China’s Fissile Material Production and Stockpile

IPFM 12th Jan 2018, IPFM’s new research report “China’s Fissile Material Production and
Stockpile” (PDF copy) by Hui Zhang uses information from newly available
Chinese public sources to provide a more detailed and documented
reconstruction of China’s production of highly enriched uranium (HEU) and
plutonium for nuclear weapons.

The report provides new evidence to constrain the operating histories for China’s Lanzhou and Heping gaseous
diffusion enrichment plants. Lanzhou stopped HEU production for weapons in 1980 and shifted to making low enriched uranium (LEU) for civilian power reactors and possibly for naval reactors. It was shut down on 31 December
2000 and in 2017 was demolished.

The Heping plant may still be operating but not producing HEU for weapons. China also has centrifuge enrichment
plants but they are believed not to produce HEU for weapons. The new report also offers new details on the operational experience of the Jiuquan and Guangyuan weapon plutonium production reactors. China also used these
reactors to produce tritium for weapons. The reactors were closed in the 1980s and have been undergoing decommissioning.

Energy efficiency – theme for July 2019

Energy efficiency represents the single largest potential contributor to global emissions reduction, according to the International Energy Agency (IEA 2017). It should be a key part of the global energy strategy, for several reasons:

It could reduce global electric demand by more than 20 per cent, based on current rates in the U.S. power sector, while maintaining high levels of services such as heating and lighting.
It avoids the need for increased energy, capacity and grid services, making it the least expensive way to decarbonise at scale.
It can reduce carbon dioxide emissions by billions of tonnes.

A dramatic example of the power of energy efficiency is lighting. In 2017 the United States passed the milestone of 1 billion LED and CFL lights installed, avoiding 142 million tonnes a year of carbon dioxide emissions, at a cost of about $7 per ton of avoided carbon dioxide. In contrast, the cumulative installed capacity of rooftop solar reached 8,000 MW in 2017, saving 8 million tonnes a year of carbon dioxide, at a cost of $360 per ton. Lighting efficiency thus yielded almost 18 times the avoided carbon dioxide, at about 2 per cent the cost per ton of rooftop solar.

Google provides another example of the power of energy efficiency. Its data centers now use 50 per cent less energy than the average data center, according to the company. Google also developed an improved chip, the TPU, which performs 83 times better than standard CPUs. The new chip allowed Google to reduce power consumption at its data centers by a factor of 30—far exceeding the effect on Google’s carbon footprint of all of the company’s renewable energy purchases. ” – John Woolard, Eco Business, 10 June 2019
