  • MIT NSE: Spotlight: Michael Short: From Freshman to Professor
    professor of nuclear science and engineering has made him even more of a fixture on campus since then he has introduced new classes and established the interdisciplinary Short Lab to investigate new materials for nuclear energy systems I love it here he says Short s lab is part of the Uhlig Corrosion Laboratory which is overseen by his thesis advisor and mentor Professor Ronald Ballinger Both faculty members have dual backgrounds in nuclear science and engineering and materials science and engineering Ballinger holds appointments in both MIT departments while Short has SB degrees in both disciplines an SM in materials science and a PhD in nuclear science and engineering That s a powerful combination for studying corrosion in hostile reactor environments and adhesion mechanisms that cause fuel rod fouling Short will soon complete a unique experimental facility the CRUD Loop which can precisely simulate conditions in nuclear reactor vessels and provide insights into the formation of CRUD an abbreviation for Chalk River Unidentified Deposits which accumulate on fuel rods causing decreased efficiency and shorter fuel lifetimes The Loop has been a big two year endeavor says Short It can handle 150 atmospheres of pressure like a reactor the next step is to ensure that it can maintain this at 350 degrees C Then it s time to start running experiments I can t wait The Loop includes sapphire viewing windows large enough to allow the first real time photography of CRUD formation Like many Short Lab projects the CRUD Loop has benefitted from work by Undergraduate Research Opportunities Program participants there were nine last semester Undergrads can do research as well as anyone I came to MIT myself because they let me do research right away says Short We ve had freshmen present work at international conferences and travel to Russia for research Our department provides a home for students who come out of high school wanting to make a difference why should they have to wait four years Another Short initiative aims to create a new metric for radiation damage to materials Today scientists and engineers use multiple factors to assess damage but some require destructive testing or human handling of radioactive material and reproducibility has been an issue I would like to develop a standard like the kilogram or meter for radiation damage says Short though he s quick to acknowledge easier said than done is an understatement On the teaching side Short s students in this year s Senior Nuclear Systems Design class 22 033 will face a new challenge Rather than developing conceptual designs using PC based simulation software they will analyze a complex problem void swelling in sodium cooled reactor fuel assemblies using supercomputer simulations that can take weeks to run Engineers are expected to be able to do massive simulations these days explains Short And the output will be a publishable journal article with proof of submission they ll be required to condense their thinking and get the right messages across to a broad

  • MIT NSE: Spotlight: R. Scott Kemp on rethinking nuclear security efforts
    the gas centrifuge which has become the proliferation technology of choice We studied the history of 21 centrifuge programs interviewed program technical directors from nearly a dozen nations including Pakistan and Iran and studied the technology requirements behind the centrifuge itself We concluded that while technology was once a barrier that barrier slowly disappeared in the 1970s and 1980s and today there is really no way to stop countries from producing centrifuges suitable for making nuclear weapons This is a very different conclusion than the premise upon which the United States built its nonproliferation policies back in the 1950s The engineering and manufacturing tools needed for proliferation were state of the art back then but modern technology has moved well beyond those requirements and what was once difficult is now surprisingly easy There is still a hard part however States must know how to run a research and development program History shows one or two instances namely Libya and possibly Iraq where the state seems to have been limited by its internal political bureaucratic and cultural institutions These will remain important barriers for a small subset of future proliferators and in this respect technology barriers can help exacerbate those internal limitations Q What kind of approach to nonproliferation do you recommend A My conclusion is that we need to get past the idea that we can control the destiny of nations by regulating access to technology International security must ultimately resort to the difficult business of politics To the extent that states seek nuclear weapons because of security threats we will have to work to mitigate those threats Then there are also examples in history where states were motivated to acquire nuclear weapons because of their symbolism and status This situation is more difficult We will have to consider the possibility of strengthening normative barriers to the acquisition of nuclear weapons in other words establishing social factors that increase the chances a leader will be vilified instead of worshipped for seeking nuclear weapons Fortunately there is useful precedence for normative barriers in the areas of biological and chemical weapons While a very small number of dictators have built chemical weapons in the past these states were universally shunned by the international community and ultimately suffered regime collapse leaving few states interested in attempting a repeat It should be possible to build a similar normative barrier for nuclear weapons as well although it will take time and a serious look at the utility of our own nuclear arsenal Q Your article lists more than a dozen countries that developed centrifuge technology independently Many of them such as Italy and Sweden never took the further step of building nuclear weapons Why have some countries stopped short of building actual weapons A In fact most countries have stopped short They seem to be satisfied having only the capability to build nuclear weapons just in case they need them at a future time However even though these states are weapon capable this situation is

  • MIT NSE: Spotlight: Quantum engineering
    computers and vice versa Paola Cappellaro s lab operates at the interface of basic and applied research We sometimes go more in one direction and sometimes more in the other she said Cappellaro works with nanoscale diamonds that contain a defect consisting of an embedded nitrogen atom next to a gap in the diamond crystal If you had a large enough gem quality diamond with this type of defect throughout it would be pink These nitrogen vacancy or NV centers have spins that can be readily controlled said Cappellaro who is an Associate Professor in the Department of Nuclear Science and Engineering and holds an Esther and Harold E Edgerton Career Development Professorship Atoms and electrons have a spin or orientation that s up or down similar to the two poles of a magnet Unlike ordinary magnets however atomic and subatomic spins can be a mix of up and down at the same time This superposition of spins is the source of the fuss about quantum computing If you use the up and down of a particle s spin to represent the 1 and 0 of a bit then a quantum bit or qubit is both a 1 and 0 at the same time A string of qubits therefore can represent a phenomenally large range of numbers This opens the possibility for computers that can crack virtually any secret code or search huge databases in the blink of an eye One thrust of Cappellaro s research is how information is transferred in a chain of spins Transferring information between qubits is critical for being able to build quantum computers Cappellaro said What you would like to have is not only computing units but also some wires to connect them NV centers are also potentially useful beyond quantum computing They re
