Mustard Gas factory

[Gordon WR]

The latest trip saw me at The Valley Works Rhydymwyn last week for a wander round.
Situated in the Alyn valley just outside Mold this area has been locked down since 1939 when work started to build a plant to manufacture mustard gas. The gas was
manufactured,loaded into munitions then charged with explosives and fused here.Both types of gas, Runcol and Pyro were produced here.
At its peak a total of 2,200 people worked here all sworn to secrecy under the official secrets act. So effective that the Germans never found out about the plant
In 1941 a building was used for the Tube Alloys atomic programme,with one of the scientists being Klaus Fuchs. In 1950 he was sentenced to 14yrs in prison for espionage after leaking secrets to the Russians.

The valley site was divided into separate areas with the manufacture and filling area kept apart from the charging and fusing area. In the charging area all the buildings had flat roofs that were designed to blow off in the event of an explosion, entry here being strictly controlled to maintain a spark free and safe compound.

The railway siding came in here, this being the platform where the munitions were sent onwards by train.
