Exit Interview
The inspection scope and findings were summarized on March 24, 1988, with
the Operations Superintendent and members of his staff.
The licensee acknowledged the findings and took no exceptions.
The
licensee did not identify as proprietary any of the materials provided to
or reviewed by the inspectors during this inspection.

Licensed Operator Accelerated Requalification Training Program
On March 22-24, 1988, three inspectors from the Regional office inspected
the Accelerated Requalification Training Program as applied to licensed
operators in Group 4.
The program was conducted in the Training Facility
at the plant site. It consisted of both classroom and simulator training;
'the entire program (consisting of four groups) was implemented in early
1986 in response to the poor performance of the operators on.the Requali-
fication Examination administered by Regional examiners in November 1985.
The - inspection included confirming that training commitments were met,
reviewing written exams, reviewing simulator exam documentation, and NRC
regrading of selected written exams to ensure that licensed operators in
Group 4 had satisfactorily completed the training program and are ready
to perform licensed duties in the shutdown and refueling modes only,
until the NRC gives them requalification exams using the new methodology.
The new requalification exams will be given prior to Unit 2 startup.
The inspection team recommended to the Office of Special Projects manage-
ment that the 17 operators in Group 4 who had passed the TVA written and
simulator exams be allowed to perform licensed duties in the shutdown and
refueling modes.
The above also applies to an SR0 candidate in the hot
license class, who completed his training in March 1988.

The above _ inspection team recommendation was based on 'the following
inspection- team . observations, while using the guidance provided in
NUREG-1021, Operator Licensing Examiner Standards.
The inspectors reviewed the operator and senior. operator written exams and
. determined that the exams adequately covered the areas of principles of
nuclear plant operations for thermodynamics, heat transfer and fluid flow;
plant design; instrumentation and controls; plant operating procedures,
including normal, abnormal, emergency, and radiological control procedures;
and facility management controls.
The inspectors determined that the TVA grading of the written exams was
satisfactory by using the NUREG-1021 guidance of plus or minus 2 percent
allowance for regrading.
The selected sample of 50 percent regrading
included failing as well as passing grades (i.e. , 70 percent for each
,
category and 80 percent overall).
The inspectors reviewed the simulator exam documentation, along with
instructor documented comments to determine that the operators appeared to
perform satisfactorily during the simulator exam exercises.
The inspectors also reviewed the commitments addressed in the TVA Browns
Ferry Nuclear Performance Plan, Volume 3 related to operator training with
the following result:
a.
Completed commitment for increased training emphasis on thermo-
dynamics heat transfer, fluid flow, reactor physics, mitigating core
damage, and plant ar.d reactor transient analysis.
b.
Completed commitment for comprehensive weekly examinations followed
by a comprehensive final examination.
c.
Completed commitment to utilize emergency operating instructions in
simulator training.
d.
Completed commitment to not use uncontrolled reference material
during training on the simulator.
I
e.
(Open) Com.mitment to improve communication between operators durirg
simulator exercises was still identified and documented as an TVA
instructor concern during the Group 4 February 1988, simulator exams.
f.
Completed commitment for senior operators to effectively use emer-
gency operating instructions during simulator exercises.
l
g.
Completed commitment to have one week of classroom and one week of
l
simulator exercises on emergency operating instructions for licensed
operators as part of requalification upgrade training.

Completed commitment to ensure that only controlled copies of
procedures and drawings are used during simulator exercises.
i.
Completed commitment to rotate trainees in all operator positions
during simulator exercises.
j.
(0 pen) Operators deficient in communiciations skills will be given
additional training to improve skills.
This still appears to be a
concern as identified in e, above.
(0 pen) Af ter May 1988, the Browns Ferry simulator will have 42-46 modi-
fications made to make it similar to Unit 2 (instead of Unit 1) and at
that time the upgraded and revised Unit 2 procedures (emergency operating
instructions, general operating instructions, and plant operating instruc-
tions) will be used for simulator training instead of Unit 1 procedures.
The inspectors are concerned that all the operators may not receive
training on the ~ updated Unit 2 simulator and . revised Unit 2 procedures
prior to Unit 2 restart. This item will be tracked as Inspector Followup
Item (IFI 259,260,296/88-08-01).
The above i tems identified as open will be followed up i n future
inspections.
Based on the above NRC recommends that TVA utilize the 17 operators from
Group 4 (and one operator from the hot license class of March 1988) who
had completed the TVA Accelerated Requalification Program, and that they
be allowed to perform licensed duties in the shutdown and refueling modos
only, until the NRC can administer requalification exams which are to La
given before the Browns Ferry Unit 2 restart.
The operators are
identified by Docket numbers in the Attachment.
No violations or deviations were identified in the areas inspected.
The licensee stated that the Institute of Nuclear Power Operations and the
TVA Nuclear Managers Review Group are going to perform a training audit in
April 1988, and that the TVA Operational Readiness Review Team are to
perform a training audit in July 1988.
