PRESSURIZED THERMAL SHOCK (A-49) LONG TERM PROGRAM Task 1: Development of a Rewmed Regulatory Guuse 1.99 Draft rewmaon of the trend curves in Reg. Guxse 1.99, Revision 1. " Effects of Residual E'wwnents on Predcted Radia-tion Damage to Haector Vessel Materiais":This task is no longer consusered to be necessary for completion of A49. Its scheduled completion is a kwger term item than A49, and adequate guasance regac:hng this subsect is contained within Task (B). A dotaded schedule for this task is therefore no* preser tod. Task 2: Ongoing Program to improve Procedures and Operator Training The program is ongoing separate from the A-49 PTS effor! and is much broa&w than PTS, consusenng PTS as one of the many types of incidents for which procedures and training arumid be improved, on a ccmbined/ integrated bass. Generic Letter 82 33 contains a desenption of the overall pmgeam and schedule. The PTS effort cannot and should not be separated from the overaN of%rt, and so a detailed PTS schedule is not presented here. The ongoeng program wiB be compisted and applied to each plant, hcwever, on a schedule cornpattle with completion of the finet PTS resolution for each plant (i.e., before acceptance of plant specift analysse required by the PTS rule. Task (8) above.)
