A framed (30 cm by 39 cm), bulletin from the Pakistani Post Office describing a postage stamp issued in 1972 in honour of the Karachi (KANUPP), CANDU-type reactor. The power station, later known as KANUPP-1, was a 137 MWe unit that was connected to the Pakistani power grid in October 1973. The reactor, whose design is similar to the Douglas Point reactor in Canada, was built by Canadian General Electric. With Pakistan’s refusal to becoming the party of the Nuclear Proliferation Treaty (NPT), GE Canada halted the sales of spare parts, natural uranium, heavy water, and technical support for the nuclear power plant in 1976. Details of the stamp design and colours are described in the brochure.
