What was the scope of the program and the approximate costs to develop the program? Were there any unexpected problems encountered while developing the program?

Song: No.

Question: Do your NDE procedures include a methodology for calculating the examination coverage for limited examinations, and if so, how is this calculation performed and what considerations are included?

Song: Currently we are developing an in-house procedure for calculating exam coverage. We are trying to make it as simple and straight forward as possible.

Question: Does your plant share any calibration blocks on a regular basis with other plants outside of your organization, and if so, what types of blocks do you share and who do you share them with?

Question: As outages become shorter and shorter, how are you able to handle your ISI workload during the outage? Are you supplementing your staff with additional temporary personnel or are some tasks getting deferred?

Question: What type of software do you use to track and analyze ISI program commitments and inspection data? Was the software developed by your organization or purchased from a vender? Does it adequately meet your needs? If not, why not?

Song: Our current ISI software was developed by Raytheon. Not very useful. In the process of purchasing a off-the-shelf product (IDEAL).
