ATTORNEY GENERAL'S PROPOSED FINDINGS OF FACT AND CONCLUSIONS OF LAW on Eddleman Contention 57-C-3 (Night-Time Notification) 1.- Eddleman Contention 57-C-3 (Night-time notification) as admitted provides:

The plan does not have provisions for. notification at night, e .g. in the hours between 1 a.m. and

~6- a.m. when most people living near the plant would normally be asleep. Nor does the plan assure that they would be timely awakened to

- take sheltering action, as e .g. on a _ summer night when many might have windows open or air conditioners on. The plan. should provide automatic phone-dialing equipment to transmit an emergency message to all households in the EPZ for Harris, asking people to alert their-phoneless neighbors.

2.- .10 C.F.R. 550.47 (b) (5), the Nuclear Regulatory Commissions' (NRC) emergency planning regulations, provides in pertinent parts-

• • • means to provide early notification

• • • to. the populace within the plume exposure pathway ' Emergency Planning Zone have been established.

10 C.F.R., Part 50, Appendix E, s. IV.D.3. further provides:-

The design objective of the prompt public notification system shall be to have the capability to essentially complete the initial notification of - the public ' within the plume

. exposure pathway EPZ within about 15 minutes.

3. LTo fulfill; these requirements, the Applicant has relied n ,uponithe numerical design' criteria for fixed ' siren systems set forthlin NUREG-0654, discussed - in greater - de tail in FEMA ' 43.

NUREG-0654 ?a'nd FEMA 43 basically provide that the design of an adequate - siren ' system should be 10 dB above average daytime

~

Lambient b'ackground levelst or a min imum of 60 dB.

4. Thel Federal Emergency: Management Agency (FEMA) conducted a ' review of. Applicant's siren = system against NUREG-0654 -and FEMA 4

. 43: numerical criteria and concluded that with the addition of six sirens, Applicants' alarm system. conservatively' meets the NRC/PEMA design criteria, which is based on daytime ambient

- background-levels.-

5.- Both' Applicants. and FEMA have conducted e Laborate s- imathematical estimates of' the sound levels expected by use of Applicants'. siren system.

6 . -- Dr. Reada Bassiouni, an acoustical consultant under contracto to Applicant, challenged the awakening curves on which

'the FEMA analysis relies.

7. 3b party to this docket has actually conducted a controlled field . test owith.' follow-up survey to determine actual performance o f the ' siren system.

8.- 'Dr. Reada Bassiouni's statement of November 5, 1985, made in formally- to the . Board ' and assembled parties via telephone hookup, was made- part of the o f ficial . record by Board ruling of December 4, 1985. Dr. Bassiouni noted that: '

a.. Although CP&L has ' fully met the federal requirements of i -NUREG- 0654 and FEMA '43 for the alert and notification' system, the nighttime notification of Contention 57-C-3 is 'not addressed in the federal guidelines.

I

b. Reliance on an. informal alerting system -- a component Lof the ; Applicant's plan -- is an inferior safety standard.

~

c. A better' alternative than " informal alerting" is . to design a siren system with nighttime alerting as a target.

9.- ' The_ FEMA 43 criteria Lgive no consideration to factors pertinent to nighttime - notification: specifically, to the fact that for .a ' sleeping person in air-conditioned house with closed windows, the probability of arousal from sleep with a siren sound' level' of '60 dB: is essentially zero. With windows open, the t

-  : probability only increases by an incremental 7-8%.--(Tr 9650) 4

+

6 : --

' ~

10. . Testimony indicated .that even to achieve a 50% :

iprobabiltylof arousal .from sleep of an individual in a~ house with the windows. closed required ' outdoor sound levels of 90-99 dB (Tr 19927).

'll.J Per: tho' Harris summer scenario- - assuming ' 36% of the homes in the EPE with windows open -- arouscl is_ estimated at approximately 70%. Assuming, arguendo, the accuracy of _ this

!6 - estimate, the balance of the " prompt notificatior avstem" ,

described-in 10 CFR 50.47 (b) ( 5) ' would of . necessit'y consist o f

~

ancillary notification by l emergency vehicles and by " informal notification," or the " Aunt Minnie phenomenom."

12. The capability of either or- both of these activities to '

Tsupplement - the sirens and " . . . essentially complete 1the initial notification' of the~ public withing the plume exposure pathway EPZ

-within -about 15 minutes" (10 C.F.R. Part 50, Appendix E, IV D.3) appears highly suspect, particularly in a nighttime situation. ,

It 'is clear that the reliability, effectiveness and speed with i

- which these siren-alternatives would operate are unknown, given f the' fact that there have been no actual field-tests.

13. As. this panel of .the Atomic Safety and Licensing Board has' previously' indicated to the Nuclear Regulatory _ Commission on November 19, 1985, " should any deficiencies in nighttime

- notification emerge from the: Shearon Harris record, we could fashion 'e f fective measures - to deal with them on a site - specific basis."

14. We do find deficiencies in nighttime. notification and hereby' conclude. that neither Applicant's plan nor the FEMA 43 criteria give proper asurance of the achievement of a satisfactory level of nighttime alerting. -

15. Our previously manifested view is that actual field testing of a siren system around a nuclear plant between midnight and 6:00 a.m. should be conducted to determine the actual percentage of arousal from sleep of EPZ residents.

16._. WHEREFORE,- it is' hereby ordered that Applicant shall ,

conduct an actual field test of its siren system between midnight )

and-6:00 a.m., shall collect data and cuantify the results '

thereof, and 'shall' report to the Board and all parties on the l percentage arousal from sleep achieved by the system as designed.- Further relief, if.necessary, shall be determined i l

e s.,

af ter all-parties have had an opporturity to comment on the

- results of the field test.

' Respectfully submitted this 16tn day of December, 1985.
