- 9. Why has not the NRC demanded that the modifications be.made and the deadline he met regarding the modifications required by the NRC as an urgency measure 10 yoars ago as a result of.the Three Mile Island accident?
- 10. Why hasn't Edison been required (under the.TMI Action Plan) to' complete the contrcl room design review or the safety Parameter Display System for San Onofre 1?
11.. San onofra 1 has also not been required to install pro i
instrumentation to detect inadequate reactor core cooling,per has NRC_ demanded that Edison complete testing and analysis for nor 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 escapa deadlines for San onofra's revisions in its accident prevention and response procedures plan. Why?
- 14. Why hasn't the NRC required Edison to complete the facility that is necessary to effectively implement emergency planning and evacuation procedures (the Emergency operations Center)?
I look forward to receiving your answers to each of the questions.
Sincerely,
