Playing Fast and Loose with Nuclear Substances: a missing radioactive capsule

In the Australian Outback, authorities are engaged in an unusual search-and-recovery effort. Gone missing is a capsule less than an inch long of radioactive material that can burn or sicken anyone who touches it. Their problem is that it could be anywhere along a 900-mile stretch of highway connecting a Rio Tinto PLC mine to Perth, Western Australia’s state capital…The capsule, which is 8-millimeters (about 5/16s of an inch) long and contains a small quantity of radioactive Cesium-137, worked its way loose from a piece of equipment that Rio Tinto had sent to Perth by truck for repair.

The tiny capsule fell along a route that is almost the distance between New York and St. Louis. Complicating the search effort is a gap of nearly two weeks between when the equipment left Rio Tinto’s Gudai-Darri mine on Jan. 12, 2023 and when the capsule was discovered to be missing on Jan. 25… Authorities worry the capsule could have become lodged in a tire of any of the vehicles that use the highway, potentially exposing their occupants to radiation levels that they compare to receiving around 10 X-rays in an hour. Exposure could cause radiation burns or severe illness, said Andrew Robertson, Western Australia’s chief health officer.

Normal Nuclear Accidents

In March 2022, a nearly tragic accident involving India and Pakistan pointed to another path to nuclear war. The accident highlighted how complex technological systems, including those involving nuclear weapons, can generate unexpected routes to potential disaster—especially when managed by overconfident organizations.

India and Pakistan possess more than 300 nuclear weapons between them, and have fought multiple wars and faced many military crises. On March 9,2022 three years after their dispute over Kashmir escalated into attacks by jet fighters, the Pakistan Air Force detected “a high speed flying object” inside Indian territory change course and veer suddenly toward Pakistan.* It flew deep into Pakistan and crashed. The object was a BrahMos cruise missile, a weapon system developed jointly by India and Russia. India soon stated the launch was an accident.

The firing of the BrahMos missile falls within a long history of accidents involving military systems in India. Military aircraft have strayed across the borders during peacetime. India’s first nuclear submarine was reportedly “crippled” by an accident in 2018, but the government refused to divulge any details. Secrecy has prevented the investigation of an apparent failure of India’s ballistic missile defense system in 2016. Engagements between India and Pakistan can arise from such accidents, as in 1999 when a Pakistani military plane was shot down along the border by India, killing 16 people. Pakistan has had its share of accidents, including a Pakistani fighter jet crashing into the capital city in 2020.

All these weapons systems are inherently accident-prone because of two characteristics identified by organizational sociologist Charles Perrow decades ago—interactive complexity and tight coupling—that combine to make accidents a “normal” feature of the operation of some hazardous technologies. The first characteristic refers to the possibility that different parts of the system can affect each other in unexpected ways, thus producing unanticipated outcomes. The second makes it hard to stop the resulting sequence of events. For Perrow, “the dangerous accidents lie in the system, not in the components,” and are inevitable.

Perhaps the best and most troubling proof of this proposition is in the realm of nuclear weapons—which embody all the properties of high-risk technological systems. Despite decades of efforts to ensure safety, these systems have suffered many failures, accidents and close calls. During 1979–1980, for example, there were several false warnings of Soviet missile attacks, some of which resulted in U.S. nuclear forces being put on alert.  

Given the secretive nature of Indian nuclear policymaking, little is known about India’s nuclear command and control system. However, the 1999 Draft Nuclear Doctrine called for “assured capability to shift from peacetime deployment to fully employable forces in the shortest possible time.” The combination of technology and plans for being able to rapidly launch nuclear weapons raises the risk of accidental and inadvertent escalation to nuclear war.  

South Asia’s geography is pitiless. It would only take five to 10 minutes for a missile launched from India to attack Pakistan’s national capital, nuclear weapon command posts or bases….Compounding these dangers is the overconfidence of India’s officials, who displayed no recognition of the gravity of the Brahmos accident.

How to Shh! a Nuclear Accident: the explosion of a nuclear-powered cruise missile on August 8, 2019, Russia

Two days after the explosion of a suspected nuclear-powered cruise missile undergoing testing on Aug. 8, 2010 near Nyonoksa Russia, two monitoring stations nearest the site of the accident stopped transmitting data, Lassina Zerbo, who heads the Comprehensive Nuclear Test Ban Treaty Organization, told The Wall Street Journal.  The Russian monitoring stations, called Dubna and Kirov after the places where they are located, were contacted immediately about the data disruptionl, and Russian officials responded that they were experiencing “communication & network issues.”

The missile test, on a platform in Dvinsk Bay on the White Sea in northwest Russia, has been the subject of considerable speculation. President Trump has said it involved an advanced nuclear-powered cruise missile, which has been dubbed Skyfall by the North Atlantic Treaty Organization, and which Russia calls Burevestnik.

The manned monitoring stations are part of an international network of hundreds of stations set up to verify compliance with the Comprehensive Nuclear Test Ban Treaty, which prohibits nuclear weapons tests globally. Participating nations are responsible for running the stations…The stations are designed to monitor everything from seismic shifts to sound waves for signs of nuclear activity. The two stations that went silent in Russia are designed to measure radioactive particles in the atmosphere…Arms-control experts said the monitoring problem appears to be a Russian effort to conceal information about the accident and not an effort to hide evidence of a prohibited nuclear weapons test.

Nuclear Submarines on Fire (2)

Vladimir Putin has confirmed  on July 4, 2019  that the top-secret submarine that suffered a deadly fire was nuclear-powered, but Russia’s defence minister said the nuclear unit had been sealed off and was in “working order.”  The incident, which left 14 Russian sailors dead,  The Russian government has been slow to reveal information about the incident because the submersible, thought to be a deep-diving vessel used for research and reconnaissance, is among Russia’s most secret military projects.  The fire aboard the “Losharik” AS-31 submersible began in the battery compartment and spread through the vessel…The vessel is thought to be made of a series of orb-like compartments, which increase the submersible’s resilience and allow it to dive to the ocean floor. Once there, it can perform topographical research and participate in rescue missions. It may even be able to tap and sever communications cables on the seabed.

Officials claim the submariners sealed themselves in one of the compartments to battle the blaze and toxic fumes…A Norwegian official told Reuters there had been no “formal communication” from Russia about an incident aboard a nuclear-powered vessel, but “we would have been happy to have been informed of such incidents”….Accidents aboard submarines invariably evoke comparisons to Putin’s clumsy handling of the sinking of the Kursk nuclear submarine in 2000, which left 118 dead and families desperate for information about their loved ones.
