I haven't found any sources regarding this news yet, but I don't think this has anything to do with 093B (or 093G), which is not in active duty but a testbed for 095 SSN. For 093B, see these

New techs tested on 093B/093G do not include AIP, these are:
- Pump Jet Propulsion 泵喷推进系统 (despite Shenyang Machine Tool Plant has been successful in precision tooling of 7-blade propeller for the Song/Yuan-class SSK's, and 093-class SSN)
- New Materials (Hyper Strength Steel) 新材料(超高强度钢)
- Hybrid Single & Double-Hull Structure 单双混合壳体结构
- New Comprehensive Vibration Reduction Floating Raft 新型综合减震浮筏
- VLS for Cruise Missile 巡航导弹垂直发射管
- Third Gen Nuclear Reactor 第三代潜艇反应堆, HTGR, supported by new bearings, new thermoelectric converter
This AMPS is an alternative to other AIP like CCD, fuel cell or sterling engine, it is used for SSK only, so I believe 039B is very likely. There are cons of AMPS say higher costs, IR signature, radiation, etc., but pros are also very obvious, say it gives far more range and depth SSK to operate.

CCTV pic of interior of 039B, see their protection suit, here comes the speculation of AMPS-AIP. It should be one of many tech upgrades that 039B has implemented, compared to its predecessor 039A.
