2. Background

On August 7, 1979 the NRC issued IE Bulletin 79-18 alerting

all operating plants of a potential safety hazard for workers

who may be working in areas where the noise Jevel is too great

to hear audible emergency alarms. The bulletin requested all

licensees to perform studies of their working environment to

determine if any such areas existed, and, if so, to devise

means for ensuring that workers in those areas are also

alerted. Since the bulletin applied only to operating plants,

units under construction were provided with a copy of the

bulletin for information only. Unit 1 of the San Onofre

Nuclear Generating Station (SONGS) was in operation at that

time, but Units 2 and 3 were still under construction.

Southern California Edison (SCE) addressed the bulletin's

items promptly and eventually installed flashing strobe lights

in Unit 1. Plans were made to install similar strobe lights

in Units 2 and 3. In the interim, SCE relied on an

administrative search and rescue system to evacuate workers

who may not hear the audible warnings in Units 2 and 3.

3. Unresolved Item

This inspection was conducted to address Unresolved Item No.

86-01-03 reported in Inspection Report Nos. 50-206/86-01,

50-361/86-01 and 50-362/86-01 which covered an inspection

conducted January 6-10 and February 3-7, 1986. The Unresolved

Item consisted of two main areas of concern regarding SCE's

work to complete the installation of visual alarms in certain

high noise areas in Units 2 and 3:

a) that work to complete the installation may have been

needlessly subjected to considerable delays and that the

licensee may not have adequately tracked progress in the

work activities

b) that, after the installation, workers may not have

been informed of the meaning of the devices nor

instructed in their proper responses.

4. Scope

The inspector interviewed personnel responsible for the

installation of the systems as well as personnel responsible

for tracking this work. The history of events prior to and

after the issuance of Documents PFC 2/3-83-904 and 2/3-83-905

(the supporting documents for the installation of strobe

lights in Units 2 and 3, respectively), was reviewed, along

with documents relating to the tracking of the work from its

early stages to the present. Personnel responsible for

emergency preparedness training were also interviewed and

training documents examined to determine what training, if

any, workers had received after the implementation of the

visible strobe light warning system in Unit 2.

5. Findings

a. Work Delays and Tracking Concerns

The review of pertinent documents provided the following

chronology relative to the implementation of the visual

alarm systems:

1/31/86 SCE issued first bulletin to employees to

inform them of the strobe lights in Unit 2

and what to do in response to their acti- ,

vation (Emergency Planning Bulletin 4-86)

During this inspection the licensee provided documents to

show the tracking and progress of th.ese projects to date.

Based on the interviews and documents examined, there

appears to have been no significant delays in completion

of the prescribed work and SCE has maintained an adequate

tracking of the events of this task. This item of

concern is resolved.

b.- Instruction To Workers Concern

The visual evacuation alarm system had been completely

installed an'd placed in service'in Unit'2 on 3/12/85. .At

the time of this inspection three.of a total of 19 strobe

lights had been installed in Unit 3. The inspector

determined that.no form.of instruction or information had

been provided to workersLregarding the purpose of-the

Unit 2 visual alarm system and their response to its.

activation from the. implementation date of 3/12/85 until

January 31, 1986. ~

! 4 The licensee' agreed.that'no instruction or information

,

-

.had been provided to' workers'regarding the purpose and-

'

function of the' strobe lights until after it had been

discussed during the January 1986 routine emergency

~

l.

preparedness inspection.: However..the licensee 1 contended

that the project was not_completedfsince onlyLUnit'2

strobe lights were cinstalled, with Unit 3 installation-

scheduled for completion during'the next planned outage

in December 1986.' '

,

It.is the licensee's policy that applicable proce'ures d or

instructions are to be implemented only upon completion

- and final acceptance of all; work. They maintained that

i this minimizes confusion regarding system operation on

j thefpart of site personnel. Further, the licensee held

that they presently do not rely on this visual alarm

4 . system to evacuate personnel from.high noise areas, but. '

,

1 . _ - rely on their administrative accountability,andusearch

l system. Therefore, they concluded that' informing workers

!. of the Unit 2 strobe ~11ghts' purpose and the proper

{ response to their activation is not necessary, or

3 required,uat this time.

While the licensee's actions to provide these warning

,

devices for their employees is exemplary, the issue of

concern is whether the employees knew the purpose and how ,

,

to respond to those devices hadschey been activated. It

i was noted that when'the strobe lights were installed in'

1 Unit 2, they were designed to, and do, activate simul-

taneously with the Thunderbolt' Siren system. The

j operators had no option whether to omit the strobe light ,

j signals or not. Thus, the lights would have flashed-

3

automatically anytime the siren system was activated.

j Even if the licensee's expected; response was for,their

i workers to ignore the strobe lights because other *

i evacuation methods were in-use,: proper ins'tructio'n to

this effect would eliminate unnecessary, confusion. j

f

The regulations are clear,that the worker has a right to

j be kept~ informed as to the purposes and functions of

'

protective devices and that the. employer.has"an obli-

gation to' provide that information
10-CFR'19.12 states,

in part that' "All individuals working in6or frequenting

,

i any portion.of~a:restridted~ area.shall beekept informed- ,

of...the purposes'and function's of prot'ective; devices

j; . employed;...shall'be instructed in the appropriate

' response to warnings made ..."

One violation of'NRC requirementsy failure toJprovide ,

j- instructions. required byfl0 CFR 19.12, was~-identified

- (86-01-03). -
