This week's theme isClose Calls or more specifically, what we call near misses. Learning from close calls should be looked on as golden opportunities to prevent actual accidents. Let's not miss out on this opportunity.

';' the danger-save a stranger" OEfrom UlR27-A compressed gas cylinder incontainment stored Inawalkway, was not secured. The cylinder was bumped by a worker and fell over. Fortunately a co-worker noticed the situation and caught the cylinder before any damage could be done. Are all of our compressed gas cylinders secured?

'When you fall to report a hazardous condition, you may contribute to employee attrition' Near-miss failure story:

A co-worker is using a ladder. It seems fine, but as he comes down, one of the rungs sags as he steps on it. He notices a crack. He puts the ladder back without tagging it as needing repairs. The next day you grab the same ladder. As you start to climb you put your foot through the rung, lose your balance and fall, spraining your ankle.

Do you check Vour ladder before you climb?

'Qeport and repair or someone mnay despair" OE1 7263 Comanche Peak - A worker leaned back Inhis chair when the screws holding the back of the chair to the body separated and he fell back to the floor. Examination of the chair found that only a single screw was holding it together. By someone not reporting this situation, a lost time accident occurred.

"Sidestepping a hazardous condition leaves others at risk of hospital admission' A worker was attempting to remove a water tank from a piece of heavy equipment. He was removing some bolts not realizing that they were the only support for the heavy tank Itself. When the last bolt came out, the 1,200-pound tank fell on the victim, crushing his chest. He never regained consciousness, and died of the Injuries.

Investigation showed two years before, a similar Incident had occurred Involving another worker. The worker Involved had escaped with only a bad scare but the condition was not corrected.

Luckily the person was not injured. The pedestrian was walking in an open area and thought the driver had given him the right of way. However the driver of the truck did not see him. Has a near miss like this happened at PBNP?

"Most obituaries would not be recorded if all close cal/s were reported" It hanoened at Prairie Island:'

A year ago, somebody damaged one of the roll-up doors with a hydraulic lift. Unfortunately the employee failed to report this mishap and later the door fell narrowly missing another employee. This time we were lucky however the whole thing could have been avoided ifonly the damaged door were Identified and repaired.

• UIR28 Point Beach Nuclear Plant U1R28 Operating Experience Monday, April 5, 2004 (for work Wednesday, April 7, 2004)

OE subject:

OE10285 - Unit I Core Exit Thermocouple Indication Lost While RCS was in a Reduced Inventory Condition

Purpose:

This event provides an example where the primary means to monitor shutdown cooling was lost Why we chose this OE for today:

Conoseals are scheduled to be removed on Wednesday April 7h. 2004.

Discussion:

On April 21, 1999, with Prairie Island Unit I in cold shutdown, electrical maintenance personnel were disassembling instrument port conoseals on the reactor vessel head when a control board annunciator alerted control room operators that thermocouple indications were lost. An electrician disconnected a group of four thermocouples and was to reconnect them before disconnecting a second group of four thermocouples. The electrician inadvertently reconnected the wrong multipin connector'for the first group and continued disconnecting the cables from the second group, which initiated the control room annunciator. Core exit thermocouple indications were unavailable for approximately one hour before the cables were properly connected. During this time reactor coolant system temperature was monitored using residual heat removal system inlet temperature, which remained at approximately 115 degrees Fahrenheit. The cause of the event was an inadequate procedure. The procedure did not require verifying the first thermocouple group indications after the cables were reconnected before continuing with disconnecting the second thermocouple group. Contributing to the event was less than adequate prejob briefing. The electrician did not understand or was not provided with information that would have prevented him from connecting to the wrong pin connectors. Corrective actions included revising three electrical maintenance procedures to ensure verifying the minimum number of thermocouple indications remain operable while in reduced reactor coolant inventory. This event is not significant because reactor coolant system temperature remained constant and was monitored by alternate indication.

Questions:

What human performance tool could have helped prevent this as it was happening?
