ERDS SYSTEM AND PORTIONS OF PLANT COMPUTER OUT OF SERVICE FOR PLANNED MAINTENANCE OUTAGE
The licensee will perform a planned power outage on Unit 1 which will take the ERDS system, 25% of the control room annunciators, and portions of the plant computer out of service. Some points on the plant computer will not be able to be monitored during the outage. However, the licensee has compensatory measures in place to monitor those parameters on the control boards. The outage is scheduled from 0730 CDT until 1800 CDT.
The licensee will enter Technical Specification LCO 3.1.3.1 and 3.1.3.2.
The licensee notified the NRC Resident Inspector.
* * * UPDATE AT 1905 EDT ON 8/25/07 FROM ROGER SHALLEY TO S. SANDIN * * *
The licensee restored ERDS to service at 1805 CDT on 8/25/07 and will inform the NRC Resident Inspector.

AGREEMENT STATE REPORT - STUCK RADIOGRAPHY SOURCE
A representative from the State of Kansas contacted the NRC Operations Center to report a stuck radiography source. The source is stuck at Chanute Manufacturing Shop, 1700 South Washington Street, Chanute, Kansas. The company has a radiography shop and was performing a radiography shot of a drum when the guide tube stand fell approximately 2 feet and kinked the guide tube while retracting the source. The camera is an Amersham Model 880 with less than 100 Curies of Ir-192. The licensee reports the source is "stuck good". A 1 Mr/hr boundary has been established, and the area is secured. The state is unsure how far the source is from its fully retracted storage location. The licensee is attempting to locate a recovery team, and the State of Kansas is requesting assistance in locating a recovery team.
At 1110 EDT, the State of Kansas called back to report that the licensee has made arrangements with QSA Global of Boston, MA to come to the site today and recover the source.
* * * UPDATE ON 08/27/07 AT 1034 EDT FROM DAVID WHITFILL TO MACKINNON * * *
QSA arrived on 08/25/07 and completed recovery operations at 2017 CDT on 08/25/07. Highest dose received by a QSA person during recovery operations was 50 millirems as measured by an ion chamber detector.
R4DO (R. Nease) and FSME (C. Flannery) notified.

AUTOSTART OF ALL EMERGENCY DIESEL GENERATORS DUE TO A GRID DISTURBANCE
"A switchyard grid disturbance caused undervoltage relays to start both unit's Emergency Diesel Generators (EDGs). 1A, 1B, 2A, and 2B [EDGs] started which met ESF actuation [conditions]. The [EDGs] did not supply the emergency [buses] due to voltage returning to normal immediately. The grid fault was isolated and the [EDGs] were secured."
The EDGs are now available to respond if needed.
The licensee informed the NRC Resident Inspector.
