Dear fir. Standerfer:
Subject:
Ilydraulic Impact Chisel 4
i'
Reference:
Letter 4410-86-L-0021, F. Standerfer to W. Travers, Hydraulic Impact Chisel, dated January 22, 1985 The referenced letter forwarded for NRC staff concurrence, GPU flucicar's proposal to use a hydraulic impact chisel to separate fused structural
^
material and perform other sizing operations in the reactor vessel. The hydraulically operated chisel can impart M00 impacts per minute with an energy of about 10 foot-pnunds, and will be supported by olther a long handled tool or the manual tool positioner.
The staff concurs with your assessment that the safety consequences of the use 3
of the tool are bounded by the previously approved Early Defueling Safety Evaluation Report and that the use of the tool does not constitute an P
unreviewed safety question.
L. )
We therefore approve the use of the proposed hydraulic impact chisel contingent upon submittal of the related procedures subject to our approval por Technical Specification 6.8.2.
Sincerely, omostAL sooNED OFs Wii!ic 1 D. Travers e
