This is a trick question. 🙂

The difference between wait and await is that wait is intransitive and would take a preposition if there is an object following. Await is transitive and takes a direct object.

We are waiting for your plan.
We await your plan.

However, the example that you gave is in the passive voice. Clearly, you have to use await in the passive voice because you cannot use intransitive verbs like wait passively.

If there is a problem with the sentence, it is that the sentence probably does not make sense. If you put this sentence in the active voice, you would say, “The startup of the reactors awaits your plan.” This in most contexts would not make sense because people wait, not startups.

Do you mean to say, “Your plan awaits the startup of the reactor”? If that is the case, the passive voice would be “The startup of the reactor is awaited by your plan.” This is awkward, but it is grammatical.

You probably can come up with a better way to express what you are trying to say. Consider also the progressive tense.

We also note that in some English dialects people say “wait on” instead of “wait for.” In most dialects, though, “wait on” refers specifically to helping or serving someone–why attendants in restaurants are called waiters.
