RE:

We have recently sent the enclosed letter to Babcock & Wilcox Company regarding the potential for excessive control rod guide tube wear at facilities using the B&W design. This infonnation is required to assess the significance of control rod guide tube wear at your facility.

4 We requested the required infonsation from the vendor, in order to provide us with an overall assessment of this problem and to minimize the amount of utility, vendor and NRC staff work required. However, should this approach to obtain the necessary infomation not be successful, a direct response to the enclosed questions, from each licensee utilizing the B&W design, will be required.

We request your cooperation with B&W in generating and analyzing the control rod guide tube wear data necessary to address this concern.

Sincerely.

Origiset signed n; Steven A.Yarla Domenic B. Yassallo, Assistant Director for Light Water Reactors Division of Project Management
