The B&W requalification training program is primarily intended to improve the plant operator's ability to control the plant under abnormal conditiens. The 7
abnormal conditions which are considered are derived from License Event Reports z--
--4 (LER's) and discussions with personnel at the plants.. A visit to each site is eMW5 i5niihWN made just before requalification training starts to meet with on-shift personnel, operations supervisors and training in order to tailor instruction to specific W
gg6 plant problem. Events are shared a:nong plants so that the Oconee operators are exposed to SMUD problems and vice versa among all our plants.
ls _-
fach requalification group is exposed to at least the following actually occur-ring problems during their operating period on the simulator:
-s 1.
Failed close main feedwater valve
=
Et 2.
Reactor trip without turbine trip 3.. Propped regulating or safety rod' 4
Tav failure both Th and Tc caused (ICS input) 5.
Spray valve failure 6.
Headge pressure failure (ICS input) ej 7
Less of ICS power - controls fail to mid scale
- M-E a c.,,
8.
Lead rejection

.r,7 9.
Turbine trip q y' g3ia(2
- 10. Steam generator tube leak i

- 11. Feed flow instrumentation failure 1
l During operations, students operate with the various ICS stations in automatic and manual to demonstrate parameter effects on plant operation. These drills demonstrata:
1.
Importance of each parameter on system operation.'
2.
What parameters are important to monitor.
3.
Proper response to instrument failures are usually maintenance t

Occurr;ns : alfunctiens are postulated and their effects are determined by the students. Drebim occurring at etner plants-are posed anc discussed i'i the context of what should be cone at their plant.
Typical of these problec.5 are the loss of tal power at Rancho Seco and the loss of ICS power at Crystal River.
