Could be true for the ones with ICBM range. As for mid-range rockets, he may have enough already. Kim may say he won't do another ICBM test but can launch a rocket to put a satellite on orbit. They would claim that it is not an ICBM, but a ‘peaceful space exploration.’

Since KN can not use Mount Mantap for additional nuke tests, the mountain will collapse (1), they have to build new tunnels somewhere and that will take more(?) than a year. This implies that Kim can say that he will stop the nuclear tests (for now).

(1) But another reason could be a tunnel collapse there. About a dozen earthquakes of magnitude 2.0 and greater have been detected at the site since the nuclear test last September.
Mt. Mantap, where the nuclear tests were conducted, reportedly sank about 3 m in the wake of the earthquakes.
A researcher with a government-funded think tank here speculated, “It's possible that the regime has decided not to use the site for a certain time due to the danger of collapse.”
