Nuclear Issues

Since 2015 China has shown it is quickly modernising its nuclear force through adding more and “better” intercontinental ballistic missiles (ICBMs) and multiple independently targetable re-entry vehicles (MIRVs).Based on Chinese publications and Western governmental and non-governmental estimates, this author estimates that in 2020 China has a total inventory of approximately 360±50 nuclear warheads. This stockpile is likely to grow further over the next decade as additional nuclear capable missiles become operational. In particular, China nuclear force modernization has been driven mainly by expansion in US missile defence programmes as many Chinese believe. China’s arsenal may be somewhat larger than France’s but is much smaller than the US and Russia.

Does a lack of enthusiasm for nuclear energy among the U.S. public relate to connections with nuclear weapons? A critical area of public opinion remains understudied: the connection between nuclear energy and nuclear weapons. Scholars have theorized such a relationship in the public consciousness, but the premise has not been systematically investigated. The authors use two studies which provide evidence of psychological linkage. In fact, attitudes toward nuclear weapons may even drive those on nuclear energy.

An outstanding scholar, extraordinary mentor, and a community builder, Martin Malin passed away on April 19. His warmth, humility, and kindness made him more than a colleague and a close friend to many.

Horizontal nuclear proliferation presents what is sometimes referred to as the "Nth country problem," or identifying which state could be next to acquire nuclear weapons. Nuclear fuel cycle technologies can contribute to both nuclear power generation and weapons development. Consequently, observers often view civilian nuclear programs with suspicion even as research on nuclear latency and the technological inputs of proliferation has added nuance to these discussions. To contribute to this debate, the author puts forth a simple theoretical proposition: En route to developing a civilian nuclear infrastructure and mastering the fuel cycle, states pass through a proliferation "danger zone."

I do not think it’s likely that Kim Jong-un will conduct another test of ICBMs—since Trump had repeatedly drawn a bright red line there. Kim Jong-un and his experts would rightly be worried that were they to cross this line, especially in an election season, Trump would respond by attacking North Korean ICBM launch sites—as he’s signaled he would do. 

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

Over the last decade, China has been actively pursuing plans to recycle its spent nuclear fuel. In 2010, it began testing a pilot civilian plutonium reprocessing plant with a design capacity to produce about 50 metric tons of heavy metal per year at the Jiuquan nuclear complex in Gansu province (known as Plant 404). In July 2015, the China National Nuclear Corporation started construction of a larger demonstration reprocessing plant at the Gansu Nuclear Technology Industrial Park in Jinta, Gansu Province, about 100 kilometers from the Jinquan pilot plant. The demonstration reprocessing plant, which has a planned capacity of 200 metric tons per year, is to be commissioned in 2025.
