Teacher Tablet and ENECRA Missions

1. Hold and use the teacher tabletOn the power screen, press “Start training”. To run it in English, choose the language first with the globe button at the top left.
2. Choose to resume or start newAppears only when there is a record of the previous training. “Resume” keeps students' progress, what they placed, the teams and the collected handouts. “Start new” starts everyone from the beginning.
3. Choose the missions“Choose missions”, then “Solo missions” or “Team missions”, then the mission set. Students get their handouts and the missions begin.
4. Watch over them“Progress list” shows each student's progress.
5. Help students who are behindUse “Advance all”, “Give to one”, and back / on in the progress list.
6. End the training“End training” collects the ENECRA Tablets and handouts and puts the time and weather back. Everyone gets back the items that were kept safe.

What the top of the screen shows

Missions	The chosen mission set (solo or team).
Progress	For solo missions: for each mission, how many have cleared it and how many are on it.
Players	How many students are taking part, and the time since training started.
Time	Fixed at daytime during training, with clear weather.

Buttons

Before training, the power screen has “Start training” and a globe button (language) at the top left. In worlds that have Build Space plots, “Build Space” also appears after “Demo”.

• Until the teacher chooses the missions, a screen waiting for the missions to start is shown.
• The mission screen shows the mission set's name and how many are cleared at the top, with tabs 1 to 4. Press a tab to see that mission.
• Each mission shows its status (cleared or not), what to do next, a picture of the finished build, the goal, the steps (how far along you are), the handouts and key points.
• The top right of the game screen shows the current mission and step number (for example, Mission 3-4) and what to do next (the step list on the tablet uses the same numbers). In Missions 3 and 4, glowing dots mark the equipment used in the current step (only that student can see them).
• There is a globe button on the top bar, to the left of the ×. It changes the language of that student's screens only (when the teacher changes the language, everyone goes back to the teacher's choice).

Make power with renewables and light an LED through a wire. Next, make power with a BWR reactor and send it through the main transformer and switchyard to the model house's breaker panel. Each student works through the 4 missions in order, in their own spot.

1Renewable Power

Goal Set up four kinds of generators (solar, advanced solar, wind, hydro) and get them all making power

Steps

1. Solar generator making power
2. Advanced solar generator making power
3. Wind generator making power
4. Hydro generator making power

Handouts (given at the start of this mission)

Solar Generator x1Advanced Solar Generator x1Wind Generator x1Hydro Generator x1Water Bucket x1

Key points

• Solar and advanced solar generators make power where there are no blocks directly above (where they can see the sky)
• A wind generator makes power where there are no blocks above its blades
• A hydro generator makes power when water hits one side of its wheel (put water next to the wheel with a water bucket)

2Light an LED

Goal Run a wire from a working generator and light a blue LED

Steps

1. Place an LED
2. Connect it to a generator with wire to light it

Handouts (given at the start of this mission)

Blue LED x1Wire x64

Key points

• Lay wire in a line between the things you connect (wires next to each other join up)
• An LED won't light if the generator it's connected to is stopped

3Run a Nuclear Plant

Goal Build a BWR reactor and turbine building, then start the reactor and make power

Steps

1. Build the reactor
2. Load fuel
3. Secure feedwater
4. Connect station power
5. Send steam to the turbine
6. Cooling the condenser
7. Powering the condensate pump
8. Returning the feedwater
9. Start the reactor
10. Start making power

Handouts (given at the start of this mission)

BWR Reactor Builder x1Uranium Dioxide Fuel x10Wire x64Turbine Builder x1Steam Pipe x64Water Pipe x64

Key points

• A BWR reactor boils the water inside with the heat from fission, and the steam turns a turbine to make power
• Right-click the main control panel to see the operating status and the next step (hint)
• Port colors on machines: green port = wire, light-blue port = water pipe, red port = steam pipe (water pipes don't connect to a pump's green port, and wires don't connect to its light-blue ports)
• Station power (power to run the reactor) and power for the feedwater pump come by wire from a working generator
• You can load up to 5 fuel rods into a reactor nozzle (middle of the 2nd row from the bottom, on the 3 faces other than the front with the main control panel). The nozzles on the right and back have pipes attached, so load fuel into the nozzle on the left face. Fuel gets used up as it runs, so add more later
• Put fuel in the fuel tank behind the reactor and the fuel pipe refills it automatically
• Power the recirculation pumps on the left and right of the reactor for 100% output (without them, natural circulation gives 50%)
• Powering the circulating water pump cools the condenser with sea or river water
• The emergency diesel generator (to the left of the spot in front of the station power panel) links up when you place a wire in front of the station power panel; when the reactor stops, it starts by itself and powers the main control panel and pumps
• Station power (main control panel and pumps) totals about 2.2kW (recirculation pumps 0.5kW x2, circulating water pump 0.6kW, feedwater pump 0.3kW, condensate pump 0.2kW, main control panel 0.1kW). Wire it to the generators you placed in Mission 1 (solar 1kW, advanced solar 6kW, wind about 1kW, hydro 0.45kW). If one isn't enough, connect several
• The condensate pump draws water (condensate) out of the condenser and sends it to the feedwater pump (from the port at the left end of the condenser, through the condensate pump, then the feedwater pump, to the reactor). Wire the condensate pump too
• If you built in the wrong place, Builder Undo takes back your builders one at a time, newest first (the builders come back to your inventory too)

4Power to the House

Goal Build a main transformer and switchyard at the power plant's exit, and send the nuclear plant's power to the model house's breaker panel

Steps

1. Build the main transformer and switchyard
2. Build the model house
3. Connect to the breaker panel
4. Get power from the nuclear plant

Handouts (given at the start of this mission)

Transformer & Switchyard Builder (Compact) x1Model House Builder x1Wire x64Power Cord (White) x64

Key points

• The main transformer raises the voltage of the generator's power (about 20,000 volts) to send it far (a substation's job). The switchyard (gas circuit breaker and line take-off structure) connects and cuts the power line
• Hold the Transformer & Switchyard Builder (Compact) and right-click the generator terminal (green port at the bottom of the generator's end) to build in front of it (if the space in front isn't clear, right-click open ground to build). Then connect a wire from the generator terminal to the green port of the plant inlet
• The breaker panel is inside the house wall. Connect the wire from the plant outlet to the green port on the back of the breaker panel, on the outside wall of the house
• For the ceiling light, hold a power cord and right-click the ceiling outlet, then the ceiling light (it lights when the house has power)
• If you built in the wrong place, Builder Undo takes back your builders one at a time, newest first (the builders come back to your inventory too)

Build and run a PWR nuclear plant as a team and bring power to every team member's house.

Forming teams

• When the teacher chooses a team mission in “Choose missions”, a screen for choosing a team appears on the students' ENECRA Tablets.
• Students press a color button to make a team, or to join it if it already exists (up to 8 teams, any number of members, and they can leave if they join the wrong one).
• Once in a team, pressing a crew button gives that crew's builder and puts the student on that crew. Any number of students can share a crew, and one student can take two (one student can even do all four).
• During team missions, the turbine and switchyard builders leave the connections unbuilt (students place them by hand).

The four crews (in the order power flows)

How it goes

1. Reactor crew: build the reactor with the Reactor Builder and load fuel with "Refuel" on the main control panel
2. Turbine crew: build the turbine row near the reactor with the Turbine Generator Builder and connect it to the reactor with the main steam pipe (white) and the feedwater pipe (light blue). Put the water intake in sea or river water
3. Power line crew: build the switchyard with the Transformer/Switchyard Builder and connect it to the generator with the isolated phase bus (A red, B white, C blue)
4. Town crew: build houses with the Model House Builder and connect the power line from the tower to each house's breaker panel
5. Go through the startup steps on the main control panel to make power. Cleared when every team member's house gets power
