NATS 1840 – Lecture 15 – Nuclear Power and Design Momentum - Nuclear reactors produce power without significant greenhouse gas emissions, because of this, they are often put forward as a “green” technology - The current dominant model of power production, large-scale, centralized, distributed power, also fits well with nuclear reactors - However, nuclear technology is not popular, and has not been successful on a worldwide scale - It is generally agreed that nuclear reactors have been much more expensive than expected - From an environmental perspective, there have been serious concerns expressed about nuclear waste and nuclear safety Waste Concerns - Nuclear waste is a serious concern, as it lasts for thousands of years before becoming benign, however, relative amounts should be kept in perspective - For example, in France: nuclear waste approximately 1.2 kg per person per year, 100kg of toxic industrial waste, 15kg of hospital waste, 3000 kg of non-toxic industrial waste, and 700kg of agricultural waste - Uranium mining produces waste products that have not always been safely stored, for example, uranium waste has been used in building construction, spent uranium shell casings - There have been many suggested solutions for dealing with radioactive waste, disposal in space, deep burial (underground and underwater), mixing waste with glass and sealing it in steel containers - Reprocessing of fuel has also been pursued, using reactors to transmute the - harmful isotopes in the fuel into shorter lived materials - One of the key problems with waste management is the life span of nuclear

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
