Enclosure:

(A) Ultrasonic Thickness Measurement Report-' Summary r% The Nuclear Engineering Department requested that specific areas of the-. primary containment drywell liner plate be measured for wall thickness

.(NESR-.ber 86-03). The request cited the NRC Information Notice 86-99, and the General Electric Company RICSIL No. 09 as alerting utilities of possible corrosion of the drywell liner material.

The drywll liner plate was ultrasonically examined, with no degradatioh'ýby corrosion found.t)I Discussionr In response to reference (a) a plan was established to:.&o Obtain the required measurements.

f C.Provide additional scanning surface in the event further evaluation.

was required.o Optimize the examination technique for both wall thickness and pitting corrosion.

Twelve 6" by 6" areas were prepared for ultrasonic examination at elevation 91 -2'. This area was chosen to allow scanning for pitting :. '...r--7 '. other techniques such as angie ueam if further evaluation were required.

DOC selected the scope ultrasonic instrument, as opposed to a digit.' instrument, to allow for more detail evaulation of the ultrasonic signal, such as lamination and pitting.KRELEASED JAN309B7 0ORU" R' ROUfWtI CONTROL COPY Dept. DOC. Dae awr 1 97P-To: Dt:Jnay2,16 t
