NUCLEAR FUEL SAFEGUARDS
Nuclear fuel has three
barriers to protect the public:
1. Fuel pellets are sealed in
zirconium tubes2. Fuel assemblies are enclosed
in a steel pressure vessel that
is 8-inches thick
3. Reactor is enclosed in the
concrete containment structurethat is 4-feet thick

� Safety is our highest priority ± three types:
1. Nuclear ±
� Protect the public and our environment
2. Radiological ±
� Limit our employees¶ exposure to radiation
3. Industrial ±� Protect our employees from injury

EMERGENCY PLANNING FOR U.S.
NUCLEAR ENERGY FACILITIES
� 10-mile emergency planning zone (evacuation or sheltering); 50-mile monitoring zone for environment and food.
� Radiation monitoring by plant site, Nuclear Regulatory Commission(NRC) and state and local personnel from the site and surrounding
areas
� Decisions on public precautionary measures made by state or localauthorities based on recommendations from plant operator andNRC
� Emergency plan exercises in coordination with state, local, and
federal officials, evaluated by the NRC and FEMA

INSTITUTE of NUCLEAR POWER OPERATIONS (INPO)
HAS ISSUED IMMEDIATE ACTIONS FOR ALL U.S. NUCLEAR PLANTS
� Consistent with U.S. Nuclear industry principles:
± Nuclear safety undergoes constant examination
± Organizational learning is embraced
� The following actions are being taken:
± Verify the capability to mitigate conditions that result from beyond designbasis events committed to in licensing documents and Severe AccidentManagement Guidelines (SAMGs).
± Verify the capability to mitigate station blackout (SBO) conditions required bystation design is functional and valid.
± Verify the capability to mitigate internal and external flooding eventsrequired by station design.
± Perform walk downs and inspections of important equipment needed tomitigate fire and flood events to identify any potential for equipment functionto be lost during seismic events appropriate for the site.

U.S. NUCLEAR REGULATORY COMMISSION OTED
TO LAUNCH A TWO PRONGED RE IEW OF U.S.
NUCLEAR POWER PLANT SAFETY
� The Commission has created a task force made up of current senior
managers and former NRC experts with relevant experience.
� The task force will conduct a short term and long term analysis of
lessons that can be learned from this event.
� The task force will provide updates on the short term effort in 30, 60,and 90 days.
� The long term review will being no later than 90 days and will
determine if any permanent changes need to be made to NRC
regulations and programs within 6 months.
