How to run NRC Reactor License Applications & Amendments Tracker

You open this actor when you want to know which U.S. nuclear plants have asked the Nuclear Regulatory Commission to change their operating licence, and who to talk to about it. The NRC announces every request in a Federal Register notice every two weeks, roughly 6 to 11 requests a notice, and each entry names the plant, the dockets, the dates, the licensee’s attorney and the NRC project manager. The person at the plant who handles the request is named somewhere else: in the cover letter of the application, which you find by its ADAMS number in the NRC’s document library. This guide runs the export the listing uses as its example: every amendment request from the last 90 days.

What you’ll need

Nothing but an Apify account. The actor talks to Federal Register + NRC ADAMS directly.

No API key of your own and no proxy. The Federal Register needs no key. The NRC’s ADAMS search API does, and the actor uses ours, so the licensee contact costs you nothing extra and you never sign up with the NRC.

Step 1 — Open the actor

Step 2 — Fill in the input

Field	Type	Required	What it does
mode	string	no	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… (default export)
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,… (default [])
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… (default [])
lastDays	integer	no	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…
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. (default [])
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). (default [])
keywords	array	no	Keep only records whose description contains one of these words (e.g. steam generator, cyber security, power uprate, emergency plan). (default [])
includeLicenseeContact	boolean	no	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… (default True)
maxResults	integer	no	Cap for the run in export mode, and for EACH lookup in lookup mode. Records come newest first. (default 1000)

Two fields decide most of what comes back. recordTypes picks the kind of record: amendment_request is a plant asking for a change (this is where the contacts are), amendment_issued is the NRC granting one, and new_reactor is the construction permit, combined licence, early site permit and limited work authorization notices for plants that do not exist yet. Leave it empty for all three. lastDays (or dateFrom / dateTo) is the Federal Register publication date, not the date the plant applied: a request filed in April can appear in an October notice. Empty means the last 90 days in export mode.

Lookup mode answers the other question. Set mode to lookup and put docket numbers (50-317 or 05000317), plant names (Calvert Cliffs) or company names in lookups. Each returns its records from every year unless you set dates; docket 50-317 returned 213 amendment records from 1998 to 2026 on 2026-11-01.

A working input:

{
  "lastDays": 90,
  "recordTypes": [
    "amendment_request"
  ],
  "maxResults": 200
}

Step 3 — Run it

Press Start. Rows are pushed to the dataset as they’re found, so the run log fills in as it works.

Without the 200-row cap, the input above returned 51 amendment requests from 8 notices on 2026-11-01, in under 6 seconds, measured outside Apify through one proxy. A full year of all three record types was 387 records in 38 seconds. Our first run on Apify, three rows from a test account, finished in 11 seconds. A single “no_match” row means nothing matched in that window: widen the dates or drop a filter. A “blocked” row means the Federal Register did not answer, and a “contacts_unavailable” row means the ADAMS read failed, so the licensee-contact columns are empty while everything else is complete. Notice rows are never charged.

Step 4 — Read the output

Each run returns a labelled table, not raw JSON:

Every row looks like this — a real row from a real run:

{
  "record_type": "amendment_request",
  "licensee": "Constellation Energy Generation, LLC",
  "facility": "Calvert Cliffs Nuclear Power Plant, Units 1 and 2",
  "docket_numbers": [

    "50-318"
  ],
  "state": "MD",
  "county": "Calvert County",
  "application_date": "2026-09-29",
  "description": "The proposed amendments would update the applicability of the Reactor Protective System Rate of Change of Power-High (RCPH) trip function...",
  "proposed_determination": "NSHC",
  "licensee_contact_name": "Adam Donell",
  "licensee_contact_phone": "267-533-5156",

  "adams_accession_numbers": [
    "ML26272A139"
  ],
  "fr_document_number": "2026-21832",
  "fr_publication_date": "2026-10-27",
  "source_url": "https://www.federalregister.gov/documents/2026/10/27/2026-21832/biweekly-notice-applications-and-amendments-to-facility-operating-licenses-and-combined-licenses"
}

Field	Example value	Meaning
record_type	amendment_request	amendment_request, amendment_issued or new_reactor
licensee	Constellation Energy Generation, LLC	The licensee or applicant
facility	Calvert Cliffs Nuclear Power Plant, Units 1 and 2	The plant and units
docket_numbers	["50-317", "50-318"]	NRC docket numbers (50-317) or a pre-application project number
state	MD	Two-letter state of the plant (plus county)
application_date	2026-09-29	When the licensee applied (requests), with any supplement dates
issued_date	—	When the NRC issued the amendment (issued), with the amendment numbers
description	The proposed amendments would update the applicability of the Reactor Protective System Rate of Change of Power-High (RCPH) trip function...	What the amendment would change, or the new-reactor notice’s summary

Most people come for the three contacts. licensee_contact_name and licensee_contact_phone are the person the plant named in its cover letter “if you have any questions”; in that 90-day run 38 of the 51 requests had one (35 with a phone, 3 with an email), and licensee_contact_source is the ADAMS number of the letter it came from. It is empty when the letter names only its signer, nobody, or is a scanned image. attorney_name with the split attorney_mailing_address, city, state and ZIP is printed in the notice itself (48 of 51), and nrc_contact_name with nrc_contact_phone is the NRC project manager (49 of 51). Issued amendments carry no contacts; they carry amendment_numbers and issued_date instead. An entry that covers several plants (Farley in Alabama and Vogtle in Georgia, for example) lists every docket in docket_numbers and every state in states.

Step 5 — Export it

Open the Dataset tab and export to CSV, JSON, or Excel — or pull the same rows from the API, which is what you want if this is going to run on a schedule.

What it costs

$0.005 per licensing record, whatever its type. The licensee contact costs nothing extra, and notice rows are free. The example input returned 51 records on 2026-11-01, which is $0.26. A full year of every record type was 387 records, $1.94, and a plant’s whole history by docket number was 213 records, $1.07.

Where the data comes from

This reads Federal Register + NRC ADAMS directly. The target is The Federal Register’s documents API and full-text XML for NRC notices (labelled prose 2000-2020, two-column tables 2021 on), plus the NRC’s ADAMS Public Search API for the application cover letter’s text. Every night a canary runs this actor against that live source and diffs the result against a frozen fixture — what “verified” means.

Everything here is public and free to read. The work is in the shape: until 2020 each notice is prose paragraphs (“Date of amendment request:”, “Attorney for licensee:”), from 2021 it is two-column tables, some years leave the table titles blank, and the same request can reappear in a later notice. The contact sits in a second system, ADAMS, as the text of a letter.

NRC licence amendment requests with licensee contacts turns the last 90 days of requests into a call list for a firm that sells to plant licensing teams.

If the companies you are after are newly funded startups rather than nuclear plants, Recently Funded Companies Lookup & Leads Scraper (SEC Form D) reads another federal filing feed with the people named on each filing.
