Second Shif t k'elding Inspection Nape --

As a result of the investigation of the " foreman overide" issue, a review of the past practices of assigning welding inspectors to second or other off shifts was done by Catawba site QA management. This review is summarized here.

QA Procedures provide for required inspections of welding activities depending on the QA Condition of the items being welded. For higher QA Condition items more inspections are required and work is procedurally prohibited from continuing until those inspections are completed and found acceptable. The procedures also allow for random inspections during the process of welding. A statement was made that sometimes very little time was available on the second shift for random inspections by the welding inspector.

The key factors in determining the number of welding inspectors needed for coverage of work are (1) the number of welders working (2) the QA Condition work being done and (3) the location of the work. In the past first line welding inspection supervising technicians made the decision.

sometimes daily, as to how many inspectors would be needed on 2nd shift.

This was appropriate because of their communications with crafts involved and knowledge of the work to be done on second and third shifts and where it j

was located. It was not unusual for work to be scheduled to continue on

! second shift late in the first shift of the same day.

ihis was and is the appropriate decision making level becau's) of the shorter lines of communications. However, this sometimes results in more inspectors than are needed or less inspectors than are needed. L' hen less inspectors than needed are available all required inspection's are still i

done and the work may be delayed as a result, however, the a~ mount of l random inspections is obviously less. k' hen more inspectors are present then there is opportunity for more than average random inspections. This type variation from time to time is inherent in the nature of work on a project of Catawba's size and complexity. Since random inspections are just that, random, this variation is not a problem. Inspections necessary to be performed are documented as hold points and those are completed regardless of the number of inspectors available. >

l Re: Catawba 1-2 2nd and 3rd Shift Welding Inspection in the past the number of welding inspectors assigned to the 2nd shif t has been dependent upon the number of welders assigned to the shift and the number of inspections which could be expected as a result of the type of work being performed. Since most of the workload is on the 1st shift, the 2nd shif t was staffed to the minimum necessary to support craft needs. Routinely, this would be one or two inspectors who concentrated on the areas of heaviest activity and were summoned by beeper to other areas when inspections were required. Occasionally, craf t would work personnel on 2nd shif t without notifying QA inspection of their presence until an inspection was required. Work load varied but as time permitted, checks were made on work in different areas.

Since 2nd shif t has become a normal craf t routine, the QA inspection sec-tion has organized to have first line welding inspector supervision rotating to the 2nd shift. Emphasis has been placed on the need for surveillance,and inspector visibility in areas where welding is being performed and the shif t is staffed in order to accomplish this end.

If work is distributed so that routine presence of an inspector is not necessary, the supervisor will ensure that random rounds in the work areas are made either by himself or an ' inspector during the shif t.

Whether or not the 2nd shift continues to be of a size requiring a supervisor, inspector staffing and instructions will be such that random surveillance will and can be a part of the shif t routine.
