LIMITING CONDITION FOR OPERATION SURVEILLANCE REQUIRENENT

10. Repaired Tube means a tube that has undemone a process that re-establishes its serviceability.

The sleeving process utilized shall be one of the following:

a.

The Combustion Engineering welded sleeve process as descri M in Report CEM-331-P, Revision 1-P.**

b.

The Westinghouse Electric Corporation mechanical sleeve process as described in Report WCAP-Il669.

c.

The Bechtel-KWU Alliance welded sleeve process as described in Report BKAT-01-P, Revision 1.

11. F* Distance is the length of undgraded tube required to resist pullout. This distance is i

measured from the bottom of the upper hard roll transition toward the bottom of the tubesheet and has been conservatively determined to be 1.05 inches. The determination of the F*

Distance is satisfied by the mechanical tool (rolling pin) used to install the joint having an effective length of greater than or equal to 1.05 inches. The F* Distance is applicable only to tubes that are rerolled below the mid-plane of the tubesheet and have no degradation in the rerolled expansion joints.

12. F* Tube is a tube with indications below the F*

Distance, equal to or grpater than 40%, and no indications within the F Distance.

• • The following sections of AB8/CE Report CEN-629-P Revision 00 shall be implemented in conjunction with Report CEN-331-P, Revision 1-P:

Section 4.5.3 - Tube Brushing-Cleaning Equipment Section 4.5.7 - Nondestructive Examination Section 5.0

- Sleeve Examination Program Section 9.3.1 - Cleaning Qualification i

t 74f3 Amendment Nos. 174 and 161 t

8:s:s:

3.3.1 Steam Generators 4.3.1 The F* Distance will be controlled by process control. For a new additional roll expansion, the requirement will be at least 1.05 inches of new hard roll. This is controlled by the length of the rolling pin used during the mechanical installation of the new hard roll joint. The distance from the original roll transition zone is also controlled by the process in that the lower end of the new roll expansion is located approximately one inch above the original factory hard roll expansion.

In the case of the new roll, eddy current examination will confirm that there are no indications in the new roll regior and that there is a new roll region with well defined upper and lower expansion transitions. The F* Distance is not applicable to the original factory hard roll.
