Canadian Terror and Pickering Nuclear Power Station – Don’t Worry
BY Herschel Smith
Over at the Counterterrorism blog (linked in this site), you will find that there was concern that the Jihadists recently captured in Canada were targeting Pickering Nuclear Power Plant.
American nuclear reactors have to be designed with an overall negative power coefficient. According to 10 CFR Part 50, Appendix A, general design criterion 11:
The reactor core and associated coolant systems shall be designed so that in the power operating range the net effect of the prompt inherent nuclear feedback characteristics tends to compensate for a rapid increase in reactivity.
Translation: when an incident happens (let’s say, a loss of reactor coolant), the nuclear design of the reactor must be such that without any assistance or interference from humans, the reactor tends to decrease power and shut itself down.
The CANDU reactors in Canada are not U.S. design nor do they have to meet U.S. Code, but they do have a negative overall power coefficient like U.S. reactors. Also like U.S. reactors, they have strong containment and reactor building designs, as well as serious, heavily armed security, truck barricades and other impediments to vehicular threats.
The very worst that the Jihadists could cause would be some serious financial damage to the reactor site in terms of peripheral equipment (such as step-up transformers, switchyard equipment, etc.). They could not get close enough even to damage the reactor building structure, much less to cause a release of radioactivity. And even if all of this did happen, the reactor shuts down because that is the way it is designed.
Shopping malls, drinking water supplies, bridges, tunnels … these things are soft targets. A nuclear power plant? Too hard. They wouldn’t even get close. No worries. Security did its job and the Jihadists were caught. Around nuclear power plants they always will be.
