Washington, Jan 17:

US-based Institute for Science and International Security has said that Pakistan’s fourth heavy water reactor at Khushab nuclear site, which allows it to build a larger number of miniaturised plutonium-based nuclear weapons, is now operational.

KHUSHAB NUCLEAR REACTORThe reactor is a part of Pakistan’s programme to increase the production of weapons-grade plutonium.

“A recently purchased Digital Globe high resolution satellite image dated Jan 15, 2015 shows that Khushab’s fourth reactor’s external construction is complete and has become operational,” David Albright and Serena Kelleher-Vergantini of the institute said in a statement Friday.

“This assessment is based on the presence of a very specific signature, steam is venting from the reactor’s cooling system,” the statement said.

Albright and his co-author said Pakistan’s Khushab nuclear site, located 200 km south of Islamabad, is dedicated to the production of plutonium for nuclear weapons.

“Its expansion appears to be part of an effort to increase the production of weapons-grade plutonium, allowing Pakistan to build a larger number of miniaturized plutonium-based nuclear weapons that can complement its existing highly enriched uranium nuclear weapons,” the statement said.

“Originally, the site consisted of a heavy water production plant and an estimated 50 megawatt thermal (MWth) heavy water reactor, both of which became operational in the 1990s. However, Pakistan initiated the construction of a second heavy water reactor between the years 2000 and 2002, a third one in 2006, and a fourth one in 2011,” it added.

Noting that Pakistan has never provided public information regarding any of the Khushab reactors, Albright and Kelleher-Vergantini said therefore the power output can only be estimated.

The Institute for Science and International Security estimates the power of the original heavy water reactor to be about 50 MWth while reactors Two, Three and Four are believed to generate double or more the power of the first one, and are thus capable of producing more than double the amount of weapons-grade plutonium per year.

A technical consultant to the US-based institute with years of experience in heavy water reactors assessed that the power of these newer heavy water reactors is likely to be more than the first one and over time, their power could be further increased.

The Dec 2014 and Jan 2015 imagery also shows that the third Khushab reactor is also operational, since steam is venting from the cooling system. IANS
