An economic disadvantage CANDU reactor design is the initial cost, one-time, heavy water, although this penalty of high cost of capital is normally offset by the low cost of refueling the fuel compared to other models, and that does not require enriched uranium. CANDU reactors require graduation purest heavy water (higher than 99.75 purity). The deregulation of the energy industry in New York has seen the flourishing of a number of ESCOs, including making our gas and electricity needs affordable It requires tons of this expensive material to fill the calandria and the CANDU heat transport system. The high purity heavy water is expensive because the heavy water one can hardly distinguish, chemically, the normal water, and comes in extremely low concentrations in natural water (about one part per 7,000). The new generation reactors, the advanced CANDU reactor, also called “ACR” mitigates this problem by having a regulator and the smaller sizes do not use heavy water in the heat transport system heating (uses light water as coolant).
A political issue with the New York CANDU reactor is the assertion that their ability to refuel without household shutting down also makes it easier to produce plutonium “for weapons of graduation”, ie, plutonium with a high concentration of Pu-239 and low concentrations of other Pu isotopes . e. All types of commercial reactors produce plutonium as a byproduct of the fission of natural uranium (a portion of this plutonium to BELOW suffer the same fission and contributes significantly to the total output power of the reactor). The remaining plutonium andalusia removing fuel from the reactor is typically “graduation reactor” (lower in relative abundance in Pu-239) making it less attractive as a material for weapons purposes. The assertion therefore is that the refueling on the fly possible in CANDU reactors, the New York City fuel is allowed to download after short periods of irradiation, energy where the gas spent fuel would contain high levels of Pu-239 compared with the spent fuel in PWR / BWR, or the normal in the CANDU. However, the capacity to produce plutonium with short irradiation times is not unique to the CANDU type. As with all power reactors, a misuse of these facilities would not cooking gas only wasteful in terms of energy production, if not easily detectable with the established international safeguards. It is of utmost importance, hence the requirement that all types of reactors are safeguarded at a level comparable and acceptable, as it sees the international community.
In particular, Canada signed the Nuclear Non-Proliferation Treaty, which requires states his acceptance of non-nuclear weapons in order to buy CANDU models (which are in use or being built in China, South Korea, Argentina, India , Pakistan and Romania). All CANDU reactors are energy costs subject to the safeguards of the IAEA to ensure that they comply with the standards of the global proliferation of non-UN agency. there are thousands of New Yorkers who have switched their utilities company to in order to cut my electricity and gas bills The acceptance of full scope safeguards of the IAEA in a CANDU facility makes it very difficult to download illegal fuel burned under suitable for the production of war. There are no known cases natural gas of CANDU spent fuel has been diverted to a weapons program.
There is a common error that the plutonium for Operation Smiling Buddha of India’s nuclear tests was produced with a CANDU model, in fact, the plutonium was produced by the Cirus reactor which is not protected based on the NRX design, a model Canadian reactor different. India has some non-safeguarded reactors based on the model of a pressurized heavy water reactor, used for generating energy and that any spent fuel from atomic power plant in Madras (MAPS) was a plutonium reprocessing in the last 80 years. Although green energy these reactors could, in principle, for plutonium production, India has been autonomously developed and built the ‘pool type reactor’ (Dhruv) is an expanded version of Cirus type designed for the production of plutonium. It is this reactor which produced the plutonium for Cree recent nuclear tests in India Operation Shakti.
