'....e December 3, 1981 MEMORANDUM FOR:
Robe'rt Warnick, Director', Enforcement and Investigation Staff FROM:
Russel J. Marabito, Public Affairs Officer
SUBJECT:
PERRY ALL$ CATIONS FROM NEWS MEDIA Eileen Cory, a reporter for WEW3-TV in Cleveland,will be doing a report on Perry NPS tonight (December 3) as an outgrowth of the recent problems at Perry involving a 4 :fective weld and the stop work on cable pulling.
Ms. Cory talked to me yesterday, and again today, about a couple of allegations she received from a workman while her camera crew was filming on site. She said as che was leaving Perry a workman told her all was not well at Perry, and gave her a couple of allegations. He said he would call her later with more specifics, but at this writing, he has not telephoned her. In her report on Perry tonight, she is going to say she was given some allegations and has passed them on to the NRC for investigation.
The two allegations given to her I-and as she gave them to me---were:
(1) there is no concrete in two areas of the biological shield in Reactor Building 2.
(2) there was a steel crack that was covered up at 599 in Reactor Building 1.
She added that she heard there was some question on whether the piping contractor Newport News, was using the proper welding techniques. But she didn't know anything more than that.

Perry Nucicar Power Plant Docket Nos. 50-440;50-441 Interim Report on Biological Shield Walls Heavy Density Concrete. Units 1 and 2
[RDC 34(81)]
Dear Mr. Keppler:
This letter serves as a second Interim Report in accordance with 10CFR50.55(e) concerning the heavyweight concrete in the Biological Shield halls of both Reactor Buildings. The first Interim Report, submitted on August 14, 1981, indicated that the final report would be submitted to the NRC by December 18, 1981.
Mr. L. McGregor was informed on December 16, 1981, by Mr. G. Leidich cL The Cleveland Electric Illuminating Company that a second Interim Report would be submitted in lieu of the final report, which will be submitted at a later date.
This report includes a description of the condition, testing method and preliminary evaluation, and the planned date for the final report.
Description of Deficiency Light, chalky material, up to three inches (3") thick, was observed at the top construction joints of the heavyweight bioshield concrete placements, for Reactor Building 1 - elevation 654' and for Reactor Building 2 - elevation 630'.
This material has a bulk specific gravity of approximately 75 pounds per cubic foot, rather than 195 pounds per cubic foot per the specified design requirement. Additionally, this material is soft enough to scratch with the fingernail ano contains no ferrous aggregate. Due to inaccessability, only three of twenty-four cells in Reactor Building 2 could be visually inspected for this material.
It could not be readily determined if this material ever existed at the top construction joints of any of the previous heavyweight placements.
