  • In situ weld repair of blade tenon of steam turbine in a power plant

    During one of the routine inspections in a nuclear power plant, it was found that a tenon of one of the third-stage blades of the Low-Pressure (LP) turbine had been worn/broken off the turbine blade, leaving only the remaining tenon riveted to the shroud piece. With only one of the two tenons remaining, the blade was at risk of getting freed from the shroud piece. Hence, it was necessary to ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
