Blades-in turbine inspections at Quad Cities set new benchmark for Constellation
When Constellation decided to install replacement Alstom low-pressure turbines at three of its boiling water reactor plants more than 15 years ago, one benefit was knowing the new turbines should operate reliably—and without major inspections—for several years.

The uptake of tritium by tungsten and its release behavior have been investigated. Specimens annealed at 773 K, 873 K, 973 K, 1,073 K and 1,173 K for 3 hours and loaded with tritium at 773 K for 3 hours accumulated 0.125 ppm, 0.068 ppm, 0.067 ppm, 0.038 ppm and 0.033 ppm, respectively (tritium solubilities were 3.6x 10-9 at.fr.Pa-1/2, 2.0x 10-9 at.fr.Pa-1/2, 1.9x 10-9 at.fr.Pa-1/2, 1.1x 10-9 at.fr.Pa-12/ and 9.7x 10-10 at.fr.Pa-1/2, respectively). The difference is attributed to the existence of trapping sites or oxide films.
