nuclear technology i do not think it is wise to use because the nuclear waste is too much nuisance. as you mentioned that there is no infrastructure and it needs more money to make a hydropower that was exactly what i was telling here earlier. but that is not just the case. when i say theoretically possible i meant it was impossible to achieve the potential limits. sorry to tell you this but without foreign help nepal can't even sustain itself how do you expect to build millions and billions dollars worth hydropower generating infrastructure. वातावरन पनि त सम्रक्ष्यन गर्नु पर्‍यो नि हैन ? hydropower भनेर जती मन लाग्यो त्एती गन्र्न काहा हुन्छ र ? oh please don't tell me that hydropower is environmentally friendly. you have been lied to. it is not safe as you think. i have done a project regarding this i know eventhough it looks clean and env-friendly IT IS NOT. if you don't believe it do some research. you will be surprised very few human made things are beneficial to anything othet than humans themselves.
