Throwback Thursday – The Lab Van ‘70s Style

TBT-2_blog sizeaugustGerald R. Ford was president. Median household income was $11,800. Gas cost 57 cents a gallon. And NRC inspectors, as part of the Independent Measurements Program, routinely hit the road in a fully equipped van containing a mobile laboratory. Inspectors measured samples of radioactive effluents from nuclear power plants, checking on the accuracy of sampling routinely done by the plants’ own laboratories.

The image directly above on the left shows an NRC inspector placing a liquid radioactive waste sample in a cryogenic detector for analysis of its isotopic composition. In the image directly above on the right, an NRC inspector reviews analytical data. A similar van, but with portable equipment, was used to verify measurements during safeguards inspections of materials facilities. During a safeguards inspection, the equipment was removed from the van and carried inside the facility for use.

Ten Things You May Not Know — About Nuclear Power and the NRC

It’s summer and you might be reading this blog while relaxing in the sun or otherwise taking it easy. So, just for fun, we’ve listed 10 nuclear-related facts you might find interesting, albeit light, reading:

1. Nothing lasts forever. Every year or two, reactor operators spend about a month, removing and replacing about one-third of a reactor’s fuel and performing various maintenance activities during plant outages to make sure reactors perform efficiently. Source: NRC Information Digest

youtube22. No bowling leagues. In order to preserve their objectivity, NRC resident inspectors are discouraged from attending social events where nuclear plant employees are involved. They also may not serve at any nuclear plant longer than seven years.

3. Who at the NRC must train to escape a sinking helicopter? Health physicists in NRC’s Region IV office of course. A handful of them must fly to inspect offshore oil rigs in federal waters. They must be prepared not only to escape a helicopter, but to survive a fire on an oil platform by jumping into the sea and fighting off sharks by kicking them in the snout.

4. Quick question: Where is the largest research reactor in the U.S.? Check below for the answer. But you should know that Research and Test Reactors operating at levels of 2 megawatts thermal (MWt) or greater receive a full NRC inspection every year. The largest U.S. research reactor, which produces 20 MWt, is 75 times smaller than the smallest U.S. commercial power reactor.

5. Once the explosive ingredient in Soviet nuclear warheads, highly enriched uranium was diluted to become the stuff that powered our homes and businesses in the U.S. The Megatons to Megawatts program was born from a 1993 agreement between the U.S. and Russia to reduce the stockpile of Soviet-era highly enriched uranium.

6. Everyone loves this story. MB900371234The most all-time viewed post on this NRC blog is “Putting the Axe to the Scram Myth” with more than 18,000 views since it was originally posted in 2011.

7. It’s just not easy being a spent nuclear fuel transportation cask. Each must be designed to survive a 30-foot drop onto an unyielding surface, a puncture test, a fully engulfing fire at 1,425 degrees Fahrenheit for 30 minutes and immersion under water.

8. The Watts Bar nuclear plant makes its mark both on this century and the last. Unit 1 was the last U.S. reactor to come online in the 20th century and Unit 2 is expected to be the first to come online in the 21st. Read more about the history of the Watts Bar Nuclear Plant in our blog post: Watts Bar – Making History In Yet Another Century.

9. Months of planning, thorough inspections, dozens of law enforcement officials, a specially equipped truck – and a S.W.A.T. team. It sounds like a checklist for an action movie. Instead it was used to move a mini refrigerator-sized irradiator in Anchorage about 2.5 miles. These small irradiators are used to sterilize medical equipment and products, and contain a sealed source of radioactive material. They are protected to keep the public and environment safe from exposure, but also to keep it out of the hands of terrorists.
