The least rapid reaction probably has a nuclear drive. EMALS with nuclear steam generation already exists.
But what are we talking about, maybe Type 002 is built with gas turbines?
Too much risk to take I would say plus China doesn't yet has production model naval Gas Turbine in the range of 60-100 Mw
But they are working on it for sure Skywatcher has recent article on the subject
China's making major progress with its aircraft carrier tech
Say hello to China's first catapult-equipped carrier.

TYPE 002 CARRIER
This fan-made computer-generated image of the Type 002 by artist Nishikasaizoukan shows the craft's key features like catapults, J-15B fighters, and fixed-wing airborne early warning and control (AEW&C) aircraft.

Though China launched its much-ballyhooed Type 001A aircraft carrier just a few months ago, the People's Liberation Army Navy is hardly resting on its laurels, instead making steady progress on technology for its second home-built carrier, the Type 002.
The Type 002 carrier, development for which is slated to wrap in 2020 or 2021, will be a 70,000-ton aircraft carrier with catapults designed to launch heavier aircraft.
CGT-60F
The CGT-60F, seen here as a subscale model, is a class F turbine that can be used on warships like the Type 002 aircraft carrier.
And giant catapults aren't the only new tech in development. Pictured above, the CGT-60F is a heavy duty, F-class gas turbine (which typically have a power output of 170-230 megawatts) designed by Tsinghua University's Gas Turbine Research Center with the Dongfang Electric Group and Shanghai Electric Group. It's completely domestic design that exceeded expectations for cooling and temperature distribution—vital factors for large turbines. As such, the state-run
China Daily suggested that the CGT-60F would be a suitable candidate to power a large warship, such as an aircraft carrier.
