Plasma Inc./Broken Hill Nuclear Power Station

Broken Hill Nuclear Power Station (BHNPS) is a nuclear power plant facility roleplay experience developed and managed by the sci-fi development group Plasma Inc. 
Inspired by the RBMK-type nuclear reactors found at the Chernobyl Nuclear Power Plant in Pripyat, Ukraine, where the catastrophic Chernobyl nuclear disaster occurred in 1986, the game depicts a semi-realistic simulation of maintaining and operating a nuclear power plant. The facility is fictionally located in the outbacks of New South Wales, Australia, near the city of Broken Hill.
Originally conceived as the Pinewood Nuclear Power Plant (PNPP) by CzachuPL as an unofficial facility in early 2018, the game has undergone rebranding and transformation over time. In June 2018, it was rebranded as the Hyptek Nuclear Power Plant (HNPP) under the Hyptek group following their separation from Pinewood in October 2017. Afterwards, due to internal management issues within Hyptek, the game transitioned to Plasma Inc in August 2019 and was rebranded as the Broken Hill Nuclear Power Station, as it is known today.
The game has been featured multiple times on Roblox's Learn & Explore sort and currently amasses hundreds of players daily. At over 6 million visits, it is currently the fourth-most visited game in the sci-fi facility roleplay game niche, behind 's Quantum Science Energy Research Facility (QSERF).
==Areas==
===Main Power Plant===
The Main Power Plant is the central building in the BHNPS compound. The ground level consists of the Turbine Hall and two Reactor Halls, while the second level consists of two Reactor Control Rooms for each respective Reactor Hall. The coolant pumps, condensers, and other cooling equipment can be found on the sublevels below.
===Administration Building===
To the east, the Administration Building is a five-storey building housing recreational areas, utility rooms for the Plasma Security Division and Plasma Emergency Division, and various offices for plant management. A museum of old plant relics can also be found here. On the second floor, you can purchase single-use equipment and gears from Envvy, the equipment vendor.
===Emergency Bunker===
To the southwest, an emergency bunker can be found facing the Main Power Plant building. It is a scripted safe zone in the event of a reactor core blowout, provided that you are able to escape to it.
===Underground Facility===
The BHNPS has an underground research facility with research laboratories, warehouses, materials handling areas, and additional support offices. A backup generator can also be found on this level. Access to the underground level is provided by a road tunnel on the west side of the compound, a one-way exit elevator from the underground level, and through the ventilation system shared with the Main Power Plant.
===Rebel Encampment ===
Far outside the compound, a Rebel encampment can be found. It is only accessible to members of the Rebels team.
==Gameplay==
BHNPS has two nuclear reactors that operate independent of one another. There are also separate control rooms, turbines, condensers, and other apparatus for both reactors. The goal of the game is to keep the reactors functional to prevent any catastrophic events from happening. 
===Teams===
====Visitors====
The default role. All players are considered as visitors upon joining the game.
====Rebels====
The Rebels will attempt to raid the nuclear power plant and trigger a reactor core blowout or meltdown. The amount of players allowed on the Rebels team is determined by the amount of members on the Security team in the server. 
====Security ====
The Security team is responsible for maintaining safety and order in the nuclear power plant. They are authorized to deal with unruly or rogue personnel and biological hazards. To join the Security team, you must be a member of the (PSD) and must be wearing the official PSD uniform. Aside from purchasing uniforms from the PSD group store, you can also use the in-game !uniform command to automatically equip a PSD uniform free of charge.
===Reactor Core Blowout ===
If the pressure of any of the two reactors reaches a critical level of 10,000 PSI (689 BAR) an alarm will go off and soon after the generator will overload. Then a reactor core blowout sequence will begin. During a blowout, the reactor that reached the critical level first will be the first one to explode. This may also cause the other reactor to destabilize, causing the other reactor to explode as well. A blowout can be prevented by activating the SCRAM sequence using the SCRAM button in the reactor's control room, although it is not guaranteed. Once a reactor explodes, radiation from the explosion will affect all nearby players, causing them to slowly die. Afterwards, the game will restore itself to a pre-blowout state.
There are three possible endings with a Reactor Core Blowout:
*Either reactor goes into blowout. SCRAM is not triggered.
*Both reactors survive for 10 in-game days (4 real-time hours), then during a reactor core blowout, the SCRAM is activated.
* One reactor goes into blowout and the other does as well, but is saved.
===Reactor Core Meltdown===
If the temperature of any of the two reactors reaches a critical level of 1,400°C (2,552°F), a reactor core meltdown sequence will begin. During a meltdown, multiple explosions will occur within the facility, although not as deadly as a reactor blowout. These explosions primarily affect the underground part of the facility, along with the ramp entrance. Afterwards, the game will restore itself to a pre-meltdown state.
===Blackout===
On the other hand, if the pressure of both reactors goes too low, it will decrease the power output of the reactor and cause it to not produce enough electricity, causing a facility-wide blackout. During a blackout, some doors and machinery may not work. To avert a blackout, both reactors must reach normal pressure levels so that the power output will be back to normal. If re-stabling the reactor's pressure to a normal level is not an option, an emergency diesel generator can be found outside of the main building in a smaller building near the coolant towers, which can be used as an alternative power source, although it must be refilled regularly with the usage of trucks filled with diesel from a nearby refill. 
===Raids ===
Raids are triggerable events that can be initiated by the Rebels team by having at least three rebels and four security on the server at the same time. Raids can only be triggered every 30 minutes from the previous Raid.
A Raid lasts for 20 minutes. During a Raid, the Rebels are given access to a special version of the M4A1, Five-Seven and Riot Shotgun. These weapons are only able to deal damage to members of the Security team and do not deal damage to Visitors. Rebels are also equipped with crowbars for melee damage and a red version of the Riot Shield.
== Bugs ==
*The valves for Reactor #2 can be toggled if you are out of bounds on top of the underground.
* The crates can often clip underground due to the area loader unloading the surface and the player having network ownership of the crates.
* A corkboard within the administration building's cafeteria is floating.
* Toilet paper rolls in bathroom stalls have floating toilet paper rolls.
*A coffee machine within CzachuPL's office in the administration building is clipped into the wall.
*The security room's armoury door is not aligned with the top part of the wall.
*The group picture in CzachuPL's office in the administration building is floating.
*The phone and healing station in the large medical room in the administration building are floating.
*The bed in the small medical room in the administration building is clipping into the wall.
* An oxidizer pipe near the Tier 1 room is not properly connected.
*The found in the the office of TheCakeChicken and the underground vent system is missing his torso.
*The right stairwell is missing the plastic wall on the bottom floor.
==Glitches==
*Emote Clipping: Since the experience uses the R6 avatar rig by default, some rooms can be "clipped" into using the R6 dance and laugh emotes. These rooms include:
**Unused room formerly used for HED
**Security room
**The vent
**Tip gamepass room
**Inside of the starblox machines
**Inside of the left vehicle tunnel (The one behind the administration building)
**Under the map
**Inside of the reactor control panel
**Any other areas with a wall about a stud thick.
*Weighted Bunny Hop: Using the in-game !sit command with tools such as the Geiger Counter, M4A4, KRISS Vector, Five-Seven, Riot Shotgun, and some others will cause the player to fall face first. Furthermore, jumping will send the player jumping higher than usual or flung into the abyss depending on how it is done. This is due to mass being toggled on some of these tools.
* Gravity Coil Fling: If a player sits in a vehicle seat and jumps out with a gravity coil equipped, the player will be flung into space. This fling will not stop accelerating and the player will have to reset their character to get back down.
* Detain Tool Glitches: Using the detain tool, you can push players through walls. 
**If two users with the detain tool detain each other, they will be shot forward in a similar manner to two magnets repelling until one of them lets go.
**The detain tool can also be used to fling players if the player with the detain tool is seated using the in-game !sit command while facing the sky.
**The detain tool is also able to move seats if a detained player interacts with it.
*Taser Avoidance: A player will not be fully paralayzed if they are hit by only one prong of the taser.
**The paralyzing effect of the taser can also be bypassed using the in-game !sit command.
*If two players with gravity coils equip one in a fuel truck, the truck and the players will float in the air.
*The raider crowbar does not work after dying.
*The player can find a "pipe" tool which only acts as a invisible, non-functional prop.
*The player is able to drop speed and gravity coils that are part of their default loadout. This does not work with coils purchased from Envvy.
==Easter eggs==
*Saying "PRISM" and "Adonis" in the same sentence will show a special message in chat:
"[PRISM]: I am not based on Adonis, I only use Adonis' UI :(" 
*A green coil known as the "Forbidden Power" can be found outside of the plant, behind a couple of rocks.
* Former Hyptek owner Woofmacht can be found inside the vent at TheCakeChicken's office within the Administration Building and in the vent system underground.
*A crate with the Hyptek logo can be found outside of the plant, next to the left tunnel.
*A secret room can be found in the reactor room.
*There are multiple references to Black Mesa fan-made remake of the original Half-Life from the Half-Life series: 
**The health stations are recreations of the health chargers.
**The restrooms and changing rooms in the Underground Facility are based on the Sector C changing rooms.
**The PA system announcements are spliced versions of the ones used in Black Mesa.
*Some of the critical reactor announcements are taken directly from Portal 2.
* Multiple props and signage around the facility were adopted from those used in the Hyptek Tyonek Research Facility (HTRF) (now the Cobalt Valley Research Facility) when both games were still official Hyptek games.
