12/31/86 O 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). 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. Events 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 section. The first category, Bomb-Related events, is concerned with explosives or incendiary devices and related threats. This category has been divided into two sections. Section A contains those events in which a bomb or explosive material was located or an explosion occurred at a licensed facility. Section B contains a chronology of all other bomb related (e.g., hoax bomb threat) events. Intrusion Events (the second category) includes incidents of attempted or actual penetration of a facility's barriers or safeguards systems. The Missing or Allegedly Stolen section (the third category) includes events in which licensed material was stolen, alleged to be stolen, or found missing. Category IV, Transportation-Related Events, typically includes incidents where licensed 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. Tampering / Vandalism (the fifth category) includes destruction or attempted destruction of property, parts and equipment which do not directly cause a radioactive release. ( Category VI, Arson, includes intentional acts involving incendiary materials resulting in damage to property, equipment or other assets. The seventh category, Firearms-Related Events, typically describes the discharge, discovery, or loss of firearms at a licensed facility. Radiological Sabotage, Category VIIIA, includes any deliberate act directed against a licensed activity which could endanger the public health and safety by exposure to radiation. Nonradiological Sabotage, Category VIIIB, includes events characterized by the FBI as sabotage but which could not endanger the public health and safety by exposure to radiation. Finally, Miscellaneous Events are those which hold some interest to safeguards but which do not fit into any of the previously described categories. Each event listed in the body of the report is identified by an alphanumeric code composed of the appropriate category roman numeral, the last two digits of the year in which the event occurred, and a sequential number for that specific year and category. Each incident listing includes the appropriate date and location and a brief description of the event. Descriptions vary in detail according to the amount of data available through NRC reporting channels. vii

If the source had been extricated by force, the radiation level from the unshielded source at 100 centimeters would have been only 0.1 mr/hr., which would not have posed a significant health hazard. Mississippi authorities agreed to alert the operator of a nearby landfill and area scrap dealers (about eight) in a 30-mile radius, about the missing gauge. On October 9, 1986, State of Mississippi authorities informed Region II that the guage had been found and had been returned to the Department of Agriculture. O

As a matter of policy, Florida Steel routinely monitored both incoming and outgoing products for radioactivity. In conjunction with the state, Florida Steel determined that the radioactivity was emanating from a small piece of metal. The  ! state took possession of this metal and analyzed it. Prelimin-ary results indicated that the object appeared to be a strontium / yttrium beta-emitting source. A radiation level of 800 millirem per hour was measured on contact with the source. The state amended Florida Steel's license to permit possession of this material.

Vermont Yankee O(~ ) V-86-01 01/09/86 Vermont Yankee Nuclear Power Co. Windham County, VT At 2:40 p.m., the fire protection deluge system for the auxiliary transformer was manually actuated by an unknown person at a local fire box. No fire existed. No damage to the plant resulted. The licensee concluded that the deluge system actuation was an intentional act of tampering or harassment. The reactor had been defueled for an extended piping replacement outage, and station power was being provided by the startup transformers. The licen-see's primary contractor for the recirculation pipe replacement outage had taken a job action against 49 welders within the 24-hour period before the incident. However, no direct connec-tion between these two events was established. None of the affected welders were onsite at the time of the actuation. No  ! perpetrator identified.

In the reactor containment building, one piece of tubing had been cut and sections of the instrumentation tubing had been removed. A third case was found in the safeguards building by instrumen-tation workmen who noticed a suspicious-looking fitting, and on closer examination, determined that the pressure-fitting ferrel had been removed, and the nuts had been retightened to hide the missing ferrel. Licensee investigated, with negative results. Plant status: Preoperational. Fuel present at site. V-86-04 04/23/86 Palo Verde Arizona Public Service Co. Maricopa County, AZ At 5:30 p.m. , a contractor electrician verifying a jumper instal-lation identified a cut wire in an engineered safety features relay cabinet in the outer periphery of the Unit 3 control room. Unit 3 was in the early phase of preoperational testing, and the cabinet was not energized. The wire was safety-related (asso-ciated with containment isolation valve on a steam generator sample line). The licensee investigated the incident and could not determine whether the wire was cut deliberately or acciden-tally during construction activities, such as wire termination or wire strapping. Further investigation of the severed ends under an electron microscope indicated that the wire, one of several within a bundle, had likely been accidently cut by a construction worker as he was removing the tie strap which held the bundle together. Plant status: Unit 1 and 2, Operational; Unit 3, Preoperational. Fuel not present at site for Unit 3. V-86-05 06/19-30/85 Palo Verde Arizona Public Service Co. Maricopa County, AZ At 2:00 p.m., on June 19, 1986, instruments and control technicians performing initial system checks of the Unit 3 Fire Detection System discovered that the internal wiring for at least one of the 18 panels had been modified, causing approximately $3,000 -

                 $5,000 damage to the internal components. Investigation determined         t that person (s) unknown had used two jumper wires to supply the panel with 120-volt AC power. Upon initial energizing of the               !

panel, several 24-volt DC components overheated, causing the i internal damage. O

('j} position. When red-tagged, the switches were independently verified to be in the "off" position. The licensee was unaware of any work activity that would account for the switches being mispositioned. The licensee's check of the remaining tags for the Division 1 0.G. and a check of tags for the Division 2 D.G. found no other discrepancies. A licensee investigation was not conclusive. The mispositioned switches would have been discovered before fuel load and operation, through their normal red tag removal procedures. Plant status: Preoperational. Fuel present at site. V-86-07 10/17/86 Peach Bottom Philadelphia Electric Company York County, PA At about 4:00 p.m., the licensee determined that a terminal strip in the motor control center for one of two standby liquid control pumps had been disengaged. The terminal strip provided control power indication to the control room console only; it had no effect on the operability of the pump. Control room personnel verified the status of emergency systems by examining control room indicators. No discrepancies were identified. m Investigation by the licensee found no evidence of authorized work A routine surveillance test [d \ having been performed on the system. of the system, which had been successfully completed that day, did not require an alteration of the electrical power supply for the system.

V-86-13 12/18/86 Beaver Valley Duquesne Light Company Beaver County, PA ' At 11:10 p.m., during a shift changeover control room panel walkdown, an operator noticed that the " power available" indicator for one of six safety-related auxiliary feedwater valves was dark. An immediate investigation disclosed that the breaker for the valve motor operator was in the tripped position, but the valve was open, as required. The breaker was reset, and the valve motor operator was re energized at 11:20 p.m. No other indications of equipment tampering were detected. A review of the security access control records and the plant process computer records indicated that the breaker tripped at 9:45 p.m. and also identified five plant personnel who had been in the area at that time. Those personnel were interviewed. A l member of the contract security force (a guard) stated that he l may have bumped the breaker panel with his body just before i leaving the area. The licensee did not consider that explanation to be plausible, since physical protective devices had been , [a} \_./ installed on this and other safety-related breakers to preclude just such an occurrence. In a subsequent interview, the guard ___-_a

A-1 STATISTICS ) 12/31/86 (j l APPENDIX A - STATISTICS This appendix contains twelve graphs developed from data presented in the main body of this document. The figures reflect reported events from 1976 through December 1986, a period of eleven years. Data are divided into reactor and non-reactor events and among event categories which are generally consistent with those used in the body of the report. The significance of the variations in activity levels over the reporting period should be viewtd with caution, because reporting standards for safeguards events and criteria for including events in this publication have changed over the time period. Figure 1 provides an overview of the data base used for all figures presented in this appendix. Over 1,200 safeguards events were reported from 1976 through 1986. Safeguards events reported increased by more than 100 percent from 1978 to 1979, probably due to changes in reporting requirements and practices. After a period of stability, the total number of events reported in 1985 (120) increased by 38% in 1986 (166). This latest rise may be attributed to several factors: (1) the number of facilities has increased; (2) multiple events have occurred at certain facilities which have been Q the subject of public controversy; and (3) increased attention to reporting of events during the reporting period resulted from licensee participation during the public comment phase of a revised rule (10 CFR 73.71) on reporting events. This increased emphasis on the subject may have contributed in more meticulous reporting by licensees. Figure 2 shows safeguards events, excluding bomb threat events. The frequency of this class of evec,ts has been increasing over the past three years. Although some of the increase (26) from 1985-1986 may be attributed to the factors j stated above, 73% or 19 events fall in two categories, missing and stolen i events (10) and drug and alcohol related events (9). It is to be noted that 70% of the missing and stolen events involve licensed activities exempt from safeguards, whereas the increase in drug- and alcohol-related events may well ' be merely reflective of trends in the general population, as well as increased attention to detection of the problem by the licensees as a result of the Commission's policy statement on Fitness for Duty and associated industry-supported guidelines.

  /m                                                                                                                                                    ,

A-2 STATISTICS 12/31/86 O Figure 3 shows the distribution of the 1,230 events across the five NRC regions *. The higher frequency of events in Regions 1, 2, and 3 is directly related to the higher number of licensed facilities in these three regions, as compared to Regions 4 and 5. Figure 4 shows the number of safeguards events that have occurred at reactors. The rise of 39% (90 events in 1985 compared to 125 in 1986) may also be attributed to the same factors associated with statistics for all events (a 38% increase) as reflected in Figure 1. Figure 5 shows the frequency of reactor safeguards events, excluding bomb threats. In addition to being sensitive to the increase in the number of facilitins, there has been an increase of approximately 22% from 1985 (67) to 1986 (82), primarily due to the increase in reported drug and alcohol-related events. It should be noted that for the period 1983 through 1986, approximately one-half of the events reported in this group are drug- or alcohol-related. Figure 6 shows event activity for non-reactor facilities, which has increased by 11 (37%) over 1985 (30). Most of the increase is associated with events at materials licensees, who are exempt from safeguards requirements. These events were included because of public interest in this area. Figure 7 displays 1986 events by category. There has been no significant change in percentage of distribution of events from 1985. Figure 8 shows the number of bomb threat incidents over the 11 year period. Bomb threats, which had been declining steadily since peaking in 1979 (97), increased by 20 from 1985 (23) to 1986 (43). It should be noted that 9 of the 20 increase were directed at two facilities which had no bomb threats in 9 previous years, but which received considerable media attention in 1986. Figure 9 plots the number of intrusion events. With the exception of 1980, there have been relatively fsw intrusion events. There were no intrusion events in 1983 and 1986. Figure 10 shows the number of events involving tampering and vandalism. This class of events reported has been relatively stable. There has been a slight rise in events reported in 1986 (13), as compared with 1985 (11); however, the numbers are so small that the change is not significant. The slight increase probably reflects the increase in regulated facilities.

                 "These regions, which correspond to NRC organizational entities are made up as follows: 1 - CT, DE, DC, ME, MD, MD, MA, NH, NJ, PA, RI, NY, VT; 2 -

AL, FL, GA, KY, MS, NC, PR, SC, TN, VA, WV; 3 - IA, IL, IN, MI, MN, MO, OH, WI; 4 - AR, CO, ID, KS, LA, MT, NE, ND, NM, OK, SD, TX, UT, WY; 5 - AK, A2, CA, HI, NV, OR, WA. O

A-3 STATISTICS. l i 12/31/86 Figure 11 shows the number of firearms events that have occurred at all facili- ' ties. Many of these events involve the accidental discharge of weapons. None of these events has resulted in serious consequences. As a result of the increase noted in 1985, the NRC requested legislation making it a federal crime for a person without authorization to carry, transport, or otherwise introduce or came to he introduced any dangerous weapon, explosive, or other dangerous j instrument into any facility. installation or real property regulated by the' Commission. An additional 26% increase was reported from 1985 (19) to 1986 (24). Figure 12 shows the number of reported drug- and alcohol-related events. The  ! increased activity in this class (30 in 1985 compared to 39 in 1986) is believed to be directly related to the increased use of controlled substances in all segments of the population. As stated in Figure 2 above, the increase in events reported in this class probably reflects the increased attention paid to this area by licensees as a result of the Commission"s policy statement-on Fitness for Duty and the associated industry-supported guidelines. l O O l
