4.4.3.2.4 In addition to the requirements of Specification 4.0.5 the repair welds and adjoining areas of the pressurizer relief line shall be examined, using improved UT detection and evaluation procedures which have been demon-strated to be effective in detecting IGSCC, prior to entering MODE 4 whenever the plant has been in COLD SHUTDOWN for 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months or more if the examination has not been performed in the previous 6 months.

In the event these 6-month period examinations find the piping free of unaccept-i able indications for 3 successive inspections, the inspection interval shall be extended to 36 month intervals (1 12 months to coincide with a scheduled refueling outage).

In the event these 36-month period examinations find the piping free of unacceptable indication; for 3 successive inspections, the inspection interval shall be extended to 80-month periods.
