It is believed by some that the large requirements of tritium that Orange Herald needed ( actually it contained only a small amount of thermonuclear material ) was a major cause of the Windscale fire . It was unpopular with the scientists who worked on the project . One of the workers in the British nuclear program , Dr. Bryan Taylor , is quoted as saying " I thought that Orange Herald was a stupid device . It was n't elegant , it could n't be developed any further , it was a dead end design . And it consumed an enormous amount of very expensive fissile material . " . This is the thesis of a BBC documentary on the topic of the fire , '' Windscale : Britain ’s Biggest Nuclear Disaster ''
