Dear Sir or Madam:
As requested at the Reference 1 meeting on November 20, 2003, Southern California Edison (SCE) submits this letter of intent to participate in the NRC probabilistic risk assessment pilot program to guide implementation of Regulatory Guide 1.200 For Trial Use, 'An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities," and the associated draft standard review plan, Chapter 19.1, "Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-informed Activities."
The pilot application SCE proposes to submit is a license amendment request (LAR) which will include adding a new Condition to Limiting Condition For Operation 3.8.4, "DC Sources - Operating," allowing manual cross-connect of distribution subsystems with a Completion Time of 30 days. The LAR will include other associated changes necessary to allow on-line maintenance of the Batteries and DC Sources.

Document Control Desk March 17, 2004 The NRC has indicated this review of pilot applications is eligible for a waiver of review fees (Reference 2).
Our current schedule for submitting the LAR is April 2004. Our current plant maintenance schedule would necessitate that we target NRC completion of the LAR within one year; i.e.,
by April 2005.
