ABSTRACT i

The Safeguards Summary Event List (SSEL), Vol. 2, Rev. 6, provides brief summaries of several hundred safeguards-related events involving nuclear material or facilities regulated by the U.S. Nuclear Regulatory Commission (NRC) which occurred and were reported from Jaruary 1, 1990, through December 31, 1997.

Because of public interest, the Miscellaneous category includes a few events which involve either source material, byproduct material, or natural uranium which are exempt from safeguards requirements.

Events are described under the categories of Bomb-related, Intrusion, Missing and/or Allegedly Stolen, Transportation-related, Tampering / Vandalism, l

Firearms, Radiological Sabotage, Nonradiological Sabotage, and Miscellaneous.

The information contained in the event descriptions is derived primarily from official NRC reporting channels.

Executive Summary i

As m

The Safeguards Summary Event List (SSEL), Vol. 2, Rev. 6, provides brief summaries of several hundred safeguards-related events involving nuclear material or facilities regulated by the U.S. Nuclear Regulatory Commission (NRC) which occurred and were reported from January 1, 1990, through December.31, 1997. Because of public interest, the Miscellaneous category

- includes a few events which involve either_ source material, byproduct i

material, or natural uranium which are exempt from safeguards requirements.

Events are described under the categories of Bomb-related, Intrusion, Missing and/or Allegedly Stolen, Transportation-related, Tampering / vandalism, Firearms, Radiological Sabotage, Nonradiological Sabotage, and Miscellaneous.

1 The information contained in the event descriptions is reported primarily by I

the licensees, NRC resident inspectors or NRC Regional Information Assessment i

Ter.m (IAT) personnel to the NRC Operations Center or the IAT in the Division l

of Fuel Cycle Safety and Safeguards, Office of Nuclear Material Safety and i

Safeguards.

Recent changes to Section 831 of Chapter 39 of Title 18 of the U.S. Code regarding criminal activity includes a significant expansion of the i

Federal Bureau of Investigation's jurisdiction to initiate criminal investigation for the malicious use of nuclear material or nuclear byproduct material. This change could result in increased reporting of these types of incidents.

The document is divided into two major sections: a chronological listing of events by category, and a short statistical analysis. This year the format has been changed to produce a shorter, more useful document.

First, the Arson category has been folded into bomb-related events as there has been only one Arson event in the last ten years.

Second, an executis; summary was added.

Third, the statistical analysis is now limited to the last ten years (1987-1997), as opposed to starting in 1976, as was done in previous reports.

Finally, the events index has been eliminated.

For the third straight year, the overall number of Safeguards Events dropped.

In 1997, there were only 24 events, as opposed to 32 the previous year (Figure 1).

Since the reporting requirements changed in 1995, there has been a dramatic drop-off in the number of incidents. The highest number of incidents last year were in the Miscellaneous category (6), followed by Firearms and Tampering / Vandalism (5 each) (Figure 2).

Reactor Events continue to outpace non-reactor-events by a wide margin (Figures 3 & 4). Over the past ten years,

- Firearms (501), Bomb-related (194), and miscellaneous events (305) dominate the overall number of safeguards events, with the other four categories combined accounting for the 77 remaining incidents (Figure 5).

The number of power reactors remained steady in 1997 (Figure 6), but will likely drop by up to a half-dozen in 1998 due to plant decommissionings.

8 The most serious incident occurred on August 22, 1997, when it was l

discovered that an individual responsible for killing four persons in New l

Hampshire before being killed in a police shoot-out was a contractor with l

unescorted access at Vermont Yankee, Pilgrim, and Indian Point 3 while they L

were in an outage status.

Furthermore, numerous incendiary devices were l

Investigation by 4

NRC and law enforcement revealed no indications that the subject had any malevolent intent towards any of the facilities to which he had access.

s There were several notable incidents of tampering.

For example, on December 1, 1997, cuts in the door seals were found during leak testing of a containment door at McGuire Nuclear Power Plant.

On December 4,

1997, additional cuts were found in the seals. The perpetrator (s) were not apprehended. On October 17, 1997, 11 of 14 instrument cables were discovered damaged in a Sequoyah Unit 2 containment electrical penetration which was being replaced. Preliminary investigation results indicated the cables were deliberately cut and that none of the wires had any safety significance.

\\v INTRODUCTION The Safeguards Summary Event List (SSEL) provides brief summaries of several hundred safeguards-related events involving nuclear materials or facilities regulated by the U.S. Nuclear Regulatory Commission (NRC).. The SSEL is

{

comprised of two parts. Vol.

1, issued July 1992, summarizes events that occurred and were reported from pre-NRC through December 31, 1989.

Vol. 2, Rev. 6, issued July 1998, summarizes events that occurred January 1,

1990, through December 31, 1997.

Because of public interest, the Miscellaneous category includes a few events which involve either byproduct material, source material, or natural uranium which are exempt from safeguards requirements.

As the list is intended to provide a broad perspective on the nature of safeguards incidents in the licensed nuclear industry, both unusual and routine events are described.

Eventa have been placed in the several categories described below.

Each listing is included in a single category unless it is transportation-related, in which case it is cross-referenced in the Transportation category.

Bomb-Relatedt Events concerned with explosives, incendiary devices or arson.

Section A Events in which a bomb or explosive material was located l

or an explosion occurred at a licensed facility.

/%

section Br All other bomb-related events (e.g., hoax bomb threats).

k II.

Intrusion:

Incidents of attempted or actual penetration of a facility's barriers or safeguards systems.

III. Missina or Alleaedly stolen:

Events in which safeguarded material was stolen, alleged to be stolen, discovered missing, or found.

IV. Trannportation-Relatedt Events typically include incidents where safeguarded material was misrouted or involved in an accident.

Material reported missing or stolen during transport, for example, would be included in Category III and cross-referenced in the Transportation category.

V.

Tamnerina/Vandalisme Incidents of destruction or attempted j

destruction of property, parts, and equipment which do not directly cause a radioactive release.

1 VI. Arson: These events have been moved to Category I effective this report.

VII. Firearms-Relatedt Events typically describe the discharge, discovery, or loss of firearms at a licensed facility.

an unauthorized vehicle drove through the open, but manned, north gate in the owner-controlled area, drove through the parking lot to the protected area, crashed through a gate in the protected area fence, smashed into the turbine building roll-up doors, and eventually came to a halt approximately 63 feet inside i

the turbine building. The driver exited the vehicle and fled; his whereabouts were not innediately known.

Action:

Immediately after the intruder passed through the north gate, security notified the central alarm station who, in turn, notified the control room.

Designated vital areas were secured with armed personnel and vital access restricted via key cards. A security emergency was declared at 6:55 a.m., a site area emergency was declared at 7:05 a.m.,

and appropriate notifications were made. At 7:20 a.m.,

the Pennsylvania State Police arrived on site. At 8:38 a.m.,

the first search and clear operation began in the turbine building with negative results. At 9 a.m.,

the U.S. Army 56th Explosive Ordinance Team initiated a check of the vehicle for explosives with negative results. At 10:57 a.m.,

during the conduct of the second turbine building search and clear operation,

.the intruder was found underneath circulating water piping on the I

bottom floor of the turbine building and apprehended by site security. He was released to the Pennsylvania State Police, ummelution: Augmented security measures-have been implemented by the licensee.

In addition, because of this event and the February 1993 bombing of the world Trade center, the Nuclear Regulatory Commission decided to revise the design basis threat for radiological sabotage, 10 CPR 73.1, to include. land-based vehicles against which nuclear power plant licensees would develop protection systems.
