Hallam Sodium Graphite Reactor photos

2023-06-03

The photos below come from the decommissioning process of the Hallam Nuclear Power Facility, a Sodium Graphite Reactor that operated in Hallam, Nebraska between 1963 and 1964. Decommissioning activities pictured here took place between 1967 and 1969. The originals are sitting in the office at Sheldon Power Station. After visiting the site and looking through the albums, I asked Nebraska Public Power District if they’d be willing to scan them (and also sponsor the digitization of a related film). They graciously agreed and sent me the scanned PDF. Special thanks to Scott Margheim and John McClure at NPPD for all the efforts in getting this done. We cropped the images and transcribed the captions to get them into this form.
