4. Identification of Occurrence Fuel assembly 3A33 fell about five feet during transfer from its shipping container to the inspection station. The area was evacuated and the control center was notified. Preliminary radiation surveys did not show radioactive contamination. Extensive radiation and contamination surveys

, showed that there was no release of radioactive material.

5. Conditions Prior to Occurrence The plant is under construction.

This resulted in dropping the fuel assembly and fuel handling tool. The cable was certified to support 2400 lbs. and the assembly weighed 1550 lbs.

, The cause of failure is still under study.

Soms of the fuel pins were bowed, however none of the fuel pins ruptured. Some of the spacer grids were broken. The ?.ower end fitting was bent. Some of welds of the fuel handling tool were cracked.

9. Corrective Action All fuel handling slings will be evaluated and consideration given to elimin-O i
