Saidi said the seals will be removed because the installation of surveillance cameras has been completed.
Iran resumed some nuclear-related activities at the Isfahan facility yesterday.
The move prompted an urgent meeting today by the IAEA board of governors.
Following that meeting, IAEA Director-General Mohammad el-Baradei said Iran's decision hopefully represented only a temporary setback.
"I would hope that this is simply a hiccup in the process and not a permanent rupture," el-Baradei said. "We have made very good progress in the last couple of years with regard to clarifying Iran's past nuclear activities, and I will report to the [IAEA] board next month again on progress made on this issue."
Russia, which is helping Iran build a nuclear power plant at Bushehr, today responded to Iran's resumption of nuclear activities by calling on Tehran to cease all uranium conversion immediately.
