I Enclosure B to NRC-06-0016 March 16,2006 Page 2 of 2 Service Life of Main Steam Bypass Lines In accordance with Detroit Edison letter to the NRC dated November 7, 1986 (VP-86-0154), the cumulative time the main steam bypass lines are operated with the bypass valves between 30 percent and 45 percent open will be reported annually. A cumulative value of 100 days is riot to be exceeded without prior NRC notification.
Evaluations performed by Stone and Webster and by Hopper and Associates concluded that the bypass lines are acceptable for safe operation when operated within the 100 day constraint.
Based on these evaluations, the new main steam bypass piping that was installed in 1985 :has a service life that will allow it to function for the life of the plant under anticipated operating conditions. The main steam bypass lines cumulative usage was 40.66 days as of December 31, 2005.

The current license basis Peak Clad Temperature (PCT) for Fermi 2 is 1650 degrees Fahrenheit.
This is a change from the previous reporting period. Fermi 2 re-analyzed the Loss of CoDlant Accident (LOCA) for all fuel currently in the Reactor Pressure Vessel. Two LOCA analyses were performed for General Electric (GE) 11 and GE 14 fuel which also incorporated all error reports. No new error reports have been issued against Fermi 2 since completing the LOCA analysis. There is a 550 degrees Fahrenheit margin to the 2200 degrees Fahrenheit PCT limit given in 10 CFR 50.46.
