INDEPERDENT NCSDESTRUCTIYE EXAMINATIOt STU3T REPORT Enclosed for your infomation is our final report pertaining to the Independent 3::nduMive Exa:tination Study. The report was prepared by Mr. W. Laudan of my staff who was the pm.m coerdinater for this

stucy, Region I and II representatives assisted in contractor surveillance and test result evaluations at 3 Mile, Island #2 and Watts Bar il anJ 2 sites rerpectively.

This study was perfemed to determine the feasibility of NRC:IE conducting independent exs=1 nations of pressure retainirrg cannonents and piping by perfomance of voliretric and surface nondestructive examir.ations.

From the results sf this study we recomend that ultrasenic testing, magnetic particle exacaination and liquid penetrant surface examinations be continued utilizing an HRC-IE-MDE task force.

It is recrx= ended that radiographh be continued on a periodic basis through the use of outside ccntractors.

At this time we rectncend proceeding with the develcpment of an UT, FT and MT task force on a small scale possible under the jurisdiction of PAT.

Althcugh we have made a good start and have gained pertinent experience per'aining to licensees responses, tining of exwinations, code applications, record quality and the logistics of manipulating NDE equiptent, we reca:x::end proceeding on a s:nall experimental scale utilizing flexible procedures that can be modified to meet our needs as they become more precisely defined.
