In the event of a catastrophic leak in the Atomic Energy of Canada Limited (AECL)NPD-2 boiler room the pressure will rise rapidly. Calculations indicate that this pressure rise will not exceed 5 psi, which is the maximum design pressure of the building. In order to confirm these calculations a 1/4 scale model of the boiler room and relief duct were made. The relief duct was sealed with 1/4 inch thick herculite glass with an explosive attached to it which was fired by means of electrical circuit through a microswitch actuated by the pressure rise. When these microswitches were set to close at 1.2 psi the pressure rise did not exceed the design limit of 5 psi. (auth)
