Description of Particular Event or Circumstance:
When the operator started the recirculation pump for the
"A" floor drain sample tank, at about 8:00 a.m., December 6, 1972, he noted
.a slight decrease in tank level.
He immediately went to the sample tank area (which is outside the radwaste building) and obs,crved water i
spraying against the building and running down into the curbed area l
around the tanks, and spraying on the sidewalk outside the curbing.
.He immediately went back inside,and stopped the pump. A tank inven-tory showed that 50 gallons of water was lost from the tank. An inspection in the area showed that the drain line inside the curbing was valved to go to the discharge canal rather than to return to the l
radwaste building. 'As a result, only approximately 1 gallon of water
'
was recovered.

Action by Licensee:
1.
A sample of water was obtained from the tank and was analyzed, with the following results:
Isotopes Activity (uCi/cc)
Ratio (Ac tivitv/MPC)
Gross Activity 2.05 x 10-2
_
Cobolt-60 5.89 x 10-3 117.8 Cesium-144 4.08 x 10-3 453.3 g-3 Cesium-137 5.99 x 10 299.5-3 Manganese-54 3.55 x 10 35.5

was located just outside of the building between the building and the tank. This pipe is 3" carbon steel pipe and was re-
.
paired by welding a patch over the failed area. According to the maintenance foreman, he has ordered stainless steel pipe to replace this line and the comparable line to the "B" floor
drain sample tank.
,
3.
The water that landed on the sidewalk outside of the curb was
soaked up with a blotter, however, before the area was sur-
'i veyed for contamination, it started raining..The sidewalk was not smeared for contamination until Deceinber 7,1972. At that time, the sidewalk was clear of contamination, however, the area inside the curb was contaminated up to 5000 cpm. The
sand next to the sidewalk was also contaminated. The upper
,
layer of sand was removed with the contamination. The licensee
.
issued instructions for the drain from the curbed area'to be either valved closed, or to the radwaste building sumps.
.'4. 'The licensee plans to survey other equipment to determine the
' potential for this type of corrosion-errosion failure as part
,
of his general study of the operation of the radwaste facility.
,
5.
The licensee will submit a written report to the Directorate of Licensing within 10 days as required by the Technical Specifica-
tions.
