Modern Industries Technique Company (MITEC) is responsible for design and construction of the IR-40 heavy water reactor in Arak;

2.2.3. The mist shall be produced by means of the steam generator described in Appendix 4 of Annex II. The generator shall contain enough water to generate at least 70 ± 5 g/h of steam for each seating position designated by the manufacturer, in an ambient temperature of – 3 °C.

8402 | Steam or other vapour generating boilers (other than central heating hot water boilers capable also of producing low pressure steam); super-heated water boilers | Manufacture: from materials of any heading, except that of the product, andin which the value of all the materials used does not exceed 40 % of the ex-works price of the product | Manufacture in which the value of all the materials used does not exceed 25 % of the ex-works price of the product |

The Agency has technical expertise with the full spectrum of nuclear reactors designs, including light water reactors, heavy water reactors and graphite-moderated reactors.

The Candu's advanced heavy water design allows it to use 28% less natural uranium than light water designs found in the United States and in Russia and produces much less waste which has to be disposed of.

4.1. Steam distillation apparatus consisting of:1. a steam generator; the steam must be free of carbon dioxide; 2. a flask with steam pipe; 3. a distillation column; 4. a condenser.This equipment must pass the following three tests:(a) Place 20 ml of boiled water in the flask. Collect 250 ml of the distillate and add to it 0,1 ml of 0,1 M sodium hydroxide solution (3.2) and two drops of the phenolphthalein solution (3.3). The pink colouration must be stable for at least 10 seconds (i.e. steam to be free of carbon dioxide) (b) Place 20 ml of a 0,1 M acetic acid solution in the flask.
