Total U.S. nuclear plant availability rose early May 30 to 89.12%, up from 87.03% on May 26 but still remained below the 94.17% reported on the same day a year ago.

Pulling up total production was the return of two reactors. Public Service Enterprise Group Inc.'s Salem 2 plant in New Jersey was warming up at 1% early May 30. The unit was taken offline mid-April for planned seasonal work. Exelon Corp.'s Clinton Power Station in Illinois was at 16% early May 30. The unit was shut May 9 for a refueling outage.

In addition, two other units returned to full power. Exelon's Limerick 2 in Pennsylvania was at 100% power early May 30, up from 3% on May 26. The Peach Bottom 3 plant in Pennsylvania, which is owned by Exelon and PSEG, was operating at full power early May 30, rising from 45% on May 26.
