} Inputs
| Field | Type | Req | Default | Description |
|---|---|---|---|---|
mode | string | no | "export" | export: every licensing record published in a date range, filtered by record type, state, company and keyword. lookup: the full history of the docket numbers, plants or companies you list (all years since 2000 unless you set dates). |
lookups | array | no | [] | One per line: a docket number (50-317, 05000317, 52-047), a pre-application project number (99902137), a plant name (Calvert Cliffs) or a company name (Constellation Energy, TerraPower). |
lookup | string | no | — | One docket number, plant or company, for saved tasks and API calls that send a single value. Use Lookups above for several. |
recordTypes | array | no | [] | Which records to return. Empty means all three. One per line: amendment_request (a licensee asked to amend an operating reactor's licence); amendment_issued (the NRC issued an amendment); new_reactor (construction permit, combined licence, early site permit and limited work authorization notices, hearings and decisions). |
lastDays | integer | no | 90 | Records published in the Federal Register in the last N days. Empty: the last 90 days in export mode, all years (since 2000) in lookup mode. 0 means all years. Ignored when a 'From' date is set. |
dateFrom | string | no | — | YYYY-MM-DD, inclusive, by Federal Register publication date. The Federal Register's full text starts in 2000. Overrides 'Last N days'. |
dateTo | string | no | — | YYYY-MM-DD, inclusive. Empty means up to today. |
states | array | no | [] | Keep only plants in these states (two-letter code or name, e.g. IL or Illinois). Empty means every state. |
state | string | no | — | One state, for saved tasks and API calls that send a single value. |
companies | array | no | [] | Keep only records whose licensee, applicant or plant name contains one of these (e.g. Constellation, Dominion, Vogtle). |
keywords | array | no | [] | Keep only records whose description contains one of these words (e.g. steam generator, cyber security, power uprate, emergency plan). |
includeLicenseeContact | boolean | no | true | For amendment requests and new-reactor notices, read the application's cover letter in the NRC's ADAMS library and add the person the licensee named for questions (name, phone or email). Costs nothing extra; turning it off makes large runs faster. |
maxResults | integer | no | 200 | Cap for the run in export mode, and for EACH lookup in lookup mode. Records come newest first. |
Pricing
Pay per result (record) — no charge for empty runs.
Example: 1000 licensing records at $0.005/result ≈ $5.00.
FAQ
What is covered?
Every entry in the NRC's biweekly (earlier monthly) Federal Register notices of licence amendment requests and issued amendments for nuclear power reactors, from 2000 (where the Federal Register's full text starts) to the latest notice, plus the NRC's new-reactor notices: construction permit, combined licence, early site permit and limited work authorization applications, their hearings and decisions. Measured on 2026-11-01, the last 365 days held 387 records: 190 amendment requests, 170 issued amendments and 27 new-reactor notices.
Where do the contacts come from, and how often is there one?
Three places. The licensee's own contact (the person named for questions in the application's cover letter) comes from that letter's text in the NRC's ADAMS library; in the 365-day export on 2026-11-01 it was found for 137 of 190 amendment requests (72%) and 19 of 27 new-reactor notices, mostly a name and direct phone, sometimes an email. The attorney's name and mailing address are printed in the notice (176 of 190 requests). The NRC project manager's name and phone are in the notice (184 of 190); new-reactor notices give NRC staff with email. Issued amendments carry no contacts.
How does lookup mode work?
List docket numbers (50-317, 05000317, 52-047), pre-application project numbers (99902137), plant names (Calvert Cliffs) or company names (TerraPower). Each one returns its records from every year since 2000 unless you set dates. On 2026-11-01, docket 50-317 returned 213 amendment records from 1998 to 2026 and Clinch River returned TVA's early site permit and construction permit notices from 2017 to 2026.
Do repeated notices show up twice?
An amendment request that the NRC re-publishes in a later notice is returned once per run. New-reactor notices are returned per notice, so a limited work authorization notice the NRC publishes four weeks running appears four times, each with its own Federal Register number and date.
How fresh is it?
Each run reads the Federal Register as it stands, so the newest biweekly notice is in the next run. A saved task with 'Last N days' set to 14 picks up each new notice.
How am I charged?
$0.005 per licensing record. The licensee's contact from ADAMS costs nothing extra. Free rows (input to fix, no match, a source that did not answer, a stopped run) are never charged. 'Maximum records' caps the run (and each lookup).
