9. Why has not the NRC demanded that the modifications be made and the deadline be met regarding the modifications required by the NRC as an urgency measure 10 yoars ago as a result of the Three Mile Island accident? ,

,J

10. Why hasn't Edison been required (under the TMI Action Plan) to complete the control room design review or the Safety Parameter Display System for San Onofre 1?

11.

San Onofre 1 has also not been required to install proper instrumentation to detect inadequate reactor core cooling, nor has NRC demanded that Edison complete testing and analysis for several safety-related valves and pipes associated with cooling.

Why?

12. How can it be assumed that this reactor can operate safely with a damaged thermal heat shield since Edison has not yet installed the proper equipment to facilitate monitoring of adequate reactor core cooling?
13. NRC has allowed Edison to escape deadlines for San Onofre's revisions plan. Why?

in its accident prevention and response procedures 14.

I that Why hasn't thetoNRC is necessary required effectively Edison to complete the f acility implement emergency planning and evacuation procedures l

(the Emergency operations center)?

' I look fotward to receiving your answers to each of the questions.

Sincerely, e
