I. INTRODUCTION-
<
'The Systematic Assessment of Licensee Performance (SALP) program is an
integrated NRC staff effort'to collect available observations and data'on 0'
a periodic basis and to evaluate licensee performance based upon this
information. The program is supplemental to normal regulatory processes 3
used to ensure compliance with NRC rules and regulations. It is intended ;
to be sufficiently diagnostic to provide a rational basis for allocating. :
'
NRC resources and to provide meaningful feedback to licensee's management
regarding-the NRC's assessment of their facility's. performance in each.
functional area. ;
An NRC'SALP Board, composed of the staff members listed below, met on
June 13, 1990, to review the observations and data on performance-and to
.
assess licensee. performance in accordance with NRC Manual Chapter 0516, ,
" Systematic Assessment of Licensee Performance." The guidance and- :
evaluation criteria are summarized in Section III of this report. The
Board's findings and recommendations were forwarded to the NRC Regional
Administrator for approval and. issuance.
This report is the NRC's assessment of the licensee's safety performance '
at the Fort Calhoun Station for the period May 1, 1989, through April 30,
1990.

II. SUMMARY OF RESULTS-
Overview
The licensee'.s performance during this assessment period indicated
increased management involvement in and attention to the safe operation of
the facility. The evaluation of.the safety assessment / quality verification
functional area-indicated that senior management oversight and involvement
was readily evident, and emphasized, tl. rough the continuation of the
safety enhancement-program. Actions taken thus far have generally
increased the level of personne1' performance in all areas related to safe
plant operation. Effective implementation of the programs should continue
to increase'the performance in each functional area.
Improved performance was specifically noted in the functional areas of
plant operations, maintenance / surveillance. and security. .In the
functional area of radiological controls, strong management oversight was
evident,'as' indicated by the implementation of comprehensive programs that
address the elements necessary to ensure a' high level of performance.
Continued inanagement attention is required in these areas to ensure that the
enhancement programs are fully and effectively completed.
'The:11censee's performance ratings are' summarized ~in the table below,

'On the basis of the NRC assessment, each functional area evaluated is
rated according to three performance categories. The definitions of these
performance categories are:
Category 1 - Licensee's management attention and involvement are readily
,
evident and place emphasis on superior performance of nuclear safety or
' safeguards-activities, with the resulting performance substantially
exceeding regulatory requirements. Licensee's resources are ample and
effectively used so that a high level of plant and personnel performance-
, 'is being' achieved. Reduced NRC attention may be appropriate.
Category.2 - Licensee's management attention to and involvement in-the
performance of' nuclear safety or safeguards activities is good. The
licensee has attained a level of performance above that needed to meet-
regulatory requirements. Licensee's resources are adequate and reasonably
allocated.so.that good plant and personnel performance is being achieved.
NRC attention ~ may be maintained at normal levels.
. Category 3 - Licensee's management attention to and involvement in the
performance of nuclear safety or safeguards activities are not sufficient.
The licensee's' performance does not significantly exceed that needed to
meet minimal regulatory requirements. Licensee resources appear to be
strained or not effectively used. NRC attention should be increased above
normal levels.
IV. PERFORMANCE ANALYSIS
A. Plant Operations
1. - Analysis
'Hiis > functional area consists of activities such as plant
startup, power operation, plant shutdown, and system lineups.
Thus,'it includes activities such as monitoring and logging
plant conditions, normal operations, response' to transient and
- off-normal conditions, manipulating the reactor and auxiliary
controls, plant-wide housekeeping, and control room
professionalism. Activities that support operations (e.g.,
training and requalification, evaluation of emergency and
abnormal operating procedures, and other similar areas)-are
assessed in'the other functional areas discussed in this report.
During this assessment period, the licensee minimized challenges
to safety systems as only one manual and no automatic reactor trips were experienced. The manual trip was appropriately
initiated by an operator because of an indicated high bearing
temperature on a reactor coolant pump. This noteworthy
performance continued a long trend, in that the licensee has
experienced only one automatic and two manual trips since
July 1984,

'
The licensee continued to maintain a very experienced and
'a
' knowledgeable group of licensed senior reactor operators (SR0s)
end reactor operators (R0s), as has been evident during past
performance assessments. The operations staffing level was
stable during this assessment period with a very small turnover
rate of licensed operators (2 SR0s and 1 RO). On-shift staffing-
- was maintained at a level that permitted the licensee to-
maintain a six-shift rotation, except for-vacation schedules
during the summer months. The excessive use of overtime in,the
operations department has-not been identified as a concern.
,*
The licensee maintained a comparably small licensed staff that
currently includes 27 individuals (14 on-shift and 13 staff
personnel) that hold an SRO license and 8 on-shift individuals
that hold an R0 license. This staffing level represents a net
decrease of 2 R0s when compared to the staffing 1 year ago. The
small size of the licensed staff has been discussed by NRC
f during the two previous assessment periods. Licensee's
management has. stated that they intend to increase the number of
licensed personnel, especially in operations, by providing
three candidates for the R0 examination in May 1990 and
five additional candidates in October 1990. The licensee
maintains.a practice of producing very small operator license
classes in spite of a high success rate for recent license
examinations.(100 percent initial examination pass rate for the
last 6 site visits). Licensed operators have.been transferred
q to other departments within the licensee's nuclear organization,
such as' outage planning, maintenance' planning, training,
simulator services, and quality assurance. The operations
expertise of these individuals has shown to have a positive
impact on.these organizations with respect to providing support
~
'
to the operations department.
The shift technical advisor (STA) program has provided a-
positive contribution to plant operations. The STAS function as
an integral part of the operations crew and are very involved in-
the day-to-day operation of the plant by providing technical
assistance to the shift supervisor. In addition to the STAS,
the systems engineers provided technical recommendations to the
,
shift supervisor when component or system anomalies occur that
potentially affect the operability of safety-related equipment.
The interface between the operations staff and the departments
that provide support to operations (e.g., health, physics,
maintenance, chemistry, and training) has been effective during
this assessment period. To minimize the impact on the operating
crews during the refueling outage, the licensee assigned an
outage coordinator to act as an interface between operations and
other departments. This approach was effective in minimizing
the impact on operations during this high activity period.

Licensed, on-shift _ operators exhibited a dedicated commitment 1
toward the performance of their duties and safe-plant operation.- l
. Control room professionalism and. decorum was evident during this i
p assessment period, _ Plant operators;(licensed and nonlicensed) I
maintained an awareness of plant conditions and work activities
being performed under their control. On a number of occasions',
.
!
$ during this. assessment period, operations personnel responded to_- J
h plant perturbations and prevented more significant problems'that.
'
L =may have caused challenges to safety-related systems. Examples
! include a' loss of shutdown cooling due-to the loss of offsite-
L power and a: partial loss of component cooling water flow at full .

i Preplanning of activities affecting plant operations was ;
L apparent as evidenced during the removal of the 161-kV offsite 1
L power supply,.one of the two offsite. power grids, for preventive
(f maintenance. -Actions were taken to ensure that the onsite and

L maintenance or:other activities. However, the same conservative' ,
approach was not exhibited.toward shutdown cooling operations l

( generator,-for supplying power to the shutdown cooling pumps.
L In.this configuration, the electrical system was potentially- 1
n vulnerable to a single failure.

L failure to comply with the zlimiting conditions for -
l
operation (LCO) specified by the Technical Specifications (TS); l
t neither occurrence resulted in a degradation of safe plant ~
l operation. The events-involved the-failure to reduce. plant 'l
L power when two r'eactor protection system channels were declared j
, ' inoperable, and the failure to return the isolation valves' S
l properly for a component cooling water heat exchanger to; service 1
L
'
following maintenance activities. The first event resulted from- ,
inadequate. directions from plant management, and the second 4
,
event resulted from an-oversight by a nonlicensed individual. A l
l
review indicated that these events were isolated cases. ~I
A number of issues were identified during activities related to
the licensee's reconstitution of the plant design basis,
self-initiated reviews, and inspections performed by NRC
personnel. It appeared that management generally took a i
conservative approach when addressing problems of equipment and I
component operability. Some isolated cases were-identified, ?
early in the assessment period, where management exhibited a J
reluctance toward timely determination of equipment operability. l
In the'latter part of the period, operability determinations '
appeared to be conservative. j

I
o .
identified concerns in the areas of operations. personnel using -i
11 * and following procedures,. plant personnel entering the control- q
board area in the control room'for no obvious reason, and i
infrequent tours of the operating spaces by senior plant
,
management. The licensee addressed the first two concerns; lj
-however, management (except for radiological protection
'
l<
L -personnel) infrequently. toured the plant operating spaces other
than'the control room. The licensee took actions to increase
the frequency-of plant tours prior to the end of this assessment
,
period. Shift supervisors,'throughout this assessment period, ;
L . routinely toured the plant operating spaces to verify.that
equipment was operating satisfactorily.
l The licensee has made significant progress with upgrading plant
I
housekeeping, labeling, and appearance. The licensee's program 'l
for installing new valve and component labels has improved the '
!
operator's capability for. equipment identification. Color j
coding and labeling of system piping and painting of the plant
operating spaces (approximately'75 percent complete) has
I:
'
-significantly contributed to enhanced operations and the overall
plant appearance.
Overall, it appeared that the operations' staff. conservatively
p operated the p.lant to ensure that the health and safety of the
,
'
public were' properly protected. The. operations' staff
demonstr'ated their abilities to handle plant perturbations and 's
events. Weaknesses _with plant management's oversight of the :
operations area and 'a number of problems and concerns were '
identified to which the licensee proviend timely resolution and
took actions to prevent recurrence. j

'
B. Radiological Controls
1. Analysis
The assessment of this functional area consistsauf activities
related to occupational radiation protection, radioactive waste
management, radiological effluent control and monitoring,.
radiological environmental monitoring, water chemistry controls,
radiochemistry and water chemistry confirmatory measurements,
and' transportation of radioactive materials.
The radiation protection program inspections indicated that the
a licensee had implemented a high quality radiation protection
program. Some minor weaknesses were identified. One
NRC-identified violation occurred in September 1989 and involved
the failure to survey visitors leaving-the site. A-
licensee-identified violation was noted'in December 1989 and-
involved the failure to provide continuous health physics
coverage for a worker in _ a very high ' radiation area, and another
q; in March 1990 that involved the failure of a security guard to
follow established radiation protection procedures during entry
into a high radiation area. The licensee took prompt and
effective corrective actions and the violations were not an
indication of programmatic breakdowns.
The licensee mcde significant. improvements in the radiation
protection area during the last part of the previous assessment
period and continued to make additional improvements'during this
assessment period. These improvements included items such as
staffing, procedures, equipment and instrumentation,
coordination with other departments, training, and
self-identification of problem areas.
The staffing level in the radiation protection department
increased from 22 to 54 personnel during the previous assessment
period, and this level was maintained during this assessment
y ,
, .y w =
3,-
-10-
period. The' licensee only used contract radiation protection
personnel during outages and relied on the permanent staff
during routine operations. Within the current staffing level,
three new supervisor positions were authorized and filled. Each
individual selected for the supervisor positions holds a Masters
degree in health physics or nuclear engineering, along with
several years of applied health physics experience. The
licensee experienced a low turnover rate in_the radiation
protection department, as only two individuals have left the
department _since 1988.
.
The licensee implemented a comprehensive training program for
i
the rubiation protection staff-at both the technical level and
for professionals and supervisors. An effective program was in
. place'for the evaluation, screening, and-training of contract
radiation-protection technicians that were. brought on site
during outage activities. The licensee demonstrated initiative
to increase the technical expertise in the radiation protection
department in that_about 50 percent of the licensee's radiation
protection technicians have been certified by the National
'
Registry of Radiation Protection Technologists.
A high level of cooperation was achieved between the radiation
protection department and other departments-such as operations
and maintenance. However, one area, self-identified by the
licensee, was noted where the plant staff (nonradiation
protection department personnel), on two occasions, did not ,
follow established radiation control procedures. To reduce the
numbers of radiological occurrences, it appeared that department
supervisors needed to increase the emphasis for the plant
personnel compliance with radiation protection procedures.
The licensee completed construction of new facilities for access
. control into the radiation controlled area, office and work
areas for the' health physics and chemistry staff, and clothing
change areas for radiation workers. These new facilities were
completed just before the 1990 refueling outage and some final
arrangements remained to be completed such as personnel flow
paths and work stations at the access control point.
Improvements were made in the as-low-as-reasonably-
achievable-(ALARA) area since the previous assessment. Strong.
support for the ALARA program was demonstrated by the formation
of an ALARA executive committee that is chaired by the senior
vice president, and includes representatives from various
corporate divisions, the plant manager, and the supervisor,
radiation protection. Improvements were also noted in ALARA
activities such as the technical evaluation of ALARA work,
processing of ALARA packages, purchase of video equipment, and
better coordination between the ALARA group and other
departments.

The person-rem for 1989 was approximately 93; however, this
period did not involve a refueling outage. The annual average
person-rem for 1986 through 1989 was-208, as compared to a
national, average of approximately 300 person-rem. This low
person-rem was an indication of-an effective program for the
control of external exposure. The licensee established a
y conservative, 250 person-rem goal for the 1990 refueling outage.
'As of April 30, 1990, 214 person-rem had been expended and it
appeared that the outage would be completed under the
established goal. The licensee set a conservative personnel
E skin _-contamination goal of 23 for 1990,. but 36 events had
occurred as of late March 1990.
'
Management oversight was evident by the performance of
comprehensive audits and surveillances, and progress in the area
of self-assessment. The 1990 audit of the radiation protection
program included an auditor in the quality assurance (QA)
organization with several years of experience as a senior
radiation protection technician, along with a consultant that
"
also had.several years of radiation protection experience. The
audit report included verification that work was performed in
accordance with established procedures and,also included
suggestions concerning program improvement items. The responses
to the audit findings by the radiation protection department
were made in a timely manner and indicated a good understanding
of the technical issues. Except for some ongoing revision of
. procedures, the licensee completed work on approximately.
375 improvement items identified as part of the radiation
protection enhancement program.
'
, c 'The radioactive waste management and-radioactive effluent
f control and monitoring programs were inspected and no violations
were-identified. An effective liquid and gaseous < release permit
program was established. No: problems'were identified concerning
staffing, training, or qualifications of the personnel
1 responsible for operating the radwaste systems. The licensee
>
1mplemented a radwaste management program that demonstrated
compliance with the Radiological Effluent. Technical
>
Specifications and the Offsite Dose Calculation Manual.
The radiological environmental monitoring program was inspected
'
and no significant problems were identified. Regulatory
requirements were met regarding sample collection, analyses, and
'
resulting dose calculations. Well qualified personnel, with at
'least 10 years of experience, were assigned to implement the
environmental monitoring program. However, a formal training
program had not been established for personnel assigned to this
group.
The radiochemistry and water chemistry programs were inspected,
no problem areas were identified, and continued improvements

were noted in this area. The staffing level in the- ,
radiochemistry and water chemistry remained at 19 positions, the
same number as during the previous assessnient period. Four new ,
supervisor positions were authorized within the existing staf# .
organization. Management oversight included comprehensive QA !
audits.
New chemistry laboratory and radiochemistry counting facilities
were constructed and scheduled to be in use by the end of 1990.- 3
-
Vendor recommendations and EPRI guidelines for primary and :
"
' secondary water- chemistry parameters were incorporated into the
station chemistry procedures and were being followed. . Water ,
'
, chemistry and radiochemistry confirmatory comparison measurements
were performed. The radiochemistry confirmatory results showed ,
98 percent agreement, which was consistent with the 97 percent 1
agreement obtained during-the previous assessment. Water 1
-
chemistry confirmatory measurements indicated 97 percent
agreement, which was an improvement over the 88 percent agreement :
noted during the previous assessment, The confirmatory
measurement results indicated that the licensee's performance
was above the industry average in this area. The licensee made
improvements-in the quality control (QC) araa, including the use '
of QC charts to trend daily analyses of chemical parameters and !
reactor coolant and secondary water quality'results. 'I
The transportation of radioactive materials and solid radwaste
programs were inspected and no violations were identified. The
licensee completed-construction of a new solid radwaste ,
processing and transportation facility, which is scheduled to be
. fully operational in 1990. The 1icensee established .
implementing procedures that addressed waste classification and ,
characterization,' procurement and selection of packages,
preparation of packages for shipment, and delivery of the
completed packages to the carrier. The staffing level-assigned
to handle solid radwaste and transportation activities was
satisfactory. 'It was noted that the most recent QA audit of the ,r
solid radwaste and trarfsportation area, conducted in
November 1988, did not include transportation activities.
Overall, the licensee made progress during the previous
assessment period to improve performance in the radiological
controls area and this effort carried over into this assessment
period. Improvements made in the radiation protection and
chemistry / radiochemistry areas were-particularly noteworthy.
Strong management oversight of the activities in this functional ,
area was evident.

either diagnostic, predictive, preventive, or corrective
maintenance of plant structures, systems, and components;
procurement, control,~and storage of components, including
qualification controls; installation of plant modifications; and
. maintenance of the plant. physical condition. - It also includes I

inspection and testing activities.
"
This area was inspected on a routine basis by the resident
inspectors and-periodically by regional inspectors. A special
inspection was performed in the area of systems entry

The licensee has maintained a stable and well-qualified
maintenance work force with little turnover. .The staffing level
+
in the-instrumentation and control (I&C) area was a concern
identified in the previous SALP report. . The licensee's current
full-time I&C staffing level has been increased to 29 employees
(24 licensee and 5 contractor personnel) and appears to be
satisfactory.

of the crafts has compensated for marginally acceptable ;
'

,
The licensee has implemented a good maintenance program as
e evidenced, in part, by all equipment functioning properly during
engineered safeguards actuations, and no plant shutdowns have '
resulted from equipment maintenance problems. The operations ,
, department . identifies equipment needing maintenance attention to - <
the maintenance department each morning at the plan-of-the-day-
meeting. This interface has resulted in prompt attention to the
C * repair of safety-related equipment. '
, The SERT was conducted in the areas of design changes, temporary .1
alterations, and maintenance activities. The 3ERT inspection
determined that planned retesting of structures, systems, and-
components, that have been modified or subjected to maintenance,
properly verified equipment operability and ensured that the j
design basis was met. The licensee has a strong program for i
determining required retests and for the identification of the 1
-
appropriate retest method. The licensee's program for
development of procedures and performance of these procedures
for retest of structures, components, and systems, following
plant modification and maintenance activities, was.found to be
. satisfactory. A weakness'was identified in the assignment of.
o review responsibilities to ensure that correct retests were
included in postmaintenance and temporary modification work
packages. The licensee strengthened this area by administrative 1

- Systems. engineering developed and performed, during -this
assessment. period, comprehensive raw water (RW) system testing-
, that demonstrated that pump and heat exchanger performance had
degraded from the original design basis assumptions. With the
implementation of administrative controls ,the.RW system
remained operational and met.the design basis. . A reactive
inspection.was conducted to review the test results and
'
operability status of the RW system.. The inspection indicated
that the-four RW pumps had become degraded as a result of
deficient preventive maintenance, system testing, and erosion of
9 :' the pump bell housing because of pumping silt laden Missouri ,
river water. System engineering's performance in developing
"
integrated testing procedures to demonstrate F 2er system
performance was noteworthy.

, Inspections were performed in the area of inservice
inspection (ISI) and inservice testing (IST) and included the
surveillance, visual inspection, repair, and testing of
snubbers. Implementation of the IST program' upgrade: appeared to
be consistent with the licensee's committed schedule.
Surveil. lance testing of pumps and valves was consistent with the
requirements of Section XI to the ASME Code and the criteria
, outlined;in NRC Generic Letter 89-04. The ISI and snubber.
programs contained sufficiently detailed procedures to govern-
the work, provided easily retrievable records, and had'
sufficient qualified personnel. Management involvement in these
areas-was evident. An exception to this performance was=noted:
during. followup of the turbine-driven auxiliary feedwater- pump
1 event, as i discussed in'the engineering / technical support '
L functional area.
.The systems engineering organization provided field oversight
activities for equipment and component maintenance. The
.
'
presence of the engineers provided for the timely resolution of.
y technical issues that were identified.during maintenance
activities to minimize equipment down time.
l -In the last SALP report, concerns were identified with
- administrative controls of maintenance work orders, predictive ,
and preventive maintenance programs not=being fully implemented,
independent review of core physics testing data, and procedural l
compliance by maintenance personnel. The licensee has taken.

by the Safety Enhancement Program to address the ,redictive and
p, preventive maintenance programs.and are currently scheduled to
p1 be: completed by the end of 1990. ]
u
In the. area of surveillance, tests were being scheduleJ and-
performed as required by the TS. During an inspection, it'was 1
s noted that the- systems engineers had unilateral authority to j
H ' waive procedural requirements, and justification for waiving- j
"
procedural steps'and' acceptance criteria may not always be ,
l, given. Although no examples were identified where testing q
'
requirements were inappropriately waived, the inspector was j
l concerned that. the existence of this authority could result in-
unauthorized changes to procedures. The licensee addressed this
, concern by-providing guidance in a revised administrative
l procedure,

Overall, it' appeared-that the= licensee has initiated programs to
strengthen the_ maintenance area by upgrading the IST program,
addressing the technical adequacy of procedures, and initiation-
of preventive and predictive maintenance activities. The
staffing, especially in the I&C area, has been increased to a
satisfactory level. A surveillance program has been implemented
that ensures testing is performed in a timely manner.

1. Analysis
This functional area includes activities related to the
establishment and implementation of the emergency plan and
implementing procedures, licensee performance-during exercises-
and actual events that test the emergency plan, and interactions -
c' '
with onsite and offsite emergency response organizations during-
q exercises and actual events.
During this assessment period, region-based and NRC contract
inspectors conducted two emergency preparedness inspections.
The first inspection consisted of the observation and evaluation
of the annual emergency response exercise. The second

inspection-involved a review of the operational status of the
~
emergency preparedness program. No actual ~ events occurred
during this assessment period.
During the July 1989 emergency response exercise, the licensee's
- overall response was determined to be acceptable. The. control
room and technical support center staffs properly detected,-
classified, and declared emergencies, and made prompt
notifications to offsite agencies. -Although the,11censee's
overall performance during the course of the exercise
demonstrated an acceptable licensee proficiency to protect the
health and safety of the public, concerns were. raised by NRC
~
regardingspecificissues. One of the concerns involved the
licensee s over staffing of emergency facilities.with extraneous
personnel. Also, NRC expressed concern that the licensee's
staff had not been able to ascertain the hypothetical source of
the containment radiation leak and that licensee's management
failed lto devote an acceptable level of attention to the offsite
radiological consequences associated with the plume.
- An exercise weakness was Jentified with poor coordination,
'
, direction, and technical support provided to the control room
. staff by the technical support center staff. A similar weakness
i involved the lack of coordination with the operational. support
center response. Three of the other exercise weaknesses
,
involved, to some extent, repeated aspects from the=two prior
exercises. A significant, repeated weakness involved the
licensee's inability to demonstrate personnel accountability.
within-30 minutes. Scenario problems were found to be an
exercise weakness due to the_ inadvertent prompting of a player
by a-controller, which was a repeat-finding. Also, simulation
detracted from the extent of free play and, hence, diminished the
'
realism of the scenario.
Following the exercise, the licensee conducted a self-critique
and was able to appropriately identify and characterize a number
of exercise weaknesses, improvement items, and examples of good
performance. Several of these findings coincided with those of
the NRC observers.
An inspection of the operational status of the emergency
preparedness program identified weaknesses with the training of
.' "! emergency response personnel responsible for performing early
dose assessments from the control room. As a result of this
finding, the licensee made a prompt commitment to simplify the
dose assessment procedure and to retrain responsible users to
ensure that accurate and timely dose assessments could be made
from the control room. The licensee completed these corrective
actions prior to the end of i.his assessment period.

It was noted that some aspects of the emergency preparedness
program met all requirements and were considered strengths.
Emergency facilities, equipment, and instrumentation was
maintained in a good state.of readiness. Aside from control
room dose assessment, the knowledge and performance of the
duties of emergency-response personnel interviewed were good.
The licensee implemented an aggressive drill sched:le and
condut:ted-the drills in an'ef fective manner. Corporate
management involvement was' apparent in various aspects of the
implementation of the emergency preparedness program.
The' licensee initiated changes to the emergency-preparedness
program to implement significant improvements in the future.
Organizational changes were made to upgrade the position of +
supervisor, emergency planning such that this individual repo"ts
directly-.to the division manager, nuclear services. Additiou i
. technical-staff positions were added to the-emergency plannin;
and-training staffs. In addition, duties of certain emergency
response -positions have been proportioned to enhance response
capabilities.
~A major effort to upgrade the effectiveness of the emergency
plan implementing procedures was initiated, primarily through
contract resources, to improve their useability. -The licensee
n' has.also initiated an effort to redirect the-training in-
emergency preparedness toward a performance-oriented approach-
that will better prepare emergency-response personnel to perform
assigned functic ns during an emergency.
An effective QA pr) gram was implemented in the area of emergency
preparedness. . Indapendent audits met requirements, were well
coordinated and planned, and utilized satisfactory resources and
personnel. Audit findings.were properly characterized and
corrected. The licensee increased the number and frequency of
emergency preparedness-surveillances and made use:of. functional
-area experts in performing QA audits and surveillances.
Overall, the' licensee has initiated efforts to upgrade the
emergency preparedness program; including the emergency plan,
the emergency plan implementing procedures, and the staffing and
organizational reporting of the emergency planning staff. While
NRC recognizes this effort as a significant move toward
strengthening the licensee's emergency preparedness program,
4 there has not been sufficient timt for NRC to fully assess the
impact of these changes.

E. Security
'1. Analysis
i
The assessment of this functional area includes activities that 1
- ensure the security of the plant, including all aspects of
- access control, security checks, safeguards, and
fitness-for-duty activities and controls.
During this assessment period,.this area was routinely reviewed
by the resident inspectors;and. periodically by region-based
physical security -specialists.
'
Throughout the majority of this assessment period, the licensee
was' involved in implementing.a major upgrade'of the entire !
physical. security program. The upgrade program,{ completed o_n l
March 31, 1990g was-a well-designed effort that'was instituted
as a result of NRC and licensee-identified findings of
programmatic deficiencies during_ previous assessment periods,
c' The licensee now has a redesigned, closed-circuit
television 4 (CCTV) perimeter surveillance system, protected and
vital area intrusion detection systems (IDS),~and a computer I
1
support system for the CCTV and IDS systems. The licensee l
currently plans some minor additions in the areas of protected _
_
l l
area access control of packages and vital area access control of
personnel.
1
In September.1989 the licensee decided to establish a unified '
proprietary security officer force instead of utilizing a mixed l
force of contract and proprietary security officers. Because of
the transition and the uncertainties as to which contract
!. security officers would be retained, the licensee experienced
l some marginal personnel performance. Personnel errors resulting- i
l from excessive use of overtime for required compensatory
ll

g i
measures contributed to this problem. In addition, management
n has not been accessible to the security force members to
alleviate.the officers' concerns about the restructuring of the
security force. Consequently, security-officer morale has been
low,_some officers have exhibited a poor attitude, and, in some
instances, job performance has been adversely affected.
The?1icensee has made adjustments to improve security officer
,
-morale and performance. Positive adjustments include the
recognition of the need to complete the transition from contract
7to proprietary security officer force as soon as possible,
.providing new uniforms for security officers..and increasing
,
security officer training. The nuclear security officer
training program.has been restructured and an acceptable number
of personnel.has been assigned to supervise the' program.
-Two issues confronting the licensee during this assessment
period, because of the upgrade program, involved proficiency
training for central / secondary alarm station (CSS) operators.and
. performance-based contingency training. For CSS operators to
achieve proficiency; formal, on-the-job training with crucial
task testing was necessary. Unfortunately, this effort was
' impeded by delays in the installation of other equipment.
Consequently, alarm station operators were uncomfortable with-
.their experience' level on the CSS. As a result of the extensive
use of compensatory measures associated with the upgrade
program', the licensee has not yet been able to implement the.
performance-based contingency training that is a part of their
- upgrade program initiatives.
During this assessment period, the following violations occurr'ed,
some-of which-were self-identified by the licensee (including
the two significant-violations): failure.to log / report certain
security events; some access searches were inadequate and'
consequently allowed a handgun and ammunition to enter the
warehouse within the protected area (Severity Level III
' violation), and allowed a food stuffs. van to enter the protected
area without a proper search; on occasions, the protection of
safeguards'information was inadequate (. Severity Level III
violation);.an on post, sleeping security officer was found and
a problem was identified with the inability to post out; a
problem was found with assessment aids due to CCTV and perimeter
IDS electronic misadjustments; and inadequate control of a vital
area keys was identified. The licensee self-identified
m, violations were cited because the individual violations were
. considered significant events, because of the need to improve
individual performance, or because the violations were repetitive.
In general, the licensee's final corrective actions were prompt
and effective.

F. Engineering / Technical Support
1. Analysis
The purpose of this functional area is to address the adequacy
of technical and engineering support for all plant activities.
It includes all licensee activities associated with the design
,
of plant modifications;-engineering and technical support for
'
operations, outages, maintenance, testing, surveillance, and
procurement activities; and training.
.This functional- area was inspected on an ongoing basis by the
resident inspectors, periodically by region-based personnel, and
by the, probability risk assessment (PRA) team from Region IV.
The engineering organization has experienced a significant
transition, from one relying extensively on contractors, to an
,
.orgutization with a substantial in-house engineering capability.
This has resulted in an increase in the staffing levels in the
onsite and corporate engineering organizations.
Early in this assessment period, it was discovered that the
lice 6see had not included, in the group of safety-related
procedures to be upgraded, the alarm response, station
electrical system (includint safety-related electrical
distribution systems), main steam system, and main feedwater
system operating procedures. The licensee corrected the scope
of th'*- -f fort to include those procedures in the above
grew 4 . that had a potential safety impact on the operation of
the plant.
The abnormal operating procedures were in the process of being
upgraded under a Safety Enhancement Program effort. However,
tne abnormal operating procedure upgrade was not included in the
w' iter's guide issued for other safety-related procedures, and
the scope of the abnormal operating procedures had not included
the loss or degradation of most of the safety-related ac- and
de-electrical distribution systems.
As discussed above, and in other functional areas, the licensee
encountered problems with the technical content of safety-related
procedures. To address this concern, the licensee is in the
process of revising the technical content of procedures through
implementation of the procedures upgrade program contained in
the Safety Enhancement Program. In the interim, the licensee is
self-identifying procedure implementat W issues. This program
is currently on schedule and is expected to be completed by the
end of 1990.
An inspection in the control of special processes noted that the
licensee, through its procedures, welding manual, and quaiity
1

-23-
control manual, provided, for the most part, comprehensive
instructions for the control of special processes. However, two I
examples were identified for the failure to provide adequate !
instructions for controlling heat input-within the proper range, j
and failure to qualify the full range of material thickness !
specified in the welding procedure specification. Also, as a
welding program enhancement, the licensee committed to correlate I
the settings on the welding machines to actual welding amperage !
before making safety-related welds.
!
A special, announced team inspection in'the area of PRA was
performed. This inspection covered the critical components of ;
the plant and the operational activities relating to dominant '
l
accident sequences developed by a generic-based assessment. The
i generic PRA study identified the important systems, components, ,
I and activities that could contribute significantly to core melt
l accident sequences or mitigate the consequences of such events. ;
l The NA inspection team concluded that the emergency operating i
,
procedures, when used by experienced and trained operators, '
l provided an acceptable level of direction to mitigate the
l consequences of an accident. The team also concluded that the
i risk-important systems and components were generally tested and
l maintained commensurate with their importance to risk.
l The PRA team identified violations that involved inadequate
l emergency and abnormal operating prucedures, and a licensee-
l identified failure to have an adequate design control program
l for electrical circuit fuses. An NRC-identified deviation
i involved the failure to conduct an emergency operating procedure
l_ validation as committed to in a licensee submittal to NRC,
l- Other items of concern from this inspection included the lack of
I a' fuse / breaker coordination study, the lack of a fuse control
program, and the lack of a stroke test for the power-operated
l- relief valves. These items of concern were indicative of '
weaknesses in the licensee's design control program.
The licensee continued to show improvement in other areas of the
design change control program. Several inspections were
conducted that involved the review of the preparation of design
changes. The reviews confirmed that modification packages
continue to be complete, concise, and contained the appropriate
elements.
1
Concerns were previously identified by NRC with the licensee's
l capability to adequately resolve technical issues that are
identified during operation of the f acility. To address these
concerns,.the lisensee established the systems engineering
organization. This engineering group has proven to be a
l
valuable asset in the resolution of problems. The systems
engineers are involved in the day-to-day activities related to
the performance of the surveillance and maintenance functions,
. . #.c o !

'
and the trending of the results of these functions. This aspect
of the systems engineering effort has,provided technical :
expertise in the field for early identification of component and l
equipment problems. The contribution of the systems engineering l
organization toward overall plant safety was viewed as a
~
strength.
At the end of.this assessment period, the plant was in a !
'
refueling outage. Activities performed during the outage were
completed satisfactorily. Operations personnel removed and !
replaced all fuel assembites in the reactor vessel without '
incident. The performance of the integrated leak rate test was
completed in accordance with the appropriate requirements.
Performance of eddy-current testing indicated that no steam
generator tubes required plugging. This was the third ,
consecutive outage where no tubes were plugged and the results ,
were attributed to the strict secondary water chemistry program
maintained by the licensee.
l
The licensee has completed the issuance of the design basis !
documents for plant systems. Through this effort, the licensee I
identified instances where components and systems did not comply
o with the design basis requirements stated in the Updated Safety 1
Analysis Report. The licensee's engineering organizations
'
l
provided timely resolution of the identified problems. This d
t effort was identified as a strength.
1
i
During several NRC inspections, design-related problems were
identified. A review of the leak-rate testing of containment
isolation valves identified two penetration labeling errors and )
incorrect valve position labeling on piping and instrumentation 1
drawings. An inspection'of the implementation of commitments ,
made relative to Regulatory Guide 1.97 " Instrumentation For :
l
Light-Water-Cooled Nuclear Power Plants to Assess Plant and
l Environs Conditions During and Following an Accident," l
l identified problems with design documents. The inspectors i
experienced significant difficulty in extracting required
l information from design documentation. Licensee personnel ,
'
acknowledged these problems and indicated that in-house efforts
had been initiated to improve the drawing quality and
usefulness, and the computer data base content and accuracy. q
l
Inspections performed of the instrumentation calibration program
L identified violations that involved inadequate calibration of i
instruments utilized for postaccident monitoring and inadequate !
, environmental qualification of an instrument channel.
During a test of the turbine-driven auxiliary feedwater pump,
the pump failed to rs: pond to manually injected air signals to
'
i
l- the pnuematic-hydralic speed governor. The licensee determined
that the pump may not have been operable prior to the test
I
l i
l'
t
.. f,e
.

because of the failed speed governor components. The licensee's
response to this problem was deemed appropriate; however,
subsequent followup by an inspector determined that the pump had
been inoperable over an extended period because of deficient
testing, maintenance, and control system calibration. The
licensee's actions were aggressive in resolving the programmatic
and technical deficiencies in this instance.
Prior to the establishment of a formal procurement program for
commercial grade items-in 1988, the licensee experienced
deficiencies in traceability, establishment of critical
characteristics, insufficient in vection and testing, and vendor
qualification. Subsequent to th> astablishment of a formal
program, a significant reduction in these problems were noted.
The results of an inspection indicated that, while improvement
had occurred, more awareness for the need of an hdepth review
during the evaluation and dedication process was required.
Licensee management oversight of the training of licensed
operators and applicants for license improved. Management has
become more aggressive in identifying and correcting problems.
However, a recent self-identified f ailure to properly track
medical conditions for a licensed operator was a repeat of a
prior program failure. The licensee has implemented
comprehensive training programs for the technical, professional,
and maintenance staffs.
During this assessment period, the licensee installed a' control
room simulator to provide enhanced training for licensed
operators. T raining on the simulator commenced just prior to
the end of this assessment period. This training enhancement
was viewed as a positive contribution toward safe plant
operation.
Historically, the licensee has experienced difficulty with the
implementation of TS-required firewatch patrols. During this
assessment period, problems were identified in this area. To
address this continuing problem, the licensee has established a
group that is dedicated to the performance of fire patrols. The
security organization previously performed this function. Since
iLplementation of the dedicated group, no problems have been
identified.
On February 26, 1990, a loss of offsite power (LOOP) occurred
which resulted in a 2 minute loss of shutdown cooling. The LOOP
was caused due to the under-voltage trip relays not
automatically shedding the operating low pressure safety
injection (LPSI) pump. A special inspection was conducted
following the event. It was determined that during manual
operation of the LPSI pumps, the automatic load shed and
automatic ciesel generator output breaker closure features would

! be inhibited when an undervoltage event on vital electrical
buses occurred. The licensee analyzed the event and determined
that design of the electrical system complied with the plant
design basis and did not affect safe plant operation. As a
system enhancement, the licensee has decided to modify the
design in order for the emergency diesel generator to
automatically load in the event of the design basis accident and
a LOOP when a manually-loaded LPSI pump is operating. This
modification will be completed by the end of the 1991 refueling
outage.
In summary, several strengths, positive actions, and weaknesses
were identified during this assessment period. The licensee has
undertaken an extensive program for upgrading safety-related and
abnormal operating procedures, including technical content,
through the efforts of the Safety Enhancement Program. The
licensee continued to show improvement in the design change
control program as evidenced by the results from several
inspections conducted during this assessment period. Concerns
regarding the licensee's capability to adequately resolve
technical issues identified during plant operation were being
effectively addressed by the recently established systems
engineering group. During the recent refueling outage, the
eddy-current testing conducted on steam generator tubes
indicated that no tubes required plugging. This was the third
consecutive outage during which no tubes were plugged. The
results were attributed to a strict secondary water chemistry
program. The licensee's engineering organizations have provided
timely resolution to problems identified by the issuance of the
design basis documents for plant systems. Difficulties
experienced with the implementation of firewatch patrols appears
to be resolved by the establishment of a group dedicated to the
performance of fire patrols. Several items of concern
identified during a PRA inspection were indicative of weaknesses
in the design control program.
2. Performance Rating
The licensee is considered to be in Performance Category 2 in
this functional area.

G. Safety Assessment / Quality Verification
1. Analysis
The assessment of this functional area includes all licensee
review activities associated with the implementation of Itcensee
safety policies; licensee activities related to amendment,
exemption, and relief requests; response to NRC Generic Letters,
Bulletins, and Information Notices; and resolution of TMI items
and other regulatory initiatives. It also includes licensee's
activities related to resolution of safety issues,
10 CFR Part 50.59 reviews, 10 CFR Part 21 assessments, safety
committee and self-assessment activities, root cause analyses of
plant events,_use of feedback from plant QA/QC reviews, and
participation in self-improvement programs. It includes the
effectiveness of the licensee's quality verification function in
identifying and correcting substandard or anomalous performance,
in identifying precursors of potential problems, and in ,
monitoring the overall performance of the plant.
Inspection of licensee self-assessment activities identified an
overall effective performance by the Safety Audit and Review
Committee (SARC) and the Plant Review Committee (PRC). The-
licensee had identified and corrected the failure of a SARC
subcommittee to review recent plant modifications and their
associated safety evaluations. Additionally, the licensee
observed that neither group had performed any self-assessment
activity in regard to the safety-related procedure upgrade
effort. It was noted that PRC activities were not well
documented and it appeared that handling of action items could
be improved. It was also noted that one F,tC standing
subcommittee was not submitting the results of its reviews to
the PRC for approval. The licensee instituted immediate actions
to correct the cbserved PRC deficiencies.
To address a broad spectrum of concerns and weaknesses
previously identified by NRC, and an independent appraisal by a
licensee contractor of the FCS nuclear organizations, the
licensee developed and implemented the Safety Enhancement
Program. This program provides a comprehensive listing of
licensee actions related to safe plant operation and the
activities that support operations. Implementation of the
,, t.o
.
<
.
3
-28-
actions contained in the program has received a high level of
corporate and plant management attention and support. The
licensee has demonstrated positive steps toward improving their
overall performance by implementation of the items contained in
the Safety Enhancement Program. This overall improvement
indicates that the licensee is improving their capability to
provide management leadership and oversight of the diverse
elements related to the conservative operation of the FCS.
Although all items have not been completed, the effort to
complete the remaining open items is on schedule.
$atisfactory programs were found to be in place with respect to
implementation of the 10 CFR Part 21 review program and the
control of measuring and test equipment (M&TE). Positive
actions were observed.to have been taken by the licensee to
correct a prior weakness in regard to control of M&TE used by
the 1&C maintenance group.
The licensee implemented a training program for those
individuals invol u d in the preparation, review, and approval of
10 CFR Part 50.59 evaluations. Personnel completing the
training are the only individuals authorized to process
Part 50.59 evaluations. This approach has been a positive
contribution towards the licensee's satisfactory completion of
Part 50.59 evaluations.
A comprehensive corrective action program was established that
appropriately provides for identificatien, tracking, correction,
and trending of safety-related problems. The licensee was also
observed to have implemented surveillance programs to provide
additional oversight of inservice inspection contractors and
in process welding.
The licensee has established and implemented a Nuclear Safety
Review Group (NSRG), an independent organization that reviews
plant events and occurrences to determine the roat cause(s) and
recommend corrective actions. The establishment of the NSRG was
a licensee self-initiated action that parallels the independent
safety review group required by the TS for newly licensed
facilities. The NSRG has been fully staffed by experienced
individuals with diverse backgrounds, and is managed by an
individual that previously served as supervisor, operations.
The NSRG completed, during this assessment period, ten root
cause analysis reviews on plar.t events such as inadvertent
overflow of the spent fuel pool, failure of the turbine-driven
auxiliary feedwater pump speed controller, and the loss of
offsite power during the refueling outage. The reviews
performed by the NSRG have been comprehensive and have provided
the appropriate recommenJations for corrective actions to
prevent recurrence. The establishment and performance of the
NSRG was viewed as a strength.

The licensee has upgraded the staf fing of the QA organization by
the addition of experienced QC inspectors and technical auditors
with working experience in the areas of operations, health
physics, security, and chemistry. The staffing level in the QA
organization was satisfactory. In the previous SALP report, a
concern was identified with the performance of audits by QA.
The audits were noted to be compliance-based rather than
performance-based. The licensee has taken actions to address
this issue. A review of the licensee's audit program indicates
that performance-based audits are now being performed. As noted
in the discussions of the other functional areas, the licensee's
audit program has been comprehensive, thoroughly performed, and
corrective actions taken in response to audit findings were
appropriate and timely.
The licensee has established and issues, on a monthly basis, a
comprehensive set of performance indicators. These indicators
provide management with a tool that can be used for early
identification of adverse trends so that corrective measures can
be taken to reverse the trend. In addition, the QA organization
publishes a detailed quarterly trend report that summarizes the
results of their audits.
During this assessment period, eight license amendments were
issued. These amendments included incorporation of surveillance
and operability requirements for the citernate shutdown panel,
generic specifications incorporated into the TS, surveillances
and limiting conditions for operation for a contrci room
modification to alleviate air in-leakage, and some
administrative changes. In addition, safety evaluations were
issued that addressed TMI actions, Salem ATWS items, and actions
requesting reliefs from the ISI and IST programs.
The licensee's submittals, in general, indicated an acceptable
level of understanding of the technical issues from a safety
standpoint and acceptable approaches were used. However, in the
latter part of this assessment period, weaknesses were
identified in both the schedular aspects of the licensee's
submittals and fully addressing the requirements of the proposed
TS changes. Six submittals were required prior to th approval
of a license ameMment request for the boric acid heat tracing
system. This can be attributed to factors related to the
refueling outage, many ongoing actions being performed
siPtaneously, recent new employees joining the organization
(almost doubling the work force), and pressure to meet the
schedule. The licensee has incorporated chnges that should
rectify some of these problems.
The licensee's responsiveness to NRC Bulletins and Generic
Letters was timely and technically complete. Responses during
this assessment period included NRC Bulletins 88-03, " General

Electric HFA Relays"; 88-10, " Nonconforming Molded Case Circuit
Breakers"; and 89-03, " Potential Loss of Required Shutdown ,
Margin During Refueling." The licensee's response to_NRC '
Bulletin 88-10 had to be revised because four breakers, which
were to be replaced during the 1990 refueling outage, could not
be obtained from the vendor. The licensee indicated that these
breakers would be replaced during the 1991 outage and that a
justification for continued operation would be in place which
the NRC subsequently found acceptable. The responses to Generic :
'._
Letters included 89-06, " Safety Parameter Display System";
89-07, " Power Reactor Safeguards for Surface Vehicle Bombs"; :
89-08, " Erosion / Corrosion"; and 90-01, "NRC Regulatory Impact
Survey."

A review of the licensee event reports submitted to NRC
indicated that the reports described the major aspects of each !
event, including the causes of system failures that contributed-
to the event and the significant corrective actions taken or
planned to prevent recurrence.
Overall, the licensee's programs that provide for the assessment
and verification of activities related to the various aspects of- >
safe plant operation have received a high level of senior
management attention and involvement and have placed emphasis on
superior personnel performance. These programs provide a solid
basis for increased overall performance and the attendant
philosophy contained in the programs should be implemented
through all levels of the nuclear organization. These programs i
include self-identification of problems through the r
implementation of QA audits effective performance of the SARC,
and the root cause analyses performed by the NSRG. The actions i
implemented through the Safety Enhancement Program provided an
increased level of management oversight with respect to plant
operations. !
