Twenty years on, he spent much of what remained of his late wife Margaret's fortune the main source of financing for the excavation on reconstructing bits of the palace in reinforcedconcrete, then a fashionable new building material.
Another Cardiff firm, Bluebay Building Products supplied reinforcedconcrete for the bridges and highways being built on the Olympic Park, while Rhino Doors from Port Talbot won a contract at the start of the project for entrance doors for the power lines tunnelling project.
The reactor vessels remained intact as did the reinforcedconcrete containment buildings, but each reactor building lost its hat due to the hydrogen explosions.
Both the drywell and the wetwell are surrounded by a secondary containment vessel (or shield building) also built from reinforcedconcrete about a meter thick.
