rebuilt with new seals as preventive mannite'nance. The terminal blocks for the pressurizer pressure and level control transmitters located in the containment were replaced, with Westinghouse terminal blocks. Con-trol rod power cables were checked for proper polarity and. terminal changes were made as necessary. Additional non-shutdown work included repair of a weld leak in the 1B charging pump discharge relief piping and rebuilding of a worn 1A charging pump varidrive unit.
