your network and makes outbound HTTPS connections only.
What does it cost?
Each product is an annual subscription, priced for your site, with setup, support and upgrades included. Nuclearn scopes the first year around the jobs your team owns. What it takes →
How long does it take to get going?
Teams working from uploaded documents are typically live in 2–4 weeks from contract. Connections to your systems of record follow your IT and cyber review, and Nuclearn plans that schedule with your IT contact before kickoff.
Where does our data go?

Does it work alongside Microsoft Copilot?
Yes. Nuclearn works on your plant's own records and nuclear jobs, such as CAP screening, 50.59s and P&IDs, with citations to the page and revision, in your plant's own instance. Nuclearn Link for P&IDs has an MCP server, so approved AI assistants can query the connected drawings.
