Searching

Three men (Eddy, Bob and Andy) eagerly looking for traces which point to a leak at the cover of the checkvalve.
We had a workpermit for the first checkvalve looking from the turbine downstream but the insulation guys unpacked the second one. So we were in doubt. Being no more pressure on it we had a problem. Mostly one can see traces where it has been leaking (because when medium- and highpressure steam escapes through a leak it has a kind of cutting effect).
We decided (also after making some phonecalls) that it really was the first one.
We have to wear helmets being in the plant but on this almost Blip we confiscated Bob's helmet because he has a light on it; easy to investigate the cover of the valve....
