| Thermal power per reactor (MWt) | 58 | 165 | 17 of 19 |
| Entered service | 1987 | 1997 | 7 of 17 (earliest first) |
Worked out from the entries on this site only, so a figure compares Xia class (Type 092) with what is recorded here, not with everything that exists. An entry with no value for a measure is left out of that measure's ranking and median.
