incensed Staff Trainin
The inspector
examined the licensee's
program for training of
non-licensed staff to determine that it sati.sfies
regulatory requirements
and meets the licensee's
commitments for training.
The
.does
not.
specifically identify any nuclear or'industrial
standards
-to which the
licensee is committed.
In conversation
.with the training'manager, it was
determined that the licensee's
training program conforms to ANSI standard
"
N18. 1-1971 "Selection
and Training of Nuclear
Power Plant Personnel."
The
FSAR describes
training for non-licensed staff as follows:
Replacement training for operation
personnel
hired at Diablo Canyon prior
to April 27,
1984 followed established
company procedures
and programs
which required
new nonlicensed auxiliary operators
to undergo
a- formal 30
month training program.
This program consists of lesson
assignments,
review tests,
and qualification examinations.
Replacement training,for operation
personnel
hired. after April 27,
1984
is conducted in accordance
with .a plant manual
procedure.
Each
new
auxiliary operator
undergoes
a formal structured training program
consisting of two parts;
seventeen
weeks of classroom training,
and
approximately
24 months on-the-job watchstation qualifications'he
17
weeks of classroom training is in fundamentals
which includes
mathematics,
nuclear/m'echanical/electrical
sciences,
etc.
and systems
which includes. electrical/primary/secondary
systems,
and primary and
, secondary
support systems.
Matchstation gualifications,
an on-the-job
phase of traini.ng, prepares
the candidate to operate
components
outside
the control
room and to gain operating experience prior to taking over
the..sole responsibilities of standing .a watch.
This phase 'is divided by
watchstation ta give the. operator
a logical approach to qualification.
Replacement
training. for. nonopqrating personnel,
such
as technicians
and
craft journeymen, is conducted
as required by procedures.
Although these
positions are generally filled with experienced, personnel,
training is
provided to qualify individuals to perform the many specialized
duties of
these positions.
In general,. the training is accomplished
in two phases:
academic
and hands-on (on-the-job) training.
This training is, in
additi.on to the training provided under. the General
Employee Training
Program.
The inspector
examined
the, licensee's
prognam for training of nonlicensed
staff by reviewing. the followi.ng administrative procedures:
AP-B-150,- Rev. 1, dated June 25, 1986,
"Non-Licensed Operator Training
Program"
AP-B-450,
Rev. 1, dated August 21, 1985, "Instrumentation
and Control
Technician Training".
AP-B-750, Rev.,',
dated August 12, 1985,
"Maintenance
Personnel
Training"
The inspector
examined the following training records to determine if the
. above procedures
were properly implemented.
Auxiliary operators;
records for ten people of approximately sixty
nine operators-were
reviewed
0
IBC technicians;
records for seven people of approximately sixty
five technicians
were reviewed
.
Maintenance electricians;
records
for. eight people of approximately
sixty two electricians
were reviewed
It is concluded
from review of the administrative procedures
above
and
examination of the aforementioned training records that the training
program for non-licensed
operators,
I8C technicians
and maintenance
electricians
appears
to satisfy the training requirements
for these
disciplines
as described in the
FSAR.
The inspection in this area
was not completed during this inspection
period and-will be continued during a future inspection.
This item will be followed as open item 50-275/87-11-01.
No violations or deviations
were identified.

Thi.s TI outlines inspection requirements
for IE Bulletin 85-03, which
requested
licensees, to develop
and implement a program to ensure that
switch .settings
on certain .safety-related
motor-operated
valves are
selected,
set and maintained correctly to accommodate
the maximum
differential pressures
expected
on these
valves during both normal
and
abnormal
events within. the design basis.
The inspector
as
a followup to inspection report 50-275/86-31 selected
as
a sample
the following five motor operated
valves;
8107,
8801B,
8974B,
FCV-95 and
LCV-109 from the
27 valves of Unit 1 for which torque/limit
switch adjustments
had been
made during the Unit 1 refueling outage in
fall of 1986.

by
Foxboro, to deterioration resulting in equipment failure.
OIL 86-22-P, Failure of Milmar electronics
underpower relays to meet
gA
standards
required for nuclear
power plant
OIL 86-23-P, Stationary sleeve
on thrust bearing of Atwood 8 Morrill MSIV
must be machined to prevent galling.
The licensee
