When atmospheric carbon dioxide (CO 2), or carbonate ions (HCO − 3, CO 2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide (portlandite, Ca(OH) 2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite).
The test assembly is a self-contained vehicle, that can contain fuel or materials for a variety of reactor types. [14] These test assemblies, also referred to as test vehicles or test loops, can simulate the conditions of a light water reactor, heavy water reactor, liquid metal fast breeder reactor, or a gas cooled reactor.

It was built to test the concept of a heavy water moderated and cooled reactor for civilian power. It was tested from late 1962 to December 1964. [1] It was not restarted. The fuel was removed and the facility was secured by 1971. All auxiliary buildings were removed. The reactor building awaits its final disposition. [2] [3]
The TR-2 nuclear reactor, also known as the Westinghouse Test Reactor or Westinghouse Testing Reactor (WTR) was a small research and test reactor designed and manufactured by Westinghouse Electric Corporation at their Waltz Mill site near Madison, Pennsylvania, approximately 30 miles southeast of Pittsburgh. TR-2 was the first privately owned ...
TEPCO finished removing all spent fuel rods from a cooling pool at No. 4 reactor in 2014 and from the No. 3 reactor pool in 2021. It plans to complete removal of the rods from the No. 1 and No. 2 ...
This resulted in partial or complete meltdown of fuel rods, damage to fuel storage pools and buildings, release of radioactive debris to surrounding area, air and sea, and resorting to the expedient use of fire engines and concrete pumps to deliver cooling water to spent fuel pools and containment. During the incident, pressure within the ...
