Response to Generic Letter 94-02, "Long Term Solutions and Upgrade of interim Operating Recommendations For Thermal Hydraulic Instabilities in Boiling Water Reactors" Gentlemen:
In a letter from PECO Energy Company (PECO Energy) to the U. S. Nuclear Regulatory Commission (USNRC) dated September 9,1994, PECO Energy provided our response to Generic Letter (GL) 94-02, "Long Term Solutions and Upgrade of interim Operating Recommendations For Thermal Hydraulic instabilities in Boiling Water Reactors." in the letter, PECO Energy proposed a schedule for implementation of the Enhanced Option 1-A Stability Solution at
' Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3. The schedule was based on preliminary information received from the Boiling Water Reactor Owners' Group (BWROG) and contingent upon USNRC approval of the i
BWROG methodology (NEDO-32339, " Reactor Stability Long Term Solution:
Enhanced Option 1-A").
Due to significant hardware delays (i.e., Period Based Detection System (PBDS)'
- and Flow Control Trip Reference (FCTR) cards), it is necessary to revise the schedule for submittog the associated License Change Application (LCA) to the USNRC and for. implementing the Enhanced Option I-A Stability Solution at PBAPS, Units 2 and 3, as follows:

}
- Submit LCA 1 O98 3 0/98
- Implement Solution I-A 3098 1 0/99 The proposed deferral dates for implementation of the solution is based on: 1) hardware delivery delays (i.e., the PBDS and FCTR cards); 2) time needed to perform the Limerick installation and to incorporate lessons learned into the Peach Bottom design and installation package, and; 3) time needed to i
accumulate operational experience before final implementation. We anticipate a i
USNRC review period of six months following the LCA submittal.
I If you have any questions, please do not hesitate to contact us.
