I. INTRODUCTION
1. Purpose and Overview
The Systematic Assessment of Licensee Performance (SALP) is an integrated '
NRC staff effort to collect the available observations on a periodic
-basis and evaluate licensee performance based on those observations with
the objectives of improving the NRC Regulatory Program and licensee per-
formance.
The assessment period is April 1, 1984 through March 31, 1985. The prior
assessment period was December 1, 1982 through March 31, 1984. Signifi-
cant findings from prior assessments are discussed in the applicable
Performance Analysis (Section IV) functional areas'. Evaluation criteria
used during this assessment are discussed in Section II below. Each
criterion was applied using the " Attributes for Assessment of Licensee
Performance," contained in the NRC Manual Chapter 0516.

3. Background
Duquesne Light Company was issued a Construction Permit (CPPR-105) to
build Beaver Valley, Unit 2 (Docket No. 50-412) on May 3, 1974. The
Nuclear Steam Supply System (NSSS) is a 2660 MWt Westinghouse PWR with
three loops; the Architect / Engineer (A/E) is Stone and Webster. At the
end of this assessment period, fuel load is scheduled for April, 1987,
and the planned commercial operation date is December, 1987. Stone and
Webster Engineering estimated the construction at 85.3 percent complete
as of March 31, 1985, as compared to 77.5 percent complete at the end
of the last assessment period (March 31,1984).

a. Licensee Activities
The numbers of craft workers decreased slightly during the assess-
ment-period. On March 31,.1984, there were 2412 craft workers, ,
compared to 2338 craft workers on March 31, 1985; a decrease of:3
percent. -Second shift activity.was increased from 423 to 570 during
.this period. There is essentially no third shift activity. Weekend
-activity has decreased from an average 1746 manual and nonmanual
personnel to an average.of five manual personnel working on Satur-
days. The licensee's Quality Control Department staffing increased
from 281~to 361, an increase of 28 percent. Stone and Webster En-
gineering supervisory, engineering and administrative personnel on
site have increased 34 percent; from 485 to 650 people. The major-
ity of this increase was in the Engineering Department. Also not-
able was the assignment by Stone and Webster of a full-time Site
Project Manager and a Site Engineering Sponsor. Both of these
senior managers bring many years of nuclear. experience to the pro-
ject in key areas.
Reorganizational changes were made in the Duquesne Light Company .
Startup Group during the assessment period by combining the " Con-
struction Startup Group" (CSUG) and " Operations Startup Group" ,
(OS'JG) under one Startup Manager as the "Startup Group" (SVG). This
will eliminate the need for two independent turnovers as well as
combine all testing activities.
Additional safety-related equipment was completed and turned over
to Duquesne Light Department Startup Group. Thirty-eight (38) sub-
syster release packages that contain safety related items were
turned over. Included in these packages were major items such as
the 4160-volt-emergency buses, the 480-volt emergency buses and
substantial portions of the Service Water and Primary Component
Cooling Water Systems. See Functional Area 10 for additional de-
tails.
-During this assessment period, the major construction activities
included installation, welding,' examinations, hydrostatic testing
and flushing of the main steam, feedwater, large and small bore
piping and associated supports; heating, ventilation, and air con-
ditioning (HVAC) and fire protection systems were partially in-
stalled; pumps, motors, control panels, reactor coolant pumps and
motors, and safety-related storage tanks were installed and con-
nected. Electrical cable trays were installed, cable was pulled
and terminated; instrumentation lines and associated hardware were
partially installed. Painting / coating occurred throughout the site.
Insulation of tanks and pipes commenced during this assessment
period. The major-portion of safety related work on soils and
foundations was completed before this assessment period started.

To complete the cable pulling, approximately two million additional
feet remain to be pulled of the approximately 5.8 million feet total.
The contractor plans to pull 90 percent of the remaining cable dur-
ing the 1985 calendar year. The reactor coolant system hydrostatic
test is planned for May, 1986. Steam generator hydrostatic test
-of the secondary side is scheduled for January,1986. The initial
startup of the diesel generators is planned during 1985. The tur-
bine was put on turning gear in October, 1984.
b. Inspection Activities
A second resident inspector was assigned onsite effective October
7, 1984. Resident inspector activities involved accomplishment of
assigned inspection requirements including observation of work in
progress, follow-up of licensee events, reactive inspection and
evaluation of licensee responses to NRC identified concerns. In
addition, the resident inspector participated in a Construction Team
Inspection (CTI) conducted by NRC Region I.
Twenty-two inspections were performed during the assessment period;
nine independently by resident inspectors, twelve by region-based
specialist inspectors and one Construction Team Inspection performed
jointly by a resident inspector and region-based specialist inspec-
tors. There were 3917 hours0.0453 days <br />1.088 hours <br />0.00648 weeks <br />0.00149 months <br /> of inspection of which 1593 were by
the resident inspectors, 1207 were by region-based specialists and
the remainder was the CTI plus the inspection hours involved in
examinations of components using the Nondestructive Testing Mobile
Lab. The specialist inspection activities were in the following
areas: instrumentation installation, piping and pipe support in-
sta11ation, electrical cable installation, electrical separation
and termination, welding and welder qualifications, preoperational
L test and operational preparedness, and independent verification of
piping, structural, and support weldments. The CTI included cover-
, age of project management, engineering / construction interface,
4
quality assurance / quality control, piping and mechanical components,
and electrical / instrumentation work.
c. Licensing Activities
The Draft Safety Evaluation Report (SER) was issued March 1, 1984.
Final SER issuance is planned for April,1985. NRR and DLC Licens-
ing Division continued correspondence and meetings to resolve NRR
outstanding items. This included site visits made by NRR personnel
to observe the actual installed condition of the hardware. The
ACRS full committee hearing is scheduled for August, 1985.
.
Four amendments (Amendment 9) to the FSAR were issued during this
assessment period.

II. CRITERIA
The following criteria were used as applicable in evaluation of each func-
tional area:
1. Management involvement in assuring quality.
2. Approach to resolution of technical issues from a safety standpoint.
3. Responsiveness to NRC initiatives.
4. Enforcement history.
5. Reporting and analysis of 50.55(e) and Part 21 items.
6. Staffing (including management).
7. Training (effectiveness and qualification).
To provide consistent evaluation of licensee performance, attributes associ-
ated with each criterion and describing the characteristics applicable to
Category 1, 2, and 3 performance were applied as discussed in NRC Manual
Chapter 0516, Part II and Table 1.
Category 1: Reduced NRC attention may be appropriate. Licensee management
attention and involvement are aggressive and oriented toward nuclear safety;
licensee resources are ample and effectively used such that a high level of
performance'with respect to operational safety or construction is being
achieved.
Cateocry 2: NRC attention should be maintained at normal levels. Licensee
management attention and involvement are evident and are concerned with nuc-
~
lear safety; licensee resources are adequate and are reasonably effective such
that satisfactory performance with respect to operational safety or construc-
tion is being achieved.
Category 3: Both NRC and licensee attention should be increased. Licensee
management attention or involvement is acceptable and considers nuclear
safety, but weaknesses are evident; licensee resources appeared strained or
not effectively used such that minimally satisfactory performance with respect
to operational safety or construction is being achieved.
'
The SALP Board also assessed ea r functional area to compare the licensee's
performance during the last quarter of the assessment period to that during
the entire period in order to determine the recent trend for each functional
area. The trend categories used by the SALP Board are as follows:
Improving: Licensee performance has generally improved over the last quarter
of the current SALP assessment period. .
Consistent: Licensee performance has remained essentially constant over the
last quarter of the current SALP assessment period.
Declining: Licensee performance has generally declined over the last quarter
of the current SALP assessment period.

III. SUMMARY OF RESULTS
1. Overall Facility Evaluation
it Improvement was shown in all three areas that received low ratings
(Category 3) in the last SALP report; the licensee and their primary
contractor were responsive in addressing the weaknesses noted in that
assessment. Several initiatives implemented ~during this assessment
period were effective in improving performance in those weak areas, how-
ever, some lingering engineering / construction interface problems still
exist in the electrical / instrumentation area. An overall program for
resolution of electrical cable separation. problems now exists; satisfac-
tory progress is now being made in this area. Additional attention to
separation problems involving instrumentation tubing and internal panel
wiring is needed.
Satisfactory performance was achieved in each functional area, but prob-
lems within several areas need further attention if higher performance
levels are to be achieved.- These include better control over items being
reworked, day-to-day attention to in place storage to preclude past cyc-
lic performance in this area, assuring that recent actions to preclude
or provide for prompt: identification of QC inspection errors are effec- i
tive, and tightening the system completion / turnover process to reduce
- the high number of open items at turnover. Licenser. project management =
and startup programs are functional, but better defined organizational
responsibilities and control of system completion / turnover are needed.
Quality Assurance and Administrative Controls was evaluated as a separate
functional area in this SALP assessment period due to numerous organiza-
tion and senior management changes that occurred during this period.
Except for isolated cases of inspector error, the Quality Assurance /
Quality Control organization has been effective in assuring quality
through independent audits, daily inspection activities, and reinspec-
tion efforts. Licensee resolution and followup of deficiencies resulting
- from inspector errors were thorough and are now complete.

I V.- PERFORMANCE ANALYSES
1. Centainment and Other Safety-Related Structures' (1%)
a. Analysis '
During the~ prior assessment period, performance in this-functional
area was generally good. Problems were identified which involved
a failure to identify requirements for bolted connections of struc-
tural steel joints with long slotted holes and the lack of progress ;
in repairing containment electrical penetration welds.
All inspection coverage in this area was by the resident inspectors
during the current assessment period. It included the licensee's
activities to demonstrate that surface coatings in containment were
acceptable, verification that high strength bolts and nuts were used
in the construction of structural steel members, and the repairs
made on the containment electrical penetration welds. Although in-
spection coverage was limited, this Functional Area was rated during
this assessment in recognition of the licensee's thorough followup
on problems noted in the last SALP as well as in-response to an
allegation.
The bulk of all concrete was placed during previous assessment
periods, and during the previous assessment period, the batch plant
was disassembled and removed from the site. The miscellaneous con-
crete poured during this period was'obtained from offsite. The
major work remaining to be done in this functional area is the ;
closing of the cor.tainment construction opening: which is planned
for the fall of '985. ,
t.
'
. No problems were identified by the NRC during this assessment period.
The concerns expressed in the last SALP report regarding the slow '
progress being made on the required repairs to containment electri- ,
cal penetration welds have been satisfactorily resolved. During
this assessment period, all repairs were completed and reinspected
with minimal impact on construction.
To resolve an allegation that the NRC received from an outside
l . source, DLC performed extensive destructive tests on paint coatings i
inside containment to demonstrate acceptable coating adhesion and ;
, thickness. The licensee took the initiative and contracted a coat-
j. ing expert to destructively sample 187 areas where coatings were
l applied to assess installed conditions. All areas investigated were
l acceptable. This demonstrates a commitment to quality and a desire
'-
to work with the NRC to resolve safety concerns.
No 50.55(e) reports were issued in this functional area.

2. Piping Systems and Supports (27%)
a. -Analysis
- During the prio'r assessment period, there was a marked increase in
the number of deficiencies and errors noted in this functional area.
Many of:the protAems were attributed to deficiencies in basic docu--
p ments'such as drawings and specifications, and involved lack of
clarity, insufficient details, ambiguity, conflicting requirements,
- _ etc. . Problems ~fn this area were closely related to weaknesses in
the engineering / construction interface; a Category 3 rating was
assigned.
This area received frequent coverage by the resident inspectors,
during four inspections by region-based specialists, and was in-
cluded in the Construction Team Inspection (CTI) coverage. One of
the specialist inspections included the NDE van and actual tests
were performed on.several components. A high level of piping in-
'
- stallation has continued throughout the assessment period. The
'
,
majority of the large bore piping is installed; however, many of
[ .the associated supports are not. Small bore piping installation
is progressing satisfactorily.
_The licensee and constructor have been aggressively pursuing-and
-
correcting the root causes of problems identified in this area in
the last SALP. An action taken in the Engineering Department was
L the formation of an " Integrated Construction Support Group" (ICSG)
in November, 1984. The personnel are located in the Auxiliary
Building which allows construction direct access to the engineers. '
The group's function is to' perform " hands on resolution of con-
~
i
struction problems ~ associated _with the drawings or specifications."
This group has high visibility and accessibility to the construction
forces. It has strong licensee and constructor support and-although
E
it has been operational for only a short time, it appears to be
functioning very well~and eliminating many construction / engineering
l. problems where confusion previously existed.
!.
l Stone and Webster Engineer.ng also established a "Constructability
l Review Team (CRT) to review pipe support drawings and assure they
were precise and clear. The objective was to eliminate the issuance
of confusing information to. Quality Control'and Construction which
would then be.used during installation and inspection. This di-
rectly addresses a problem. area discussed in the last SALP report.
This team consisted of representatives from Schneider. Power Con-
struction and Engineering,' Stone and Webster Construction and Engi-
neering, and Duquesne Light Company Site-Quality Control. Since
this team's inception in June, 1984, it has been very effective in
eliminating confusion on drawings. The team decided shortly after
its formation to completely redraw all pipe rack support drawings.
Also,1 numerous changes were required on-individual pipe support

drawings. Many drawings were expanded from one sheet to two sheets
to provide clarity. The effectiveness of the CRT efforts, including
feedback ~to and training of design engineers, has been demonstrated
by the marked decrease in the percentage of drawings that are being
sent back for revision following CRT raview (from an initial rate
of approximately 50% to a 3-5% rate by the end of the assessment
period).
The " Engineering Confirmation Program" was implemented during this
period,_ partially because of past concerns identified by NRC. The
licensee's portion of this program was completed during this as-
sessment period. Stone and Webster plans to complete their part
of the program during 1985. Licensee management has shown strong
support for this program. The licensee is demonstrating through
implementation of this program, the acceptability and implementation
of specification and design criteria.
The licensee has placed greater emphasis on reducing the number of
first time rejects (i.e., construction presenting unacceptable
material to Quality Control), by emphasizing to the workers and
construction foremen the need for quality improvements during the
initial construction and installation of the hardware. This has
strong management support and resulted in a reduction of the amount
of rejected material. In parallel with these corrective actions,
the piping contractor replaced the Project Manager and Assistant
Project Manager effective January 1,1985. These actions are de-
signed to reduce the problems the contractor had been experiencing.
The above actions demonstrate considerable attention to past weak-
nesses in this area. To date, these efforts appear to have been
effective.
The licensee has implemented major reinspection programs to correct
discrepancies in the area of pipe supports and baseplates. (This
was also identified as a concern in the last SALP report.) Imple-
mentation also included numerous reinspections of supports due to
inspector error. (This item was reported to the NRC as a 50.55(e)
. item.) The reinspections and rework have, for the most part, been
!
completed.
1
i NRC has identified conc. erns in this area involving reworked items.
The contractor needs to' implement stricter controls when existing
QC inspection reports are nullified and when additional inspections
! are necessary when existing pipe supports are reworked or dismantled.
L Although the licensee has issued procedures to control this area,
implementation results have only been marginally effective. This
item was also the subject of a 10 CFR 50.55(e) report.

\

The number of croblems identified by NRC and other independent
audits involving pipe supports indicates some weaknesses in the
quality program in this area. However, when problems were identi-
fled, the licensee took-excellent corrective actions through in-
spections and rework to assure the product was constructed ade-
quately. For the inspector errors, the licensee has taken strong
punitive actions and/or retraining where necessary.
Hardware quality was assessed during this period through inspections
performed using the NDE Mobile Lab. Numerous welds and supports
were inspected to verify component workmanship and quality. These
sample inspections found acceptable weld quality and verified the
installed product is constructed to acceptable quality standards.
To demonstrate the acceptability of using a flexible ring to main-
tain minimum gap on socket welds (trade name Gap-0-Lets), the lic-
ensee had extensive analytical work and flow testing performed on
simulated welds. This data supported the licensee's position on
acceptability; it demonstrates the licensee's willingness to resolve
any NRC quality concerns even when significant additional efforts
are required.
A " Construction Team Inspection" (CTI) performed late in the SALP
period found no significant problems in this area and verified ac-
ceptable construction practices were established. The CTI and NDE
independent inspections also found that the licensee, constructor
and contractors have excellent record-keeping and retrieval capa-
bilities.
In summary, the licensee has implemented numerous management pro-
grams supplemented by reinspection to strengthen tho programmatic
weaknesses identified in the last SALP report. From a programmatic
standpoint, these appear to be strong corrective actions and should
be effective in eliminating these weaknesses. However, for several
of these actions, implementation has been too recent to demonstrate
overall effectiveness. Control of reworked items needs additional
management attention to be effective. The CTI inspections found
this area to be adequately controlled. Overall, the licensee and
contractor have shown positive results and improvements since the
last SALP. With implementation of these programs and continuing
strong management support of the new controls, continuing satisfac-
tory performance should be assured and furthe.r improvements should
be achievable.
b. Conclusion
Category 2, Improving. Licensee / contractor initiatives have been
responsive to past NRC concerns in this area.

3. Safety Related Components (15%)
a. Analysis
No significant problems were noted in this area during the prior
assessment period. Work on safety related components was found to
be well controlled; a Category I rating was assigned.
Most of the inspection activities in this~ area were by the resident
inspectors; there was one inspection by a region-based specialist.
The work activities in this area included connecting the main steam
- nd feedwater piping to the steam generators, final assembly and
trial fitting of the reactor vessel upper and lower internals, re-
work of the main steam isolation valves, installing the reactor
coolant pumps and motors, and completion of the site fabricated
storage tanks.
NRC found that good controls were in place for the large amount of
work involved in welding, repairs, and heat treatment of steam
generator piping connections; fitting and welding of the reactor
vessel upper and lower internals; repairs of the main steam isola-
tion valves; and installation of the reactor coolant pumps and
motors. Two violations were identified during this assessment
. period; (1) failure to follow procedure for disassembly of a valve;
and (2) liquid penetrant indications found on previously inspected
and accepted reactor vessel internals. The licensee is taking cor-
rective actions on these items. The liquid penetrant indication
was found to be superficial when cosmetic sanding was performed and
.
had no apparent effect on the structural adequacy of the reactor
vessel internals. Both cases appear to be isolated. However, bet-
ter controls on disassembly of components are warranted.
NRC found steel chips and other foreign material present on the in-
terior of the reactor vessel upper internals rod guides which indi-
cated a need to implement stronger controls on the fabrication and
installation of these critical components.
In summary, overall performance in this functional area is good.
The high performance levels noted in the previous SALP assessments
have been maintained except for isolated deficiencies.
b. Conclusion
Category 1, Consistent.

4. Support Systems (9%)
a. Analysis
No significant fabrication problems were identified in this area
during the last assessment period. The licensee and contractor had
good controls; a Category 1 rating was assigned.
This area was covered by the resident inspectors and during two in-
spections by region-based specialists. Installation of the heating,
ventilation and air conditioning (HVAC) and fire protection systems
continued throughout the assessment period. No violations were
..
identified.
Inspections were performed in several areas of HVAC installation
including vendor records and general construction. Limited inspec-
tions of records and procedures for fire protection systems were
performed. Good controls were found in each of these areas.
A 50.55(e) significant item was reported to the NRC. A Duquesne
Light Company Quality Assurance Audit identified that HVAC supports
failed to meet minimum weld sizes stated on the drawings. Investi-
gations performed by the licensee found the undersize welds were
missed primarily because of one inspector's errors. This indicates
some breakdown in the licensee's Quality Control Program; however,
the licensee's Quality Assurance Program was effective because their
internal audits discovered the deficiency. Management took neces-
sary punitive actions regarding the individual involved. In addi-
tion, management took good corrective actions by performing 100%
reinspection of the inspector's work and through sampling of other
inspectors' work. Overview inspections of new work as accepted by
'
QC were also implemented. These aggressive actions were effective
in restoring confidence in the quality of support welds.
In summary, the licensee and contractor have good controls in this
area. The licensee's identification and correction of problems
indicates overall good control of quality. The contractor has also
demonstrated good fabrication controls.
b. Conclusion
Category 1, Consistent.

5. Electrical Power Supply and Distribution (17%)
a. Analysis
Day to day construction and QC inspection activities were considered
to be under good control during the prior assessment period. How-
ever, the licensee / contractor had been very slow in developing and
implementing an approach that would meet cable separation commit-
ments and requirements so as to resolve widespread cable separation
problems. A Category 3 rating was assigned.
This area was covered by the resident inspectors, during six in-
spections by region-based specialists and by the CTI. Cable trays,
conduits, and cable continued to be installed throughout the as-
sessment period. The bulk of the remaining work involves cable
pulling and termination. Included in this area are cable support
activities (in trays and in free air) as well as wrapping cable for
fire protection, covering raceways with tray covers and other acti-
vities to meet the separation criteria required by Regulatory Guide
1.75.
One violation and one deviation were identified during this assess-
ment period. The violation involved failure to follow procedures
during cable pulling and inadequate controls for protection of cable
already installed. Exceeding cable bend radius, pulling cable with
nonconforming conditions on the cable, and damaging installed cable
because of sharp corners on tray side rails were examples cited in
this violation. These problems were attributed to lack of controls
in the interface between the Engineering, Quality Control and Con-
struction personnel regarding when cable pulling should be stopped
and/or started, timely issuance and disposition of nonconformance
and disposition reports, and written and/or verbal disposition by
Engineering. The deviation resulted from the licensee's failure
to fulfill commitments made to the NRC regarding controls on cable
overfill in raceways. Corrective actions regarding the deviation
have been taken and accepted by the NRC.
Other concerns were identified during this assessment period, many
of which represent lingering engineering / construction interface
problems similar to those discussed in the last SALP report. They
include:
--
Unsupported cable lengths in excess of specification which
could lead to support overloading and resultant cable damage
(denting). This issue now appears to be sufficiently clarified
to allow QC inspectors to perform inspections and identify
areas where additional supports are needed. In attempting to
resolve this issue, many conflicting requirements were pre-
sented to the NRC. The NRC's identification of these problems
and the constructor's failure to provide acceptable engineering
- * -
, ,
18
corrective actions at the outset of problem identification
indicates additional management attention is required to re-
solve technical issues as they arise in this area.
--
The retorquing of spring nuts, a problem identified by the
licensee. This a major problem which should have been avoided
with proper torque applied during installation. This was a
problem in the engineering area in failing to specify torque
4
requirements to the contractor for installation, consistent
with the spring nut manufacturer's recommendations,
i
--
The constructor's inability to provide satisfactory resolution
to the NRC's questions regarding consideration of side wall
pressure during pulling of cable. (Subsequent to the end of
the assessment period, the licensee was in the process of re-
vising cable pulling procedures and reviewing the acceptability
of existing pulled cable.)
--
NRC identified conflicting requirements between engineering
specifications and FSAR requirements regarding the identifica-
tion of cable runs from safety-related buses to non-Class 1E
loads. FSAR and specification changes were required to eli-
minate the confusion.
--
Other problems, such as the violation (see Functional Area
11) involving improper disposition of nonconforming condi-
tions on pull tension and bend radius, manual changes to en-
gineering cable pull tickets without design requirement con-
siderations and NRC concerns which involv:d the followup omis-
sion of shims on electrical supports, inacequate torquing of
anchor bolts used on electrical supports, inadequate control
of cable fills in raceways, tray-to-tray connections with use
of unqualified material, and lack of controls on storage of
coiled cable indicate weaknesses in the Engineering'and/or
Construction electrical discipline.
Many of these items have since been adequately resolved and in some
instances, reinspections to identify the need for rework are in
progress. The reinspection and/or rework of some of the other
items, such as retorquing the spring nuts, retorquing Hilti bolts
and inspection and installation of shims under baseplates is a con-
'
.
cern because of timeliness in commencing the reinspection. The plan
to inspect these items late in 1986 could create some accessibility
problems for Hilti bolts and baseplate shims. Also, further fabri-
cation and turnovers to DLC of these systems with existing known
nonconforming conditions is a concern because it creates the need
to perform construction rework on systems turned over to operations.
The last SALP identified that good corrective actions were being
taken on the majority of these items; however, since that time,
reinspections were stopped.

A' major area identified as a weakness in the last.SALP report re-
garding cable separation and compliance with Regulatory Guide'1.75
'has since received extensive management attention. Cable pulling-
was stopped by the-licensee until clear resolution and direction
was established. Stone and Webster Engineering established a pro-
~
gram to resolve all issues and systematically accomplished these
objectives. Construction and QC personnel have been trained with
respect to separation requirements. Effective May 18, 1984, subse-
quent electrical-installations (external to panels) have complied
with Regulatory Guide 1.75. -Also, Stone and Webster and Duquesne
Light Quality Control inspectors have completed an inspection pro-
gram which identified areas requiring rework. The rework is~ virtu-
ally completed. -Further, the licensee has implemented a test pro-
gram to support the cable separation program, regarding the. kinds
and amounts of cable wrapping and cable tray covers necessary for
compliance with the regulatory guide. Except for actual installa-
tion of cable wraps and tray covers, resolution of this item is
complete. This area has clearly shown positive involvement by the
licensee and Stone and Webster's management since the last SALP.
report, and as a result, corrective actions have been responsive
to past concerns.
Other areas discussed in the last SALP report have also received
increased management attention and are showing marked improvement.
The Integrated Construction Support Group (discussed in Functional
Areas 2 ard 9) established by Stone and Webster. Engineering also
plays an important role in resolving issues and questions in the:
field involving electrical issues. This concept of placing engi-
neers in the butidings where the work is being accomplished provides
an excellent contact to field personnel for clarifying and/or re-
solving issues.
The "Constructability Review Team" (also discussed in Functional
Areas 2 and 9) reviewed conduit support drawings and revised draw-
ings where necessary to provide concise and clear information to
the field. Again, this has helped eliminate confusion regarding
drawing requirements which existed during the last SALP period.

'
Generally, the electrical contractor (Sargent Electric) has demon-
strated a sound quality oriented approach to safety issues. With
, some exceptions, no major problems have occurred in the construction
'
and installation of cables and cable trays in accordance with
specifications and procedures. Exceptions are the violation in-
volving minimum bend radius of cable in pull boxes and failure to
cease pulling cable when nonconforming conditions existed on cable
from the pulling operation. Increased management attention is
,
warranted to assure compliance with requirements pertaining to
[ cable damage, bend radius and pull tension.

20
QC personnel and management are well qualified and knowledgeable
of work requirements, specifications and procedures. The training
program for QC inspectors is well conceived, thorough and well ex-
ecuted. Personnel are adequately trained.
In summary, improvement is noted in this area since the last SALP
report. Management, through reorganization and restructuring, has
effectively addressed the cable separation and other problems de-
scribed in that SALP report. This area has received significantly
increased attention by both the licensee and Stone and Webster since
the last SALP report was issued. Most of the identified problems
occurred earlier in the assessment period; resolution of cable
separation concerns is progressing well. Although improvement has
been shown during this assessment period, numerous lingering prob-
lems still exist.
b. Conclusion
Category 2, Consistent. This area continues to warrant priority
licensee / contractor attention.

6. Instrumentation and Control Systems (11%)
a. Analysis
During the last assessment period, control of onsite construction
and inspection activities in this area was considered to be good.
However, several items fabricated offsite were identified as needing
significant inspections and rework. A Category 2 rating was as-
signed.
There was some coverage of this area by the resident inspectors,.
three inspections by region-based specialists, and the CTI included
these systems. Various work in this area continued throughout the
site similar to the last SALP period such as wiring and terminations
in the Control Building and terminations in various control panels.
Also, installation of various flow, pressure and temperature in-
strumentation began in several safety-related systems such as the
Service Water System and the Primary Component Cooling Water System
to support turnover of portions of these systems to the DLC Startup
Group.
Stone and Webster Engineering and DLC Site Quality Control devised
a program to inspect and correct various workmanship problems in
the internal wiring of numerous panels discussed in the last SALP
report. During this assessment period, the licensee completed a
100% reinspection effort of these panels and has corrected many of
the workmanship problems. Also, vendor surveillance inspection
plans were upgraded for any future inspections of wiring at vendor
facilities prior to panel shipment. These action demonstrate the
licensee's continuing commitment to quality.
Four violations were identified late in this assessment period with
three of these violations concerning the installation of instruments
and instrument tubing. The fourth violation concerned the failure
to implement the QualI y Assurance Program when inspecting panel
internal wiring against Regulatory Guide 1.75 separation require-
ments.
The three violations involving the installation of instruments and
instrument tubing were the result of inadequate engineering design
review and ambiguity in the specification and are indicative of a
problem in this area. Specifically, onsite engineering failed to
translate sufficient information from composite drawings to single
line construction drawings used by craft and QC personnel. The in-
sufficient information in tFese drawings regarding installation and
construction criteria such as instrument type, tubing size, loca-
tion, separation, slope and routing led to problems involving in-
adequate separation of redundant tubing, mounting of redundant in-
strument tubing on the same support and failures to mount instrument
vents and drains to direct the discharge away from personnel and

electrical _ equipment. The licensee and Stone and Webster took rapid
corrective action by issuing a stop work order on the installation
of instrument tubing pending an engineering review and resolution
of the-discrepancies. The licensee has proposed tighter engineering
controls, but still does not require Quality Control personnel to
verify separation criteria for instrument tubing.
The violation concerning the lack of QC inspection of panel internal
wiring separation also occurred at the end of this assessment period.
The licensee and Stone and Webster developed a procedure to inspect
the internal wiring in all safety-related panels for compliance with
Regulatory Guide 1.75 and to define the rework necessary for com-
pliance. .While this process appeared to provide a method to upgrade
these panels, these inspection activities did not follow the DLC
Quality Assurance Program in that personnel performing inspections
were not part of the QA function, were not certified to perform in-
spections, and were not independently separated from the organiza-
tion directly responsible for performing the specific activity (Stone
and Webster Engineering in this case). The licensee / contractor needs
to provide additional attention to problem resolution to assure that
actions to resolve deficiencies do not circumvent the existing QA/QC
programs.
In summary, several violations were identified in this functional
area in the last two months of the assessment period. However, other
installation and QC inspection activities have been satisfactory.
Separation requirements for panels (internal wiring) and instrument
tubing are still being addressed; instrumentation separation clearly
received lower priority than cable separation (see Section 4). Clear
definition of engineering criteria and Qualit> Control functions
and responsibilities need to be addressed for instrumentation and
control systems. Further, inspections conducted on safety-related
equipment must be in accordance with the approved DLC Quality As-
surance Program. Additional management involvement is needed in
this area to maintain high quality standards and timely resolution
of separation problems,
b. Conclusion
Category 2, declining.
c. Board Recommendation
Licensee
Resolve internal panel wiring discrepancies in a timely manner.
Assure that separation inspections are in accordance with the DLC
Quality Assurance Plan and verify compliance with requirements.

-7. Licensing Activities
a. Analysis'
This area was categorized as satisfactory (Category 2) during the
previous SALP. Evaluation and monitoring of licensing activities
included routine contact between the NRC and DLC as well as con-
ference calls, site visits, meetings and audits as required. The
major licensing activities during this assessment period involved
the continuation of the NRC stcff review of the FSAR and ER, issu-
ance of the Draft Environmental Statement and Draft Safety Evalu-
ation Report, and preparation for Safety Evaluation Report (SER).
Based on a composite of a number of functional areas, the applicant
continues to demonstrate evidence of prior planning and assignment
of priorities. He has well stated, controlled and maintained ex-
plicit procedures for control of activities. This has been shown
by the applicant's approach to resolving approximately 350 open
items identified in the staff's draft safety evaluatior. report to
support preparation of the final SER. The applicant established
a program to identify and track the status of each item and main-
tained internal schedules for resolving each open item. Generally,
DLC management assigned the necessary technical people to develop
complete, high quality responses,. Further, he has been using the
NRC backfitting procedures provided (e.g., NRC Manual Chapter 0514)
in an attempt to assure that only cost effective safety measures
are implemented.
In a majority of cases the applicant nrovided timely responses to
open issues. The applicant was resptnsive to a majority of the
staff concerns, took the initiative to resolve issues by requesting
conference calls, and meetings, and promptly followed up with sub-
mittals of responses. Responses were generally technically sound,
concise, and addressed the staff's concerns in a professional man-
ner. Some exceptions occurred during the power systems, mechanical
engineering, radiological assessment, meteorology and effluent
treatment, auxiliary systems, and instrument and control systems
portions of the safety review. In these cases, several discussions
and meetings with the applicant were necessary in order to obtain
clarification and reach resolution. Although corporate management
reviews and signs all submittals to NRR, it is felt that increased
direct management involvement might have expedited the resolution
in these cases. Early on, while DLC management urged the NRC staff
to meet their scheduled milestones, they did not provide timely in-
puts of sufficient quality for NRC to meet those milestones. How-
ever, more recently this situation has improved.
DLC generally demonstrated a clear understanding of issues during
meetings and discussions with the NRC staff and in its submittals
to the staff. Its approaches to resolution of technical issues are
r
'
.
o .
24
viable and generally sound and thorough. The applicant was willing
to perform additional studies as necessary to resolve technical
issues. He performed detailed analytical technical work in a timely
manner to support the SER schedule. Generally, when the staff and
the applicant held differing technical positions, the applicant
provided a sound basis for his position. Some exceptions occurred
concerning the auxiliary systems, instrumentation and control sys-
tems, and power systems portions of the safety review. In these
-
cases, tne applicant did not always demonstrate a clear understand-
ing of the issues. Viable approaches to resolution were generally
proposed, however, in some cases it required much more interaction
than normally required.
Positions within the applicant's organization are identified and
authorities and responsibilities are well defined. Generally, suf-
ficient technical staff have participated in review meetings to
effect timely resolution of open items. DLC licensing staff have
been very, effective. However, it is felt that management involve-
ment in resolution of significant issues failed to prevent the need
for additional staff effort to obtain resolution and prevent schedule
-
delays.
Overall, our. conclusion is that, although the reported individual
ratings for the evaluation criteria were variable, the licensee's
performance in this area has been adequate and reasonably effective
in addressing nuclear safety considerations. The increased manage-
ment participation towards the end of the SALP period has contri-
buted to improved understanding and resolution of issues.

8. Storage of Safety Related Components (9%)
a. Analysis
This area is listed as a separate functional area because it was
assessed as a weak functional area in two of the last three SALP
reports. In addition to the resident inspector's daily site tours
and specific inspections, there were three inspections by region-
based specialists.
Storage conditions were observed throughout the site both for
equipment already installed and for equipment still in storage in
the warehouses. Four violations were issued during this assessment
period concerning storage of a variety of plant equipment - instru-
mentation, personnel airlock, piping and motor operators. Addi-
tional NRC concerns occurred involving storage of an assortment of
equipment - coiled cable, sealing electrical terminals, fan motors,
fuel pool heat exchangers, batteries, instrument valve manifolds,
and reactor vessel upper internals. Inspections found moisture
present on the inside surfaces of the fuel pool heat exchangers
(records indicated components were in dry lay-up). In addition,
records indicated water was found two years earlier in the same heat
exchanger and no corrective actions were taken.
With one exception, all of these findings pertained to in place
storage of components. These problems and other NRC findings indi-
cated that during the first part of this assessment period, the
Itcensee's storage program significantly deteriorated from the
category 1 condition which was present at the end of the last SALP
period.
In December, 1984, based on NRC findings, the licensee recognized
that strong corrective actions were necessary to upgrade the storage
program with particular emphasis placed on components requiring in-
place storage and maintenance. A Composite Review Work Group (CRWG)
was formed with construction, engineering and startup personnel from
Stene & Webster, Duquesne Light Ccmpany, Schneider Power Corporation
(SPC) and Sargent Electric Company (SECO). The CRWG conducted a
building-by-building review of the in place storage conditions of
safety-related components beginning in January, 1985, with the
Reactor Building and ending in March, 1985, with the Primary Intake
Structure. Subsequent to these building reviews, SPC and SECO
building and area foremen are being held responsible to maintain
equipment in a properly stored condition until it is accepted for
test. Also, a Management Oversight Committee (MOC) was formed to
review the reports published by the CRWG and by the Management Com-
i mittee for Storage Review which conducts regularly scheduled site
tours with emphasis on in place storage. The MOC, which began
'
functioning in February,1985, is charged with assessing the overall
storage program effectiveness as project conditions change.

!
(CTI) performed in March,1985, when no NRC findings occurred in -
this area. At that time, in place storage of components was gener-
ally good; the team was favorably impressed by in plant conditions.
In summary, the ifcensee's corrective actions have reversed the
deteriorating trend previously observed earlier in theLassessment
. period. However, the long term effectiveness of controls in this
area will be determined by the attention devoted by the contractors
. to in place storage in-their respective work areas. Due to extended
L construction schedules, storage controls of critical components must
receive increased management attention and corrective actions must
, be taken when adverse conditions are found. Licensee management
r must review the storage program efforts on an ongoing basis to en-
sure that the in place storage of components continues to improve
and the recent positive trend in this' area does not become just a
momentary one.

9. Engineering / Construction Interface (6%)
a. Analysis
In the prior assessment period, a Category 3 rating was assigned
to this functional area, primarily due to numerous deficiencies
noted in the contents of design related documents issued by vendors
and contractors. Engineering documents frequently failed to contain
sufficient information and/or information that was clear enough for
field use by Construction and QC personnel. There was inadequate
interface between engineering and construction to resolve the field
problems that resulted from such engineering document deficiencies.
Inspections by the resident inspector included the " Engineering
Confirmation Program", the "Constructability Review Team" and the
Integrated Construction Support Group (ICSG). One inspection was
conducted by a region-based specialist inspector concerning the
" Engineering Confirmation Program" where the validity of an elec-
trical calculation affecting the sizing of 5 KV power cables was
in question. Region-based inspectors reviewed the engineering / con-
struction interface as part of the Construction Team Inspection
(CTI) performed in March, 1985.
Both the licensee and the AE have taken numerous steps during this
assessment period to correct weaknesses in this area and to
strengthen the engineering / construction interface. Some of these
actions concerning the " Engineering Confirmation Progran" had been
underway since October, 1983, as noted in the last SALP report.
The numerous steps taken to improve performance have required addi-
tional experienced manpower. Stone and Webster, in particular, has
substantially upgraded their Site Engineering Group (SEG) with the
addition of senior technical personnel. Several individuals were
added recently, but the major personnel changes occurred between
April and September,1984, when twenty-four additional engineers
were added to the SEG. This group included three new Assistant
Superintendents of Engineering, each of whom brought at least 10
years of engineering and construction experience to his position.
Also included in this staff increase were two principal engineers
in the pipe support area and a senior design supervisor in the
electrical design area. Further, Stone and Webster management ap-
pointed a SEG Site Sponsor who reports to the Stone and Webster
Engineering Manager at Boston, and provides upper Stone and Webster
management attention and support for SEG efforts.
The Duquesne Light Company (DLC) manpower commitment has also been
substantial. An example of such commitment is illustrated by the
expenditure of approximately 11,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> by forty-eight OLC engi-
neers in completing the design bases endorsement effort of the
" Engineering Confirmation Program" with the major conclusion drawn
that OLC has no unresolved concerns with the Beaver Valley Power
,
., . ,
28
Station - Unit 2 Plant Design Bases. NRC found this effort to be
thorough. DLC did identify some specific design discrepancies, but
these are being resolved with Stone and Webster through an effective
follow-on program.
Project utilization of this additional manpower has achieved posi-
tive results in strengthening the engineering / construction inter-
face. This was evidenced in the CTI when it was concluded that im-
provements had been made in the engineering / construction interface
for all functional areas
Distribution area where p,except the Electrical
roblems still Power Supply
exist. As discussed and
in more
detail in Functional Areas 2 and 5, the "Constructability Review
Team" and the ICSG have been instrumental in providing improved
communications between engineering and construction. In particular,
the ICGS has significantly enhanced the engineering / construction /QC
interface by improving the availability and timeliness of engineer-
ing involvement in problem resolution. Mechanical and Electrical
Constructability Review Teams (CRTs) were established in June and
July, 1984, respectively. These CRTs were effective in addressing
past concerns in this area involving cluttered and overly complex
drawings as well as ambiguous, confusing and sometimes conflicting
installation drawings and specifications which often led to inter-
pretations by crafts and QC personnel inconsistent with the de-
signer's intent. These CRTs reviewed all new or revised drawings
before issuance. Dramatic improvements were achieved (from initial
drawing revision rates to resolve CRT concerns of 50-75% to a 3-5%
revision rate by the end of the assessment period). Following the
successes achieved in improving drawing quality, CRT efforts were
also focused on "insta11 ability" reviews (assuring that installa-
tions could be made without problems regarding access, interfer-
ences,etc.). These initiatives (ICSG and CRTs) have been particu-
larly responsive to past NRC concerns in this area.
In summary, substantial improvements in the engineering / construction
interface have been made in all functional areas. In the electrical
and instrumentation Functional Areas, some lingering interface
problems still exist as noted therein. A substantial addition of
experienced, technical personnel by both Duquesne Light Company and,
in particular, Stone and Webster occurred during this assessment
period. Continued high level of management involvement is needed
to solve the weaknesses in the electrical / instrumentation areas
similar to the success achieved in the mechanical area. Also, man-
agement must continue to be sensitive to the engineering /construc-
tion interface in all functional areas to ensure that the recent
improvements remain until the project is completed.

10. Preoperational/Startup Testing (5%)
a. Analysis
This is the first SALP report to separately address this Functional
Area. Two inspections were made in this area by region-based
specialists and there was some additional coverage by the resident
inspectors.
During the assessment period, management changes were made in the
startup area to reorganize all startup activities into a single
group. This reorganization included the addition of personnel from
Shippingport Atomic Power Station and Beaver Vall.ey, Unit 1. These
changes have not been incorporated in the Nuclear Construction
Division Procedures Manual (see Functional Area 11).
Earlier in this period, NRC found that the licensee had not formally
issued a Startup Manual, even though some work was being accomplished
to individual test procedures. By the end of this assessment period,
the Startup Manual had been issued. Another concern identified by
NRC regarded the need for the licensee to provide a procedure which
established the criteria for turning a system over to the licensee.
System turnovers without established criteria limiting the types
of nonconforming conditions that can be accepted have resulted in
high numbers of or.en items. Some of these items require a substan-
tial amount of construction before they are complete. This is con-
sidered to represent a weakness in the program for system turnover
where pressure to show progress is a contributing factor. However,
the CTI did observe that, for the system sampled (primary component
cooling water), all significant discrepancies noted in an extensive
system walkdown were already being tracked in various site tracking
systems.
During the assessment period, the licensee accepted portions of 18
safety-related systems (38 subsystems) from construction; the major
1tems being primary component cooling, service water, main trans-
former and associated protection equipment, 480 volt buses, unin-
terrupted power supply, storage batteries and electrical panels.
One violation was issued during this period; failure to certify
personnel performing walkdown inspections in preparation for system
turnovers. The licensee promptly corrected this item and it has
been accepted by the NRC.
In summary, during this period only the programmatic a'id staffing
aspects of this functional area were evaluated. It is premature
to fully assess the overall quality and effectiveness of the program
implementation at this time. Preliminary reviews have, however,
found weaknesses in the program related to personnel qualification
and establishment of system turnover criteria, which warrant man-
agement attention.

11. Quality Assurance and Administrative Controls
a. Analysis
This is the first SALP report to separately address this functioral
area. Quality assurance activities and their associated admini-
strative controls are also a part of all other functional areas.
Startup operations involve many administrative controls to properly
test, operate and maintain equipment different than construction
activities require. Therefore, administrative controls within the
project take on increasing importance. The licensee's performance
concerning quality was closely monitored by NRC while several re-
organizations occurred within the licensee's Nuclear Construction
Division involving senior management changes during the project
transition.
Inspections performed by the Construction Team Inspection (CTI)
conducted in March, 1985, included specific reviews of the quality
assurance and project management areas. One violation involving
procedural compliance was identified during the CTI; two other vio-
lations involving failures to properly remove hold and reject tags
and properly disposition an N&D concerning cable pull tension were
also identified in othee inspections. All NRC open items are
tracked on a "Next Step List" which is published monthly.
In the past, the licensee has demonstrated an adequate QA program.
The overall QA and QC programs, organizations and responsibilities
continue to be well defined. QA/QC personnel are qualified and
+ rained; staffing has been adequate. QC management is strong and
.
responds to NRC issues as well as plant problems in a technically
sound and timely manner. The licensee is presently implementing
a new program called Quality Improvement Management Program (QIMP)
designed to involve the licensee and constructor / contractor upper
management in improving quality and construction. The program's
objectives are for the regular review of construction's quality
performance, clear assessment of causes for adverse performance
tr. ends, and implementation of appropriate corrective measures for
performance improvement.
Many positive facets of the licensee QA program were evident during
the CTI. However, certain NRC concerns were identified during the
CTI involving numerous organization changes and potential weaknesses
due to several reorganizations in the DLC Nuclear Construction
Division. NRC has expressed a concern that the organizational
changes wherein the QA/QC function reports to the Nuclear Group Vice
President who also functions as the DLC Project Manager may de-
crease the effectiveness of QA/QC.

The procedure violation noted during the CTI affected various docu-
mentation including Stone and Webster Engineering documents, vendor
test reports, receipt inspections, and Westinghouse (NSSS) procedures.
While these items were relatively minor on an individual basis, when
viewed collectively, they show that the project needs to emphasize
the importance of following procedures. This fact was further
illustrated during the CTI when the DLC Nuclear Construction Divi-
sion Procedures Manual was found to be in need of revision in
several areas to reflect the organizational changes made in the DLC
Nuclear Construction Department when the OLC Startup Group was
formed. This was viewed as a project managament weakness since
these DLC Nuclear Construction Department organizational changes
had occurred approximately a year before the CTI. The DLC Nuclear
Construction Division Procedures Manual has not been revised to
reflect these changes.
'
. The licensee's audit program is being effectively implemented and
is generally thorough. Corrective actions for audit findings are
prompt and thorough. Staffing is adequate as evidenced in the ,
timely completion of the audit schedule and followup verification
of audit findings. One of the joint Stone and Webster /DLC audits
of SEG activities was exceptionally detailed and technical in nature
involving several Stone and Webster technical personnel. Such
audits are considered to be an improvement compared to past audits
which were more procedural in nature.
In summary, controls in this area are adequate. Quality Assurance
audits are effective. Quality Control management is effective in
resolving problem areas. Isolated cases of inspector errors have
been corrected and sampling over-inspection of all inspectors' work
should curtail future errors. DLC organizational changes need to
be reflected in the Construction Division Procedures Manual,
b. Conclusion
.
Category 2, Consistent. ,
c. Board Recommendation
Licensee
. Provide project organizational stability. Continue recent initi-
<
atives by completely implementing QIMP. Assure that proper QA in-
dependence from schedule and cost considerations is maintained.

V. SUPPORTING DATA AND SUMMARIES
1. Construction Deficiency Reports (CDRs)
Nine CDRs were submitted by the licensee during the assessment period.
Six of the deficiencies were associated with vendor supplied hardware.
Two corrected CORs, 84-00-07 and 84-00-09, were reviewed by the inspec-
tor during this period, with corrective actions considered acceptable.
Deficiency reports are listed in Table 1.
2. Investigation Activities
The. licensee conducted numerous tests on containment coatings to deter-
mine the validity of an allegation received by the NRC. Based on work
performed by the licensee and inspections performed by the NRC, this
allegation was not substantiated and is closed.
3. Escalated Enforcement Action
None.
4. Management Conferences ,
