External Work on Pakistan Plutonium Reactor Looks Nearly Done

A heavy-water reactor at Pakistan's Khushab nuclear complex in April 2008. Recent satellite images indicate the exterior of a fourth plutonium-production reactor at the site is almost finished.

The ex­ter­i­or of Pakistan’s new­est plutoni­um-pro­duc­tion re­act­or ap­pears al­most com­plete, though it is un­clear when the re­act­or will be up and run­ning.

Satel­lite pho­to­graphy cap­tured as re­cently as Nov. 1 “clearly shows that the ex­tern­al con­struc­tion of the fourth re­act­or build­ing [at the Khush­ab nuc­le­ar com­plex] ap­pears nearly com­plete,” Ser­ena Kelle­her-Ver­gantini and Robert Avagy­an find in an In­sti­tute for Sci­ence and In­ter­na­tion­al Se­cur­ity re­port pub­lished on Fri­day.

However, the im­agery also shows that a “con­sid­er­able amount of ad­di­tion­al con­struc­tion” re­mains un­der way at the re­act­or site, ac­cord­ing to the re­port.

Is­lamabad does not provide up­dates to the in­ter­na­tion­al com­munity on the status of ef­forts to ex­pand its fis­sile-ma­ter­i­al pro­duc­tion cap­ab­il­it­ies. That leaves the pub­lic just a few sources of in­form­a­tion about the pro­gram, such as com­mer­cial-satel­lite im­ages.

“Giv­en that satel­lite im­agery provides lim­ited in­dic­a­tion of the re­act­or’s op­er­a­tion­al status, pre­dict­ing when the fourth re­act­or will be­come op­er­a­tion­al is dif­fi­cult,” write Kelle­her-Ver­gantini and Avagy­an.

The fourth re­act­or ap­pears to have a lay­out slightly dif­fer­ent from the two re­act­ors that im­me­di­ately pre­ceded it at Khush­ab. Con­struc­tion of the new heavy-wa­ter re­act­or has also moved at a more slug­gish pace than was earli­er pre­dicted. This could be the res­ult of work­ing out the kinks of a new re­act­or blue­print or for an en­tirely dif­fer­ent reas­on that can­not be de­tec­ted by satel­lite, ac­cord­ing to the IS­IS re­port.

The space-based sur­veil­lance did not turn up any signs that work had be­gun on a po­ten­tial fifth plutoni­um re­act­or at Khush­ab, the au­thors noted.

Pakistan is be­lieved to be grow­ing its plutoni­um-pro­duc­tion ca­pa­city in or­der to al­low it to ac­quire an ar­sen­al of plutoni­um-fueled war­heads. Its cur­rent nuc­le­ar ar­sen­al uses urani­um-based war­heads.

Congress Passes Chemical Regulations Overhaul

The House on Tuesday voted 403-12 "to pass an overhaul to the nation’s chemical safety standards for the first time in four decades. The Frank R. Lautenberg Chemical Safety for the 21st Century Act aims to answer years of complaints that the Environmental Protection Agency lacks the necessary authority to oversee and control the thousands of chemicals being produced and sold in the United States. It also significantly clamps down on states’ authorities, in an effort to stop a nationwide patchwork of chemical laws that industry says is difficult to deal with."
