Nuclear Issues

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

"...[Y]es, I think Stuxnet had a few down sides. One of those down sides was that the actual attack code became publicly available. As far as I can tell the attack code was supposed to die and not get out onto the Internet, but apparently the same way it got into Natanz [Iranian nuclear enrichment facility], it got out...."

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR．The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid／small size fossil plants economically．This paper reviews the history and current status of SMR and ASPWR，and also discusses the design concepts, safety features and other advantages thereof.

"The conventional wisdom among those who looked at the Middle East used to be that you had a choice either of supporting the autocrat or being stuck with the religious extremists. The extraordinary diffusion of information created in Egypt and other Middle Eastern countries reveals a strong middle that we weren't fully aware of. What is more, new technologies allow this new middle to coordinate in ways unseen before Twitter, Facebook, and so forth, and this could lead to a very different politics of the Middle East. This introduces a new complexity to our government's dealings with the region."

Hui Zhang argues that China's pledge of no-first-use of nuclear weapons, while constraining its nuclear force at a minimum level, maintaining its deeply de-alerted status, and upholding its long-standing position to support complete nuclear disarmament, has set a good example for other nuclear nations, in particular the two nuclear superpowers.  Zhang suggests that Beijing believes that all nuclear states should adopt a no-first-use policy and redefine the role of nuclear weapons in their national security doctrines. Although China stands ready to support the nuclear-free agenda, it is up to the two countries with the overwhelming number of the world's warheads to take the lead.

"...[A] primary goal in the next decades must be to remove this risk of near global self-destruction by drastically reducing nuclear forces to a level where this outcome is not possible, but where a deterrent value is preserved — in other words, to a level of minimum deterrence. This conception was widely discussed in the early years of the nuclear era, but it drowned in the Cold War flood of weaponry. No matter how remote the risk of civilization collapse may seem now — despite its being so vivid only a few decades ago — the elimination of this risk, for this century and centuries to come, must be a primary driver for radical reductions in nuclear weapons."

Hui Zhang argues that an effective universal Fissile Material Cutoff Treaty (FMCT) would make an important contribution to nuclear disarmament, the nonproliferation regime, and the prevention of nuclear terrorism. However, such a FMCT must have a credible verification regime. Dr. Zhang suggests that it should be technically feasible to establish an effectively verifiable FMCT at a reasonable cost, while protecting national security secrets.

"...China is worried about how U.S. space weaponization plans might affect Chinese national security, international security, and protection of the space environment...."
