TLS 2

The TLS 2 was the 2nd iteration of the Tekkit Lite Server. It initially started as a survival server, however soon after it's launch it turned into a creative server.

This is the first main TLS iteration that Rez, Terry, Gery and Noel played on, with Koobs joining on 20th July 2019 and Domo1504K joining the server on the 1st August 2019, both playing on it for a while.

TLS 2 features:

• 4 AACR power plants, all differing from each other by their design or the number of reactors

• a rail network (TLS 2 Monorail System)
• a not even started oil processing plant
• glass-fibre power grid running throughout the desert
• various houses built by the members of the server
• a museum
• a coffee machine
• the ME Storage Facility (that no one ever used)
• as well as many decoration buildings.

History

The server was first started on the 18th of July 2019 by Rez after Terry invited him to the group chat on Discord, following a failed attempt at hosting the server on Aternos.

Survival Gameplay

Upon first joining the server everyone was in survival mode, and that's how the server was originally meant to be played.

However, the next day Gery said that he and Rez got bored of playing on survival and he asked in the Discord group chat whether the server could switch to creative mode.

Gery saying we got bored

During the time the server was in survival mode, a house was built, a primitive power source consisting of a BuildCraft engine powered by oil, as well as a very basic ME system.

Creative and First Power Plant

Immediately after switching to creative mode, the construction of the first Nuclear Power Plant on the server began. It was the first power plant to utilise the highly modified and upgraded version of TLS 1's Class II Reactors, later named AACR. It was also the first power plant that heavily relied on wireless redstone, starting a trend that continued over to every other power plant on the server.

Approximately 2 hours after switching to creative, a test of the reactor design failed miserably.

Second Power Plant and the City

After the completion of Unit 1 on the 20th of July, plans were immediately made to construct a second, bigger powerplant nearby. the "Big NPP" would feature the same AACR design, but with several reactors strung together to a single power output, generating more than enough power to satisfy the growing energy demands of the nearby settlement, later named ATOM Town.

Alongside the construction of the plant, many other buildings would begin popping up around the area, serving both functional and aesthetic purposes. Private houses were built by server members, machines, factories and training grounds began popping up. This is also when the Koobs Coffee coffee machine was constructed by Kuba0040. Although being a creative server, transportation was also improved with the creation of roads, pathways, and the TLS 2 Monorail System.

This period also saw the debut of the Fiberglass Grid system, a necessary innovation designed to efficiently carry and distrubute the electricity produced by the two units.

Third Power Plant

For their next project, the server members decided to construct a power plant designed exclusively for roleplay and training purposes. As a result of this, Unit 3 featured no passive safety features or automatized feeding system, and several design elements allowing operators a more direct form of reactor control. Construction began on the 22nd of July, 2019.

Shortly after completion, the Nuke incident would occur, destroying a significant part of the plant, aswell as a nearby oil refinery. Initial plans included covering up the wreck in a sarcophagus, or turning it into a museum. Eventually the plant would be rebuilt to operational capacity, though the scars of the explosion could still be seen. Some world downloads feature a basalt layer covering up damaged portions of the plant.

During this time both the rail and power grid systems were expanded, and more buildings were constructed.

Power Plants

All power plants on the server, despite AACR's capability to auto-refuel, never implemented the automatic creation of Quad Uranium Cells, due to that, most of the power plants within world downloads have their reactors with only depleted uranium cells.

Unit 1

This was the first ever power plant built on the server by the members. It was the first one ever to use the AACR design.

All of the Control Rooms wiring was made by Rez and is left outside the powerplant for everyone to see (and destroying the look of the environment). It also is the first time wireless redstone was used for controlling reactors on the server, which started the trend for every other power plant.

The reactor exploded once, while the power plant was being constructed.

The power plant ultimately had a single AACR reactor, fully featured with EDS-2 and EDS-5 and output power monitoring.

The name of the reactor in NPP 1 is Big Boi V2.

Unit 2 "Big NPP"

The NPP 2 was the biggest power plant on TLS 2, featuring a total of 12 AACR reactors, totalling an output power of 33,600 EU/t.

It is important to mention that while we consider the entire plant one unit, functionally all 12 reactors had separate controls, cooling, and forcefield capabilities, with power output and some secondary safety measuers being the only major common elements between them.

Unit 3

The 3rd NPP on the server was meant to be a "roleplay npp"

Nuke at Unit 3

On 22nd July Noel pressed a button, behind which a nuke was placed, in order to access the rooftop of the power plant.

The power plant promptly exploded destroying around 6-8 hours of work done on the power plant.

Noel was framed for the explosion and the original saboteur remained a mystery for a while.

Eventually Rez revealed he was the person who placed the nuke behind the button, while he made a backup of the server's world before the nuke was exploded, the save got overwritten by newer world region files and in the end, there was only a save with an exploded NPP 3.

Unit 4

NPP 4 was the first power plant built by Domo right after he joined the server in August.

It was designed to be the safest power plant on the server, featuring safety features such as:

• the entire building being constructed from Reinforced Stone
• emergency procedures
• each reactor being in it's own room
• flooding reactor rooms with water in case of overheating
• replacing Quad Uranium Cells with Overclocked Heat Vents to instantly decrease the temperature inside the reactor.

It's also the only power plant on the server to exclusively use the Polish language.

The reactors used a slightly modified version of the AACR design to facilitate the safety features.

Most of the power plant's cabling is hidden under the control room (finally) making it hard to see from the outside.

The power plant was also meant to include a power distribution plant inside it, however while the room for it was built, the technology never got designed.

Flaws

There were a few flaws related to the safety systems inside the reactors. While being flaws, they didn't impact the safety of reactors.

• Due to problems with the ME system not handling NBT data correctly, using emergency procedures to replace Quad Uranium Cells with Overclocked Heat Vents, often resulted in flooding of the ME system's storage with partially used reactor components, as well as not always exporting all Uranium Cells or Heat Vents out of the reactor.
  • The partially used reactor components would also be unable to go inside the reactor again upon disabling the emergency procedure due to the same NBT issues with ME system.
• Flooding the reactor rooms with water often resulted in them being flooded indefinitely due to problems with water source blocks and Grates used to pump water in and out of the rooms. Due to that the rooms are usually left partially filled with water.

Unit 5

The NPP 5 was meant to be a new power plant on the server, the design of which was mainly inspired by Unit 3 and 4 of ChNPP.

Despite the plans of building it, only a rough blueprint of the power plant was build on the ground west to NPP 4.
