A high level of trust is established in the organization, fostered, in part, through timely and accurate communication.

Industrial Safety Tip of the Week &nbspA (APM) Industrial Safety Coordinator:A A 533-6973 Heat Stress stay times per FCSG-15-8:

70 minutes in any area outside-followed by a 1hour break, or 45 minutes in any area outside-followed by a minimum 15 minute break.Radiological Safety Tip of the Week &nbspA (RP)Workers should doff PC*T"s slowly and one at a time to prevent cross contamination of exposed areas during the exit.In addition to possible cross contamination, the potential for loss of control of personnel dosimetry increases when multiple workers attempt egress at the same time.Human Performance Tip of the Week &nbspA (CAG)Turnovers:

The essence of a good turnover helps every individual understand where things stand at the beginning of the shift and what is expected to occur during the shift. Demand a proper turnover prior to taking on responsibilities or tasks already in progress.Training Excellence Theme for the Week &nbspA (TRNG)We Work Like We Train: We transfer behaviors and skills learned in training to the workplace a Standards in training are set at the highest levels Operating Staff &nbspA (OPS)6AM -6PM 6PM -6AM Shift Shift -Shift Manager Fred Klauzer Craig Longua CRS Julie Bissen John Musser STA Dave Spargo Scott Moeck WWM Adam Justice OCC Supervisor Jeff Yeager Adam Justice Jeff Yeager Shift Manager Report/Significant Events Last 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> &nbspA (OPS)Plant Performance Status as of: 07/17/2011 A 08:51 &nbspA (OPS)Power Level (Reactor)Power Level (Reactor)(XC105)

This effort has required each Remaining:

480 volt load center to be removed from service for investigation efforts and possible EOC.2) 1B3A & 1B3A-4A were inspectioned.

Bus 1B3A & 1B3A-4A was returned to service on 7/19. Bus A 1B3B will be inspected on 7/20. To date all buses inspected 1B4B, 1B3B-4B, 1B4C have tested satisfactorily with no problems noted.A 3) Buses 1B3C and 1B3C-4C will be inspected next week (7/25). These inspections will complete the EOC inspections associated with the breaker fire on 1B4A.4) The RCA Team has not finalized what created the electrical fault on 1B4A and subsequent fire.A The RCA is due to station CARB on 8/11/11. A new forensic engineer will be joining the team (7/19/11) to add valuable insight into the possible source of the electrical fault.Team Leader: Ken Erdman Recent CR # 2011-5750 Actions 1) Divers completed sand removal in the "C" cell 7/19. Accumulations ran from 0' 0" to a depth of 4'Remaining:

Average accumulation was less than 2'0". The plan is to dive the "B" cell 7/20.This work will be conducted monthly until the flood level recedes.A 2) The change to OI-CW-1 to include contingent suction for the Raw Water pumps will be issued as Rev 64, EC 53392. This change is in QR review by the "B" crew.A 3) Traveling screen vendor is on-site. Planning reports generation of a WO to remove the housing on "F" screen for observation/troubleshooting.

WOs have been generated for replacing the remaining power supplies.4) Replacement power supplies are being procured.

A schedule is being developed for replacing the remaining power supplies.5) The target date for completing the installation of the replacement RPS power supplies is 8/31/11; however, this date has yet to be validated.

4 Process and Area Radiation Monitoring System Reliability

'2010-3358 Sudhir Kalra Multiple failures of the Process and Area Radiation Monitors occurred in first (SE -Janet half of 2010. Six monitors (four process and two area) were declared Bozarth)inoperable from January 2010 through July 2010, limiting response organization ability to perform dose assessment.

All four process monitors and one area monitor were repaired and declared operable in last two quarters.

Engineering is addressing obsolescence issue of process monitors.Replacement of Rad Monitors is scheduled 2014 OL 3Q. One area monitor remains inoperable and is scheduled to be repaired during 2011RFO.5 Control Room HVAC System Reliability 2011-1133 Bernie Multiple failures of the Control Room Air Conditioning units have occurred Mierzejewski subsequent to July of 2010. During this time period, Control Room HVAC unit VA-46A has been declared inoperable five times and VA-46B once. The most recent failures were on 2/21/2011 and 7/22/2010 for VA-46A and VA-46B 10 respectively.

Both HVAC units are currently operable and performing their design function.6 RPS Reliability 2011-4451 Mark Bare During the 2010/2011 operating cycle, the following RPS failures have been reported per the 10CFR50.65 h*oeMaintenance RuleAE*-:

CR 2011-1304, Channel D VOPT peak detector alarm due to +5V Ref PS ripple; CR 2011-1278, AI-214 PS failure; CR 2010-6190, Channel A TMLP intermittent continuity fault affecting TU-6; CR 2010-5390, Temp sensitive math module -Channel B TMLP Calculator; CR 2010-2923, AI-3-M2 failure to open during test.
