Washington Public Power Supply System (WPPSS)

A two-sided punch-out toy model of a Helium atom, produced by the Washington Public Power Supply System, with English on one side ("THE ANATOMY of an ATOM") and Spanish on the other ("La Anatomía de un Átomo").

Three illustrated cards showing the Washington Public Power Supply System's "NUCLEAR PROJECT NO. 3." This was also known as "WNP-3." This project was started in the mid-1970's, was halted in 1983, and was terminated in 2007.
this project was located at Satsop, near Elma, WA.

An illustrated card showing "NUCLEAR PROJECT NO. 1" of the Washington Public Power Supply System, otherwise known as "WNP-1." This project began in the 1970s, was halted in 1982, and was terminated in 1994.
This project was located on the Hanford site.

Five unused postcards showing "Plant 2" of the Washington Public Power Supply System at the Hanford site in Richland, WA.

Six cards with affixed "simulated fuel pellet", describing the energy contained in a pellet of this size (about 0.625" long, 0.375" diam.) and noting that Plant 2 of the Washington Public Power Supply System generates enough electricity to serve more than 350,000 homes.
The other side is an image of Plant 2 at the Hanford Site.

A lithograph produced by the Washington Public Power Supply System (WPPSS) of the "Nuclear Project No. 1." This print was produced likely in the mid-1970s.
This project is also known as "WNP-1" — a partially built nuclear plant located on the Hanford Site. This was authorized in the 1970s and left at roughly 63% completion in 1982 due to soaring costs and falling demand. The unfinished concrete structure remains under Energy Northwest's management.
