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.
l An inspection was 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 NR.
<
\\
l The FAA has installed a sound monitoring device in Cambridge and is continuing an evaluation to determine the cause of the sound.

(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.
