Re: ALARA Dose Tracking

>to what extent other nuclear utilities, especially Power Stations 
perform dose tracking.  Do you calculate the dose per task, i.e. a 
task being for instance the removal of a pump impeller.  Or do you do 
dose tracking by activity, i.e. the 'C' Service of a pump<

The answer to this question depends on many factors. One must consider the 
collective man-rem estimate for the job and if it is worth having many Radiation
Work Permits (or whatever paperwork or computer generated forms are utilized) to
cover various evolutions of the job. If the task is repetitive, and one is 
proactive in attempting to reduce the exposure for a total job, it is necessary 
to stratify the job into its many components to determine where the majority of 
the dose is received in order to identify where ALARA attention is necessary to 
cause actions to be taken that will facilitate an overall dose reduction.

Generally, we track by RWP (main evolutions) by Department as well as to the 
individual level who works on the RWP. The dose information is tracked as to 
actual dose received compared to the estimated dose expected at any point in 
time. It doesn't help to know that the dose or man-hours has been exceeded AFTER
the job is done. It is important to know as early as possible that the job has 
gone off target, so that the necessary countermeasures can be implemented.

If an RWP exceeds the target, those accountable for supervising the job are 
required to report in detail what went wrong, why the dose was exceeded and what
steps need to be implemented in the future to ensure that the job proceeds as 
expected. Pre-job and post-job ALARA briefings are essential, on high dose jobs,
to reduce the job the next time it is worked. The workers who work the job are 
the most obvious source of finding ways to do the job more efficiently in less 
time and less dose, but also doing the work in a safe manner as well.
