NUCLEAR REGULATORY COMMISSION

OFFICE OF NUCLEAR REACTOR REGULATION

WASHINGTON, D.C. 20555-0001 April 2, 1996 NRC INFORMATION NOTICE 96-19: FAILURE OF TONE ALERT RADIOS TO ACTIVATE WHEN

RECEIVING A SHORTENED ACTIVATION SIGNAL

Addressees

All holders of operating licenses or construction permits for nuclear power

reactors.

Purgose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information

notice to alert addressees to the possibility that tone alert radios may not

reliably activate when receiving a shortened activation signal. It is

expected that recipients will review the information for applicability to

their facilities and consider actions, as appropriate, to avoid similar

problems. However, suggestions contained in this information notice are not

NRC requirements; therefore, no specific action or written response is

required.

Description of Circumstances

In a report made pursuant to Section 50.72(b)(1)(v) of Title 10 of the Code o

Federal Regulations (10 CFR 50.72(b)(1)(v)), Event Number 29907, dated

January 30, 1996, the licensee for the Callaway site reported a problem with

tone alert radios. During a test of the Emergency Alert System (EAS), a radio

station engineer observed that a tone alert radio receiver did not activate.

An investigation by the licensee found that the length of the broadcast

activation signal was insufficient to reliably activate the tone alert radio

receiver model in use at the radio station. The broadcast duration of the

activation signal had been reduced from 20 seconds to 8 seconds as permitted

by current Federal Communications Commission (FCC) regulations. The radio

station restored the duration of the activation signal broadcast to the

original 20-second length and observed that the tone alert radio receiver

activated as expected.

Discussion

Section 50.47(b)(5) of 10 CFR requires emergency response plans for nuclear

power reactors to include a means of providing early notification and clear

instruction to the populace within the plume exposure pathway emergency

planning zone (EPZ) in the event of an emergency. Many nuclear power reactor

sites have integrated tone alert radios into alert and notification systems

used to notify and provide instructions to members of the general public near

the site during emergency situations.

-2 IN 96-19 April 2, 1996 These radios may serve as supplements to a siren system by filling in voids in

siren coverage, or they can be the principal means of notifying the EPZ

population. Tone alert radio receivers are used in conjunction with the EAS.

On December 28, 1994, the FCC issued a Report and Order (59 FR 67090)

concerning the Emergency Broadcast System (EBS). This Report and Order

replaced the EBS with what is now known as the EAS. This change allowed for

the creation of a new generation of alerting equipment embracing digital

technology. The change also modified some of the old EBS requirements. One

of the changes permits the use of a shorter duration tone activation signal to

activate tone alert radio receivers. This change may have decreased the

reliability of some tone alert radios currently in use to activate when

required.

Before July 1, 1995, the broadcast duration of the signal that activates tone

alert radios was required to be between 20 and 25 seconds. After July 1,

1995, the broadcast duration of the signal that activates tone alert radios

was permitted to be between 8 and 25 seconds. The FCC encourages the use of

the longer (up to 25 seconds) tone during emergencies.

Tone alert radio receivers are, and have been, available from various

manufacturers for several years. Depending on the specifications provided by

the purchaser, the threshold for activation has been built into receivers.

The signal duration needed for some tone alert radio receiver models may be

longer than the currently approved 8-second minimum signal duration now

allowed by FCC regulations.

The FCC regulations permit individual radio stations to select the duration of

the activation signal they broadcast, provided it is within the limits of 8 to

25 seconds. To reliably activate a tone alert radio receiver the duration of

the activation signal broadcast by the radio station must be long enough to

meet the activation threshold built into tone alert radio receivers in service

in a particular reception area. If the duration of the activation signal

broadcast is not compatible with the threshold set in a receiver, the

reliability of the receiver response is questionable. Either the duration of

the activation signal broadcast or the threshold for activation built into

receivers may need to be modified to ensure compatibility.
