given by Facility Operators from the MMI. Alarms are displayed at the
MMI for variables out of limit.
The operations ongoing at TSTA fall into two distinct operating
modes, loop and nonloop operations. TSTA process flow loop operations,
generally involve approximately 100 grams of tritium circulating in the
loop. During loop operations at least two knowledgeable TSTA personnel
must be on site monitoring the process at all times. We currently are
operating with three eight hour shifts. The two shifts during the day
are operating shifts, while the night shift is a holding shift. There is
at least one Facility Operator as a member of each shift. The length of
the loop operations is usually one to two weeks. One of the limitations
on the length is the small TSTA staff. The frequency of loop runs is
currently five to six per year. In the next several years the length of
these runs will increase to a duration of several months.
During loop operations, the small scale nonloop experiment; are
also done. However, the activity of these experiments may decrease since
loop operations generally require participation of most of the TSTA
During loop runs, TSTA personnel are given variou-
responsibilities. A Test Director for each shift '- designated. The Test
Director is in charge of the operation of the experiments. He or the al-
ternate must be onsite at all times. On each shift one of the Facility
Operators is designated the Loop Operator The Loop Operator handles the
control of the loop operation from the MMI. The various other TSTA per-
sonnel have responsibilities for the local operations necessary lit the
various sVstems such as gas analvsIs and attaching and detaching tritium
containers. The loop operator and test director coorinate all the
operations from the control room. Whenever nteVess. . V. consul t inp,
personnel are incl uded in the disc ussions. For off hiermal nr eIergenev
situations, TSTA personnel whom are considered experts are assigned to
Pacth system. These are the personnel who the T'est 1:r4cor consults
