How can "fiscal conservatives" support taxpayer subsidies to the nuclear industry?!

Although it won't be known for sure until next month, Alaska's Republican U.S. Senator, Lisa Murkowski, may have just lost to "Tea Party" insurgent candidate Joe Miller in yesterday's primary elections. Murkowski, and her father and predecessor in the same U.S. Senate seat, Frank Murkowski, have been top pro-nuclear power champions from their perch atop the Senate's Energy and Natural Resources Committee dating back over a decade. (The elder Murkowski, in fact, was strongly criticized for nepotism when he, just elected Governor of Alaska, tapped his own daughter to fill his own just vacated U.S. Senate seat!) But Tea Party candidates, including kingmaker Sarah Palin herself, are very pro-nuclear power in their own right. For example, Tea Party candidate Sharon Angle in Nevada, challenging Senate Majority Leader Harry Reid, has advocated reprocessing at Yucca Mountain in lieu of radioactive waste disposal there -- an activity that wouldn't require underground containers to eventually fail and leak over time, but would rather spew large amounts of harmful radioactivity directly into the environment in real time! And Palin herself, whose endorsement of Miller may have put him over the top in his campaign against Murkowski, has lambasted Reid and President Obama for their opposition to the Yucca dump in Nevada. So a Murkowski ouster may not signal any let up in pro-nuclear efforts to expand nuclear power and open radioactive waste dumps in the U.S. Senate, by any means, if they are simply replaced by equally pro-nuclear power Tea Party candidates! How Tea Party candidates can support taxpayer subsidies for new atomic reactors, and exorbitantly expensive government programs such as the Yucca Mountain dump or reprocessing facilities, given their supposed fiscal conservatism and concern for protecting taxpayers, is difficult to reconcile! Similar questions have been asked of currently serving supposedly "fiscal conseratives" in the U.S. Senate who also support massive taxpayer subsidies for new reactors in the form of risky federal loan guarantees.
