,

on July 21, 1978. The investigation involved 114 investigative-hours by an NRC

l regional based investigator and a regional based inspector.

Resul ts: The noise and earth tremor which formed the basis of a complaint about

I BACXGROUND

A. Reason for Investigation

During the period from July 26 to July 31, 1978, the Nuclear Re-

gulatory Commission (NRC, Region I) received several telephone

calls from members of the public who reside in the vicinity of the

Seabrook Station site. In each case, the individuals stated that

blasting was continuing on the site even though the construction

permits for the Seabrook Units i and 2 were suspended effective ,

6:00 p.m.-(EDT) on July 21, 1978.

!

,

An investigation regarding these complaints was initiated by the

NRC, Region ILon July 26, 1978.

B. Order of the Nuclear Regulatory Commission ,

By Order of the NRC on June 30, 1978, the construction permits for

the Seabrook Station, Units 1 and 2, were suspended effective 6:00

p.m. (EDT) on July 21, 1978.

The Order permitted, "only such actions as are necessary to protect

the environmental integrity of the site or to protect buildings,

material or personnel at the site."

C. Identification of Involved Organizations

II SUMMARY OF FINDINGS

A. Complaints and Investigation Findings

The following complaints were obtained by telephone calls to the

Region I office and also during interviews of individuals in and

effective 6:00 p.m. (EDT) on July 21, 1978.

1. Complaint No. 1

That blasting was continuing on the site after July 21, 1978.

The NRC investigation found no information or evidence that

any explosives were used on the site during the period from

6:00 p.m. on July 21, 1978 through August 5,1978, which was

the end of the onsite portion of this investigation.

2. Complaint No. 2

That construction activities at the site had not ceased, for

the following reasons:

-- Large numbers of people entering and leaving the site on

all shifts.

-- Tower cranes in different orientations from one day to

the next.

--

Motors roaring throughout the night.

--

Sounds of trucks dumping large rocks.

--

Dump truck tailgates slamming.

-- Trees being cut down.

III DETAILS

A. Introduction-

Pursuant to the Nuclear Regulatory Commission Order on June 30,

1978, the Seabrook Station Units 1 and 2 construction permits were

suspended effective 6:00 p.m. (EDT) on July 21, 1978.

An inspection lwas conducted by a NRC Region I representative on

July 21-27, 1978. The purpose of this inspection was to insure, by

observation, interviews, and examination of applicable records,

that the NRC Order to halt construction had been fully and correctly

implemented.

This investigation was initiated as a result of the NRC receiving

telephone complaints that blasting and construction activities had

not ceased as of July 21, 1978.

B. Scope of Investigation

This investigation included an examination of pertinent documents

and records, interviews and contacts with individuals having signi-

ficant information, and observations by the investigators while at

the Seabrook Station Unit 1 and 2 sites. It also included interviews

and contacts with the complainants, individual members of the

public, Pease Air Force Base and the Federal Aviation Administration.

The scope of this investigation was limited to those complaints

relating to the suspension of the construction permits.

There was general agreement that the reports from 8:20 to 8:30 AM; at

9:50 AM; and, from 3:00 to 3:30 PM were louder than others and created

more vibration.

During a discussion at one residence, at about 9:55 a.m.

on August 3,1978, the investigators and all present

heard a sound and felt a tremor similar to others that

those present had previously reported. An immediate

telephone call to neighbors confirmed that they had heard

and felt it also. No other similar sounds were heard by

the investigators while in the Seabrook, New Hampshire

area during the period from August 2 through August 5,

1978.

During an inspection conducted at the Seabrook, construc-

tion site, the investigators examined blasting areas,

explosives magazines (all found to,be empty), photographed

dump area for blasted rock from ground level and also

aerial to provide a method of comparing change, inter-

viewed blasting personnel, and examined blasting records

and explosive material accounting records. The documenta-

tion provided to the investigators indicated that the

final explosive charge which was detonated prior to the

suspension orders occurred on July 21,1978 at 11:48 a.m.

in the Unit 1 foundation. Documentation also confirmed

that all explosive materials were removed from the site

on July 25, 1978. This information was also confirmed by

discussions with the involved individuals.

The investigators contacted the Pease Air Force Base,

Portsmouth, New Hamphsire, and were informed that no

similar complaints of sounds had been received at that

location.

The investigators contacted the Federal Aviation Admin-

istration (FAA), Burlington, Massachusetts and were in-

formed that they had received reports from citizens in

the Boston North Shore Area and southern New Hampshire of

sounds similar to those reported to the NRC.

(c) NRC Findings

The NRC investigation found no information or evidence  ;

that any explosives were used on the site during the j

period from 6:00 p.m. on July 21, 1973, through August 5, !

1978, which was the end of the onsite portion of this j

investigation.

During this investigation, all plant areas were examined

for evidence of unauthorized work being performed. Areas

examined included the offshore jackup barge, onshore

tunnel shaft area, reactor building excavations, cooling

water pumphouse excavation, concrete and ironwork, con-

crete batch plant, settling basins, storage buildings,

rock dumps, maintenance and testing shops, laydown areas,

office areas, and the Educational Center area.

The investigators observed authorized activities of an

environmental nature in progress, which included ditching

and seeding work on the borders of the new plant access

road, planting and seeding adjacent to the Educational

Center, watering-down of dusty roads and parking areas,

and removal of water from some low elevations by pumping.

Equipment was also observed being loaded onto trucks for

removal from the site.

The investigators determined that the total work force at

the site on July 21, 1978 had been reduced by 62 percent

as of August 2,1978. There were individuals assigned on

all shifts with the majority being on day shift. On

August 2, 1978, supervision and office workers accounted

i for 75 percent of the total work force.

l The investigators found that tower cranes did change in

orientation which was a normal condition since they are

free to turn in the wind when not in use. The other

reported complaints were correlated with activities on

site and none were found related to site activities which

were not permissible.

In addition to direct observation of the site, the in-

vestigators took ground and aerial photographs to provide

a method of comparing change.

(c) NRC Findings

The NRC investigation found that the Order of the Nuclear

Regulatory Comission which suspended the construction

permits was being complied with and that only those

actions permitted by the Order were being performed.

On July 26, 1978, the investigator discussed the reason for the

t investigation with Mr. J. H. Herrin, Site Manager.

On August 8, 1978, during a telephone discussion with Mr. Herrin,

the investigator discussed the investigation findings and informed

the licensee that no items of noncompliance had been identified.
