(AP) — Regulators say the idle Fort Calhoun nuclear plant is making good progress toward restarting for the first time in more than two years, but some significant issues remain unresolved.

The Nuclear Regulatory Commission plans to provide an update on Fort Calhoun at a public meeting Tuesday night. The nuclear plant sits across from Iowa on the Missouri River about 20 miles north of Omaha.

Fort Calhoun initially shut down for routine maintenance, but significant flooding in 2011, a small fire and a series of safety violations forced it to remain closed.

The NRC says Fort Calhoun has resolved about 70 percent of the items that must be dealt with before the plant will be allowed to restart. And about 25 percent of the items are being reviewed.
