EMERGENCY PLANNING

,i 1'

In the wake of the March 1979 accidentiat TMI-2, the NRC ' undertook a fonnal. . . .

i l

reconsideration of the role of emergency planning in ensuring the continued; i

protection of the public health and' safety in areas around nuclear. power . )

i The Commission., issued regulations requiring, prior to the issuence of a plants. 5 i

an operating license, a finding of " reasonable assurance'that adequate p,cotective measures can and will be taken in the 2svent of a radiological-emergency". The regulations set forth 16' emergency planning standards and l

define the areas of responsibility of the licensee and state and local )

organizat{ons concerned with emergency responses. l A key feature of the regulations is the. Emergency Planning Zone (EPZ)= concept.. 1 1

which has been adopted as an added conservatism to the'NRC's " defense'in -)

I depth" safety philosophy. Briefly stated, this' philosophy: .(1) requires high 1 quality in the design, construction and operation of nuclear plants to reduce the likelihood of malfunctions in the first instance; (2) recognizes that equipment can fail and operators can make mistakes, therefore requiring safety -

.l systems to reduce the chances that malfunctions will lead to accidents that '

release fission products from the fuel; and (3) recognizes that, in spite of these precautions, serious fuel damage. accidents can happen, therefore requiring containment structures and other safety features to prevent the ~

The'added feature of- emergency planning release of fission products offsite.

~Z= - i to the defense in depth philosophy provides that, even in the un11kely event 1

of an offsite fission product release, there is reasonable assurance that ll

~

emergency protective actions can be taken to protect the population around s nuclear power plants. The Commission,;in order to bound the range of possible q

accident consequences, adopted a ten mile ~ radius around a plant sita as the i EPZ.

1 The overall objective of amargency response plans is'to provide a range of l protective actions- that could be taken to provide dose savings to the popu- i lation within the EPZ for a spectrum of acefdents. It is'not the ob.jective~of emergency planning to assure evacuation of the EPZ in all possible accidents.'

For example, in a rapidly evolving accident with early offsite release,- -

sheltering of the population within the EPZ during the passage of the radio- 1 active plume (or cloud-like release) would provide a greater dose savings to the public than attempting to evacuate. After passage of-the plume,- .

~

evacuation may be appropriate to protect the public from cont 1nued exposure.to I

the ground dose from radioactive particulate material deposited from the. plume.

ll l* With respect to the adequacy of emergency plans, the standard of reasonable j assurance requires the NRC staff to make a predictive finding that there are no 4 l

undue risks to the public health and safety. It does not require a finding of i zero risk. In particular, the standard of reasonable assurance does not require an absolute demonstration thatithe population within the EPZ can be'  !

i where sheltering rather than evacuation would be the appropriate protective .

action because evacuattan could involve greater risk to the public than j exposure to low levels of radiation. Therefore, what constitutes reasonable assurance in the area of emergency planning is a finding that adequate i emergency plans are in place to' permiti a range of protective actions as l 1

dictated by conditions, that there are adequate staff and facilities to imple- .!

ment the plans and that the plans have been found to be workable in 'an i

emergency exercise, 1
