Hey Ralph, The reason the French program looks so good has less to do with the actual program than with the government's policies toward nuclear and the press. To be sure, the French program has had its share of burps, including a couple of fairly interesting sodium-water reactions at Super-Phoenix. But lacking 1st Amendment restrictions, the government can and does control what the French press reports. Not by some censor board but by letting its wishes be known to the publishers. My experience with French visiting engineers is that I know more about French nuclear operational matters via the US nuclear press than they do. Closely related to that is that Electricite' de France (the French national utility) simply doesn't communicate operational details to the lay media. They don't have to and they don't. The fact that all French power stations are owned by a single utility makes the matter even easier than here with thousands of little utilities, each with its own PR mouthpiece. Though I've never sat down and counted tit for tat, my impression is that the French nuclear program has has more incidents than the American one including several involving core melt. Simply because the military keeps most things secret, most folks have no idea how many catastrophic reactor accidents there have been. There have been a BUNCH. The SL-1 accident is one of the few that gained any publicity. In this one, the operators manually lifted the control rod until the reactor went prompt critical. The instantaneous power production, estimated in the gigawatt range, caused a steam explosion that destroyed the reactor and killed all three men present. The water hammer sheared off all coolant pipes and the reactor vessel settled down several feet under its normal location. From a radiological standpoint, this accident was still insignificant. Even without a sealed containment, radioactive material was detected only a couple hundred yards away from the site. In a little over a year, the reactor was removed and the ground it was on now registers normal background. John |
