Generic Adams

An Adams import was set up so that new correspondence will be imported periodically. If we can add context then we could better organize the letters into relevant groups. Ie groups around project codes.

Findings

Plants undergo inspections by the NRC. A series of pages have been uploaded representing the findings that resulted from those inspections. This is a good data set because it helps show a practical interpretation of regulation. In other words, who knows what it really means but this is how it was done wrong.

Scrams

One of the bigger events for a plant is a Scram. The occurrence of which are reported to the NRC via the ENS system. By extracting that information you can get lists of data. Please see the main page Scram.

Mapping

Recently Mapping has been incorporated to the wiki. Mostly its about plant locations and can show corporate owner icons. It is feasible to overlay a set of data with locations (ie you can see where ENS occurred on a Map).

Emergency Notification System

First successfully integrated database is the Emergency Notification System. It is a database which holds all the short-term notifications made by nuclear power plants (10 CFR 50.72). If you visit the Emergency Notification System you can see how digitizing the ENS can lead to a variety of customized reports and notifications.

ENS 58069	Summer	Feedwater Decay Heat Removal Emergency Feedwater System	The following information was provided by the licensee via phone and email: As allowed by 10 CFR 50.73(a)(1), VC Summer Nuclear Station (VCSNS) is making a 60-day notification of an invalid actuation under 10 CFR 50.73(a)(2)(iv)(A). At 0948 EDT, on October 3, 2025, VCSNS commenced a shutdown to repair a steam line leak. On October 4 at 2116 EDT, VCSNS was in mode 3, with the 'A' motor-driven emergency feedwater (EFW) pump providing decay heat removal. Main feedwater (MFW) had been secured per standard operating procedures. The deaerator storage tank (DAST) experienced a level decrease due to secondary-side valve leak-by. When the DAST level reached low-low level, an automatic signal was generated to secure the already secured MFW Pumps, which automatically sent an actuation signal to EFW. The low-low DAST signal is intended to secure MFW pumps to prevent damage due to a potential loss of net positive suction head at lower DAST levels. This sequence resulted in the invalid actuation of the previously secured 'B' EFW pump. This actuation was not in response to an actual engineered safety feature (ESF) condition and does not meet the criteria for a valid ESF actuation. This event is being reported as a 60-day report in accordance with 10 CFR 50.73(a)(1) for an invalid actuation of the EFW System. The NRC Senior Resident Inspector has been notified.
