SUBJECT:
ALLEGED DEFICIENCIES DESCRIBT IN THE HOUSTON POST
[
ARTICLE BY HAROLD SCARLETT, DATED 2/24/80 2
SOUTH TEXAS PROJECT, UNITS 1 & 2, DN 50-498; 50-499 To the best of my knowledge, the following alleged deficiencies at the South Q
Texas' Project described in the Houston Post article have not been investigated:
f s
L 1.
"There was, for example, that embarrassing hole or void, all the way I
through a 30-inch-thick radiation shielding wall. inside the Unit 1
'g reactor building."
b.
"A deficiency report on. February 2, 1978, noted that when concrete pour forms were removed, a 24-by-30-inch hole was found entirely
-2 threr,tgh the wall. A photo shows nothing in the open space except bare reinforcing bars."
6
=_
2.
"A non-compliance report on November 28, 1978, described another disturbing discovery."
j "The west outside wall of the Unit 1 mechanical and electrical building was out of plumb, tilting almost an inch and a half to one side."
+
i "The " corrective action," as outlined in the report, was to " taper" It higher pours on the wall to bring it back to construction tolerances."
=
3.
"Other deficiency and non-conformance.. reports show all kinds of I
trash and foreign objects were inadvertently buried in the concrete va11s of the two reactor build 4ngs and fuel handling buildings."

"These foreign items in the walls ineinde velding cable, polyethylene sheets, chadne,. vibrator heads, pieces of 2-by-4 boards, electric cord, construction hose - about everything, apparently, except an old pair of panty hose."
"The first reports on debris in the concrete pours go back to 1977.
The last was dated J=rnt=g 8,1980. It apparently is a still -
continuing problem."
4.
"A report dated January.6,1978, shows there were also problems at that time with the grout used to plug the voids. Apparently because of improper miring, the grout was below strength, bleeding and shr4nk4ng."
We should review the above items to determine their causes, extent of the problems and corrective actions taken by the licensee.
The following alleged deficiencias have been investigated by Region IV:
"Other defir4 - ies in the reports 4ne1=da no inspection records for 93 l
reinforcing bar Cadwalds in the two reactor hn41 dings, mishand14ng of waterproofing membranes and improperly filled taper tie holes (the ties are used to hold concrete forms in place during pours)."
