The nuclear reactor in Gecko is the source of much friction between that community and Vault City. The reactor is damaged, and is putting out a considerable spill of radioactive coolant into the groundwater in the region. People in Vault City are becoming ill due to this.
Both communities want the pollution stopped, but for different reasons. Lynette, First Citizen of Vault City, wants the pollution stopped because it's sickening her citizens. Harold, in Gecko, wants the pollution stopped because he knows, if it continues, it's only a matter of time before Vault City launches a military strike and kills off the ghoul population of Gecko.
You can blow up the reactor either by shutting off the coolant yourself, or conning one of the reactor's tenders to do it for you. The coolant report in Harold's desk is enough to get them to shut down the coolant system for you. The reactor melts down, and the problem is solved. The downside is now you are vilified in Gecko, and you've essentially destroyed the lives of dozens of peaceful ghouls, and now Lynette will not let you back into Vault City. She belives that the destruction of the plant will cause mass contamination and has the guards throw you out.
This approach takes a little more effort, but earns you both gratitude and more experience points than frying the reactor. After asking Harold what his job is, he tells you that the reactor has a broken part. The Hydroelectric Magnetosphere Regulator failed, and that's why the plant is pumping out radioactive coolant. The part needs to be replaced, but there's only one source: Vault City.
You may think that, with a solution in hand, Lynette would be happy to hand over the part and put the whole matter behind her. You would be wrong. Lynette will do absolutely nothing to help Gecko, even if it means helping her city in the process. Bringing up the idea can very easily get you banned from Vault City for good.
Instead, talk to Senior Councilmember McClure, in the large conference room nearby. He'll see the wisdom in repairing the plant, and send word to Randall, the Chief Amenities Officer in, as expected, the Amenities Office, to have the part ready. Fetch the part from Randall and return to Gecko.
Once inside the reactor control room, you have two options. You can make the run through the reactor pit room yourself, taking some damage and gaining some radiation, or you can reprogram the maintenance robot, an aging and cantankerous Mister Handy, to do the job. The problem with the robot is that its logic circuits have long since gone to that big computer in the sky. You need to map out its path, using machines as waypoints, before you can get it to install the replacement part. With the installation of a functioning Hydroelectric Magnetosphere Regulator, the plant runs clean again, and the radiation threat is over.
In order to fix or fry the plant with the use of the robot you must put in the following commands, in the reactor terminal, for the robot to work. (Incidentally, the order of commands is the same as the reverse order of the last 5 planets in the Solar System, before Pluto was declassified as a planet.)
1. Amplify Plutonium-Gamma Shield
2. Deharmonize Neptunium Impeller
3. Calibrate Uranium-Rod Driver
4. Set Voltage on Saturn-Class Capacitor
5. Test Jupiter Wave Complier
6. Install hydroelectric magnetosphere regulator to save the plant or turn cooling valve off
It may sound very complicated, but if you place the commands in the correct order and hit Execute Commands you can just sit back and watch the robot do all the work—or if you choose to demolish the plant, RUN!
Also, you can just give the hydroelectric magnetosphere regulator to Festus and he can install it for you. He wont want to install it first and you need to persuade him to do it. You earn 4250 XP for this.
Repairing the plant eases the tension between Gecko and Vault City, and unlocks another quest: to Optimize the powerplant.
Whichever way you dealt with the problem, Gecko's reactor is no longer a threat.
If you blew up the reactor, you get 2500 experience points (with a 550-point bonus if you braved the reactor pit and closed the coolant valve yourself, or if you convinced Hank to do it for you). However, talking to ghouls in Gecko will cause them to attack you, and the entire community will despise you.
However, if you repaired the reactor, you earn a handsome experience point reward. Doing the repair yourself earns you 4000 experience points, having Festus do the job earns you 4250 points, and using the robot to do the repair earns you 4500 experience points.
If you go to Den with a hydroelectric magnetosphere regulator in your inventory, the item will be stolen by Flick's kids. You will not notice that it is gone. However, you can take it back from Flick by bartering.
