Over the past few weeks, we've been pointing to news concerning California State Assemblyman Chuck DeVore's efforts to get the state to overturn its long-standing moratorium against new nuclear build. Now we're beginning to see some bloggers stand up and support it, like Brian Wang and Kirk Sorensen.
The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.
From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.
Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

AB 719 (Devore) which would have struck down the State of California's long standing ban on new reactor construction until there is a permanent nuclear waste management plant is developed died in the California State Assembly's Natural Resource Committee on April 16, 2007.
Committee chairwoman Loni Hancock is quoted as saying that "the federal waste disposal program has been plagued with technical and legal challenges, managerial problems, licensing delays, persistent weaknesses in quality assurance for the program, and increasing costs."
The Devore bill claimed to address the need to reduce carbon dioxide emissions to curb global warming. According to the California Energy Commission, the most significant reductions in CO2 emissions from electricity generation can be achieved through energy efficiency programs and integrating renewable energy resources -- solar, wind, thermal, biomass and hydropower-- into electricity supplies.
