The objectives of Tasks 1 and 2 of RP 1398-5, Cracking of Steam Turbine Discs, are to identify key variables for cracking in bores and keyways and in rim attachments of shrunk-on discs used in low-pressure (LP) rotors in US nuclear power plants. A review was conducted of available data concerning disc cracking experience in other countries, factors governing stress corrosion cracking of low-alloy steels, and factors determining environments present in LP turbines. Disc cracking experience in US plants were determined from a survey of US utilities and a series of visits to utilities.
