Since soaie of these radiographs were found to be enhanced, this matter was reported to the NRC as a potentially reportable deficfericy under 10CFR50.55(?).

The following provides the information specifically requested by the Bulletin under Action to Be Taken by Holder of Active Construction Permits:

A review of ITT Grinnell radiographs that were at the job site as of November 24, 1982 has been conducted. As a result, forty-two welds (involving 70-radiograph film) showed enhancement.

ITT Grinnell has been airected to perform complete reradiography on these forty-two welds.

If reradiography is not possible due to present configuration, an engineering disposition will be made and the necessary corrective action will be implemented.
