Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

Equipment and techniques have been developed for the fabrication of fill tube surrogate targets for OMEGA experiments. The fill tube is attached manually by heating 4000 MW poly--methylstyrene in a fixed reservoir, which can be touched onto the capsule surface and pulled into the shape of a fill tube. The joint is uniform and robust with diameters no less than 20 m. A series of surrogate fill tubes can be achieved by modifying temperature and technique with a diameter reproducibility within 5 m. After attachment, the capsules are mounted onto a calibrated stage to trim the length of the surrogate to specifications. Characterizing the surrogates involved positioning the polymer stalk to measure the fillet diameter, stalk diameter, and length at orthogonal orientations. Details of the heating and pulling techniques will be dis- cussed as well as a description of the polymer reservoir.
