FRIB dri­ver linac will de­liver all sta­ble heavy ion beams with beam en­ergy more than 200 MeV/u, and beam power on tar­get up to 400 kW. As the first SRF linac for high power heavy ion beams, there are many tech­ni­cal chal­lenges, and in­te­gra­tion of all the ac­cel­er­a­tor com­po­nents is im­por­tant. In this paper, major is­sues on in­te­gra­tion of the FRIB drive linac are in­tro­duced and the cor­re­spond­ing stud­ies are dis­cussed, which in­clude de­vel­op­ments of ac­cel­er­a­tor on­line model, min­i­mize un­con­trolled beam loss in the SRF linac for high power heavy ion beams, beam di­ag­nos­tic sys­tems for beam tun­ing and for ma­chine pro­tec­tion sys­tem (MPS), sec­ondary col­li­ma­tors for charge se­lec­tion of multi charge state ion beams, beam load­ing and sta­bil­ity of LLRF con­trol, proper de­gauss process with su­per­con­duct­ing (SC) so­le­noids when com­bined with SC di­pole cor­rec­tors, vac­uum sys­tem, cryo­genic and dis­tri­b­u­tion sys­tem, he­lium pres­sure drop and sta­bil­ity of the cry­omod­ules.

FRIB linac dri­ver in­cludes a front end and a SRF linac for all sta­ble ion beams with en­ergy more than 200 MeV/u, and beam power on tar­get up to 400 kW. A 80.5 MHz FRQ at the front end ac­cel­er­ates heavy ion beams from 12 keV/u to 0.5 MeV/u, in CW mode. De­sign of the RFQ is in­tro­duced and sev­eral im­por­tant tech­ni­cal is­sues are dis­cussed in this paper.
