Incident Report
Facility: East Valley Nuclear Plant Date: 12/10/2021 Report ID: 9603120071 Event description: Roughly 18 hours prior to the incident, an Amazon package containing fireworks was mistakenly delivered to the reactor control room and left under the console. The next day, at approximately 14:00 , Technician A arrived at the facility with a bag containing four juggling pins. At 14:20 , Technician A entered the control room, and joined Technician B at the console. At 14:28 , Technician C exited the elevator and approached the control room holding a birthday cake intended for Technician B. At 14:29:22 , Technician A said "Hey [Technician B], check out this cool trick I learned" while taking out the juggling pins. Technician B turned to look just as, at 14:29:26 , Technician C entered holding the cake.

An incident report describes the sequence of events when something goes wrong, including the lead-up as well as the aftermath. This usually involves describing at what time related events happen. In this comic, a report at a nuclear power plant on the day of the comic's publishing starts with particularly vague timestamps (that a package of fireworks arrived "roughly 18 hours prior" to it), then uses approximate minute-level precision ("14:00" and "14:20", which could reasonably be five minutes off in either direction), then minute-level precision ("14:28"), then second-level precision ("14:29:22" and "14:29:26").
This suggests that the clock time is really a proxy for the amount of time before one specific moment where everything falls apart, and when seconds start appearing, it implies that the recollection is within a few minutes of the disaster. Normally the increased level of precision reflects close monitoring capabilities of the affected systems, reviewing monitoring equipment, such as surveillance camera and microphone recordings, and/or detailed analysis by incident investigators. It may have been sufficient for the resulting inquiry to merely note the prior arrival of the original package, and possibly then read off (whatever remains of) the signing-in logs for the approximate times each member of staff arrives on the scene. At some point, though, the investigation will refer to fully timestamped security recordings, perhaps even eventually frame-by-frame with particular interest in exactly which things touched exactly what other things, in sequence, in order to hopefully learn all the necessary lessons about the incident.
Synchronization of events is important in incident investigations , so often systems are required to take input from common, relatively precise time references, such as GPS , WWV broadcast , or cellular telephone systems. For example, an aircraft crash needs radar positioning data synced with voice communications and flight recorder data .  Lack of correlation between these is a potential source of conspiracy theories, for example one of the hijacked planes on 9/11 crashed into Pennsylvania either at 10:03 or 10:06 depending on two different information sources.
In many situations, incident reports are anonymized as shown to protect the identities of those people involved in the incidents. This is often done to prevent unnecessary blaming of certain individuals, particularly when it hasn't yet been determined whether the incident was negligence or just an accident.
Examples of real-life incident reports with second-level precision timestamps showing the increasing precision around critical moments include:
The report shown cuts off before reaching the actual incident, leaving it to the reader to imagine what happened next. If the birthday cake has lit candles, one possible sequence of events is that a dropped or badly thrown juggling pin could have hit one of them and then rolled over to the fireworks package, thus igniting the package. This would have caused the fireworks to go off underneath the reactor control's console.
Although the comic refers to juggling "pins" , jugglers commonly call those props "clubs." It is possible Randall is confusing the similarly shaped objects in 10-pin bowling to juggling clubs. "Pins" are another name for a component of Uranium Carbide type nuclear fuel rods , which are involved in the safe control of the nuclear reaction within a nuclear power plant. No sane reactor staff would juggle these complex, heavy and expensive pieces of equipment. [ citation needed ]
The title text refers to the theme music from the 1975 film Jaws , which has come to represent impending danger. Movies use music to create the correct emotional tone; suspenseful music indicates that something bad is about to happen. The Jaws theme is an iconic example, famously used to create a sense of foreboding, then uses increasingly rapid tempo to build a sense of imminent danger, culminating in a dramatic moment of disaster (a shark attack, in the film). As with the increasing tempo of this theme, the increasing precision with which events are recorded in an incident report build the increasing sense that something terrible is imminent.
9603120071 is an actual accession number for an incident at San Onofre Nuclear Generating Station in 1996. Four slightly contaminated stray kittens were found, cleaned, and adopted. No clock times were mentioned in the report.
Real-world nuclear power stations have strictly regulated control rooms which would prevent the simultaneous presence of fireworks, juggling and birthday celebrations. [1] [2] There is no East Valley nuclear power plant, but there are two reactor units at the nuclear power plant in Beaver Valley, Pennsylvania.
