-Goal of Training:

The purpose of this training is to provide both contract and permanent individuals the opportunity to practice working with nozzle dams using available RP materials, equipment and supplies in an environment that simulates actual conditions in the field.

In addition, it is extremely important for each group to understand each others roles, responsibilities and expectations during this evolution. This training will help establish this understanding.

Learning Objectives:

Upon completion of the Just-In-Time Training, Radiation Protection personnel will demonstrate the ability to:

• Properly dress personnel for entry into the simulated Steam Generator using HPIP 4.58, Issuance of Respiratory Equipment and the guidance in the appropriate RWP. (HPC.04.LP203.001)

• Maintain proper airline respirator controls using HPIP 4.58, Issuance of Respiratory Equipment. (Permanent WE Energies personnel only)

(HPC.04.LP203.002)

Properly undress personnel exiting from the simulated Steam Generator.

(HPC.04.LP203.003)

• Provide proper radiological controls for personnel entering and exiting the simulated Steam Generator using the guidance in the appropriate RWP.

(HPC.04.LP203.004)

Upon completion of the Just-In-Time Training, contractor personnel (for nozzle dams) will demonstrate the ability to:

• Properly wear and utilize protective clothing, including respiratory protection equipment, while entering, working in and exiting the simulated Steam Generator using the guidance in the appropriate RWP.

(HPC.04.LP203.005)

• Properly install/remove a nozzle dam while complying with the appropriate RWP and Work Order. (As applicable) (HPC.04.LP203.006)

Prerequisites:

What's In It For Me? (VVII-FM)

a.

The use of nozzle dams is intended to save critical path time during outages. It should be recognized that personnel could install a dam in about 2 minutes and remove the same dam in about 1 minute.

b.

There are multiple industrial and radiological hazards associated with the use of dams. This training is an integral contributor to the ACEMAN concept:

1) Accident Free - practicing the task, utilizing OE and identifying potential accidents minimize the possibility of causing an injury.

2) Control Dose - practicing this task will significantly reduce exposure because of improvements in both effectiveness and efficiency.

3)

Event Free -following all procedures, work orders and administrative requirements will reduce the potential of having an event occur.

4)

Meet Schedule - in order to meet the schedule all players must understand their specific roles and responsibilities.

5) Attend Training - we are meeting this concept by conducting the JITT.

6)

No Rework - we need to be able to identify any potential pitfalls, JITT will help do this which will reduce the possibility of any rework.

Job Planning/preparation and verifying we have qualified workers are two barriers we will have in place to ensure we will have a successful evolution.

c.

This training is intended to familiarize personnel with using these dams and to ensure everyone associated with the evolution is aware of the requirements and can safely perform their function. Remember, teamwork, partnership, safety and learning are all key attributes that this JITT session will be promoting.

c.

Unclear results regarding actual scfm at hood

d.

2.

Stopping work when unsure

a. Less than adequate, if unusual conditions or events occur that were not anticipated, the job should be stopped

b.

If the job is stopped, all workers will exit containment to evaluate the situation.

Workers will be re-briefed on changes and job will recommence.

HPC-04-LP203, NOZZLE DAM JUST-IN-TIME TRAINING, Rev. 0 Review OE 48685, Two separate Incidents Where Loss of Breathing Air to Air-Supplied Respirator.

The use of the CJEN connections has effectively reduced the possibility of airlines being disconnected.

The platforms have been arranged such that the stairs allowing access to the manway openings can be used for both SIGs. It is not acceptable to use another means that could result in pinching or cutting an airline.

Work Order properly controlled and maintained D. Nozzle Dam Installation This section only applies for Nozzle dam installation and is not required to be completed if evolution is nozzle dam removal.

EX-2 Exercise 2 includes:

1. As dressed during exercise 1, participants are to jump the Steam Generator and install the nozzle dam with help from the designated helper.

2. RP will maintain breathing air/communications during bubble hood use.

3. RP will properly cut individuals out of their plastics and bubble hoods upon exit from channel head.

Participants are to use the appropriate RWP1WO with input from RP to complete each of the above items. Individuals are allowed to complete the item more than once to gain familiarity, confidence and efficiency.

LO 002, LO 003, LO 004, LO 005 and LO 006 Review OE 18109, Radiological Conditions Encountered During Steam Generator Primary Side Maintenance Activities.

After ECT, it is not uncommon to change the conditions both inside the SIG and on the platform. At PBNP, an activity exists requiring the platforms to be decontaminated between ECT and other work with the SIG. Radiological conditions inside the channel head will need to be determined to verify adequacy of the RWP.
