J. G. Keppler-February 27, 1985 CORRECTIVE ACTION TAKEN In January, 1984, Phillips Getschow installation and inspection procedure, PGCP 30, was revised to include all specification requirements for new installations.
For previous installations, the instrument retrofit verification procedure, QCP 32, was developed to reinspect and rework, as necessary, all safety related ASME section III and Class H instrument installations, and review associated documentation to ensure that these installations conform to the specification requirements.
This program is currently. underway and is expected to be complete by March 31, 1985.
We expect that a final report will be submitted by May 1, 1985.
Please address any questions that you or your staff may have
- concerning this matter to this office.
Very truly yours,
