PREDECISIONAL ENFORCEMENT CONFERENCE (NRC INSPECTION
4
REPORT 50-354/97-01)
'
Dear Mr. Eliason:
This letter refers to NRC Inspection Report 50-354/97-01 completed on March 17,1997 at
the Hope Creek Generating Station. During the inspection the NRC identified, in section
E1, that a design change package which added crosstie piping in the RHR system was
based on a weak 10 CFR 50.59 evaluation. Based on further NRC review, we concluded
that your evaluation failed to identify an unreviewed safety question prior to implementing
the modification.
This information was provided to you as a clarification of earlier findings during a June 26,
1997 teleconference between Mr. M. Bezilla, PSE&G, and Mr. J. Linville, of NRC Region I.
At that time, you were also informed that the NRC has concluded that the failure to obtain
NRC approval prior to implementation of a design change that involved an unreviewed
safety question constituted an apparent violation of NRC requirements set forth in 10 CFR 50.59. Another apparent violation associated with the safety evaluation for the RHR
crosstie design change was also identified. This apparent violation involved the failure to
'
perform related monthly ECCS flowpath verification surveillance testing in accordance with
TS 4.5.1.a.1.b as described in your LER 97-005. These apparent violations are being
considered for escalated enforcement action in accordance with the " General Statement of
Policy and Procedure for NRC Enforcement Actions" (Enforcement Po! icy), NUREG-1600.
Accordingly, no Notice of Violation is presently being issued for these findings. In
addition, please be advised that the number and characterization of apparent violations
may change as a result of further NRC review.
A predecisional enforcement conference is currently scheduled for 10:00 a.m., August 12,
l
1997, to review the matter. The decision to hold a predecisional enforcement conference
does not mean that the NRC has determined that a violation has occurred or that
enforcement action will be taken. This conference is being held to obtain information to
enable the NRC to make an enforcement decision, such as a common understanding of the
facts, root causes, missed opportunities to identify the apparent violation sooner,
corrective actions, significance of the issues and the need for lasting and effective
corrective action.

in particular, we want to understand the results of your evaluation of the 10 CFR 50.59
and engineering performance issues as described in your LER 97-005 and your assessment
,
of the effectiveness of the increased 10 CFR 50.59 training and qualification requirements
that were implemented, in part, in response to previous violations of 10 CFR 50.59 as
l
outlined in your violation response letter dated November 22,1996. In addition, this is an ,
opportunity for you to identify any errors in our assessment and for you to provide any
information concerning your perspectives on 1) the severity of the violation (s), 2) the
application of the factors that the NRC considers when it determines the amount of a civil
penalty that may be assessed in accordance with Section VI.B.2 of the Enforcement Policy,
and 3) any other application of the Enforcement Policy to this case, including the exercise
of discretion in accordance with Section Vll. This conference will be open to public
observation.
You will be advised by separate correspondence of the results of our deliberations on this
matter. No response regarding these apparent violations is required at this time.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter
and its enclosure will be placed in the NRC Public Document Room.

EXECUTIVE SUMMARY
Hope Creek Generating Station
NRC Inspection Report 50-354/97-01
This integrated inspection included aspects of licensee operations, engineenng,'
j
maintenance, and plant support. The report covers a 6-week period of resident inspecton.
One specialinspection activity, a Maintenance Rule team inspection, occurred during this
period; however, the results of that inspection will be documented in NRC Inspection
Report No. 50-354/97-80.
i
Operations
-
As a result of the lack of explicit procedural guidance, some operators were confused
regarding the main steam line isolation actuation setpoints for the high radiation safety
feature per the requirements of technical specification 3.3.2 during planned hydrogen
water chemistry injection (HWCl) system flow reductions. (Section 01.2)
Operators were found to be effectively controlling standby safety auxiliaries cooling system
(SACS, soop temperature; however, operational guidance was not thorough. Additionally,
the UFSAR did not accurately reflect the current design basis and operating condition
which permits continuous SACS flow to the residual heat removal heat exchangers,
however, the licensee had previously recognized this problem and had initiated appropriate
changes to the UFSAR. (Section 01.3)
Operator response to two plant events was good, in that the necessary immediate actions
were taken; the events were properly classified in accordance with the licensee's Event
Classification Guide (Emergency Plan); and, NRC reporting requirements were met.
(Section 01.4)
The inspectors concluded that operator performance improvements had occurred during
this period. (Section 02.1)
The inspectors concluded that the licensee's QA/NSR report on an event involving an
inadvertent half scram was accurate, comprehensive and complete. This report was
viewed as an indicator of good performance in self-assessment activities. Further, station
personnel performance as described in the report during this event indicated weaknesses in
the use of the corrective actions program, due to personnel not documenting Action
Requests in a timely manner and in proper log keeping by plant operators regarding plant
conditions. These concerns were considered examples of a non-cited violation. (Section
07.1)
Based on a review of selected records and reports, the inspectors concluded that the
licensee's self assessment process and corrective action program were being appropriately
used and provided valuable performance assessment information to station management.
(Section 07.2)

LVlaintenance
The licensee adequatoly planned and controlled the observed maintenance and surveillance
activities. The work was conducted in a professional manner and timely completed to
ensure that equipment restoration to service was within the technical specification
requirements for all observed activities. (Section M1.1)
.
The licensee's analysis and corrective actions for a human error event leading to a primary
containment isolation system actuation were appropriate. (Section M2.1)
The licensee management actions to reduce the backlog of corrective maintenance work
were evident. While too early to conclude that the management of the work process had
been improved significantly, the trend information from the licensee performance indicators
was positive. (Section M2.2)
The licensee plans and corrective actions were found reasonable for the identified concerns
with degraded Agastat GP Series and Struthers-Dunn relays. However, the NRC was
concerned that: (1) the material condition of the plant was adversely affected by these
degraded conditions; (2) the conditions indicated weaknesses in the licensee's planned
maintenance program and industry operating experience program; and, (3) extensive
evaluation and repairs were necessary to resolve these relay problems while the plant was
on line. (Section M2.3)
Hope Creek test procedures for safety-related ventilation trains do not implement technical
specification surveillance requirements consistently. (Section M3.1)
The QA audit of the maintenance program showed that additional improvements were
warranted in the maintenance area. The audit activity was well planned and excellently
performed. The audit findings were well supported by observations and provided
significant information to mai.;gement in order to improve the rnaintenance programs.
(Section M7)
Enaineerin_g
The licensee's implementation of Design Change Package (DCP) No. 4EC-3411 was, in
part, based upon a weak 10 CFR 50.59 evaluation, which indicated a weakness in the
engineering development, review and approval process of 10 CFR 10 CFR 50.59
evaluations to support design changes. The licensee's evaluation failed to identify a
potential unreviewed safety question involving a malfunction of equipment important to
safety (Iow pressure coolant injection system) and need for a technical specification
requirement change in order to implement the modification. Further, since this DCP was
implemented over the course of several years with different parties involved in the 10 CFR 50.59 review and approval, it was further concluded that numerous opportunities were
available for the licensee to identify this problem. (Section E1.1)
While a potential unreviewed safety question was identified, the inspector verified that the
residual heat removal (RHR) system cross-tie isolation valves were properly installed,
providing double isolation capability; and, that the valves were being maintained closed
iii

.
ensuring the independence of the low pressure coolant injection (LPCI) subsystems.
(Section E1.1)
The inspector also concluded that DCP 4EC-3411 documentation was thorough. The
observed portions of the completed field work indicated good installation implementation.
Testing considerations were found appropriate and test completion timely. (Section E1.1)
A repeat failure of the reactor core isolation cooling (RCIC) system turbine exhaust checx
valve inservice test highlighted past deficiencies in PSE&G's design change process to
ensure that modifications implemented to correct failures were designed appropriately.
Also, this repeat failure indicated a weakness in the corrective action program to ensure
that the failure was corrected. H;. wever, the recent effort to identify causal factors
associated with this evert ::.d develop lasting corrective actions was good. (Section E2.1)
Poor implementation of established scaffolding control guidance enabled the installation
and retention of several scaffolds in safety-related areas, including the "A" and "B"
residual heat removal pump rooms and the standby liquid control pump room in the reactor
building of the Hope Creek station without adequately evaluating the impact of these
structures on the design and licensing basis of the facility. This was considered a violation
of licensee procedure controls. (Section E2.2)
Plant Suonort
PSE&G appropriately tested the EDG room ventilation fire dampers and has established
appropriate controls to ensure this activity is completed on a periodic basis and in
accordance with the programmatic description in the UFSAR. (Section F2.1)

The inspectors reviewed selected portions of the completed design change
packages that installed the cross-tie capability to the RHR system during Refueling
Outages 5 and 6 to determine if adequate controls were implemented to maintain
the original design basis of the affected sy!tems and to ascertain if the plant
modification packages contained clear and ccurate installation and test
instructions.
I
\\
The inspectors reviewed selected portions c(f Design Change Package (DCP) No.
4EC-3411 to ascertain that the design, instaMation and testing of the RHR cross-tie
subsystems were accomplished safely and introduced no unreviewed safety
questions.
b.
Observations and Findinas
DCP 4EC-3411 involved the modification of the RHR system to install a discharge
cross-tie between the "C" header and the "A" RHR heat exchanger, and also
between the "D" header and the "B" RHR heat exchanger. This modification
involved: the installation of two 18-inch cross-tie headers and associated vents and
drains; installation of structural supports for the new cross-tie piping and
modification of original piping and structural supports in the RHR rooms to eliminate
interference with the new equipment; core bore new wall penetrations to facilitate
the installation of the new piping; changes to the pump start control interlocks to
add a new key-lock bypass switch for the "C" and "D" RHR pumps to permit pump
start with their respective torus suction valves closed; and, installation of four (two
per cross-tie) new 18-inch, 300 psi, Anchor Darling cross-tie gate isolation valves,
two of which were to have Limitorque motor-operators.
The installation of this modification was completed over several years commencing
with work on the "A" and "C" cross-tie during Refueling Outage 5 in March 1994,
an6 completing with "B" and "D" cross-tie during Refueling Outage 6 in March
1996.
In the area of design control, the inspector observed that the rnodification packages
provided adequate post-modification testing instructions. The testing requirements
were reviewed and found consistent with the appropriate requirements. Also noted
was that some testing had not been completed for the motor operators on the new
cross-tie isolation valves. However, that part of the design change, providing
l
electrical power to the motor operators, had not yet been field completed.
Therefore, deferring the motor operator testing was not a problem.

The inspector noted, that considering the complexity of the DCP, very few field
changes were required for this modification, indicating that the change package was
l
of high quality. A sample of SORC meeting minutes were reviewed to ensure that
l
the DCP and the associated 10 CFR 50.59 safety evaluation were reviewed and
approved by SORC prior to implementation. During a review of one of the
associated SORC meeting minutes, dated September 27,1995, the inspector noted
that SORC had reoucated the PRA group perform an analysis of the design change
i
due to the creation of new high stress locations for the associated piping. PRA
provided an estirnate that the introduction of the new high stress locations for the
-
moderate energy _ RHR piping resulted in at worst, an insignificant increase in the
average Core Damage Frequency. SORC then approved the 10 CFR 50.59
evaluation based on this clarification.
Tne inspector noted that the design change review and approval and the necessary
j
procurement of components was completed in a timely manner to support the
modification implementation. Further, the modification package provided clear
installation instructions. Also, the inspector reviewed the UFSAR changes that
were made to incorporate the new design, and found that the licensee had properly
revised the UFSAR. The inspector walked down accessible portions of this
modification and found that the as-built configuration agreed with the design
drawings and that the new flow path valves were allin their required positions
(closed) per the licensee's system alignment procedures for the current operating
condition (power operations).
The inspector reviewed the associated 10 CFR 50.59 evaluations for the
modification and found that they were written clearly and except as described
below, provided sufficient bases for the acceptance of the proposed modification.
One concern that the inspector noted was that the safety evaluation did not
consider an erroneous valve lineup that would lead to two of the RHR subsystems
(Low Pressure Coolant injection or LPCI subsystems) being cross-tied 'during power
,
'
operations as a credible failure. It appeared to the inspector that the licensee
accepted this design because the modification was single-failure proof (included
dual isolation valves) and had appropriate administrative controls to ensure proper
valve lineup, that the original design and licensing basis (as stated in Section 6.3 of
the UFSAR) of having four separate LPCI subsystems was maintained.
l
The inspector considered that the UFSAR description of LPCI stated:
"LPCI is an operating mode of the RHR system. Four pumps deliver water
from the suppression chamber to four separate reactor vessel nozzles and
inject directly into the core shroud region. . . ."
Also, Section 5.4.7.1 of the UFSAR describes the design bases of the RHR System
as:
"The RHR System consists of four independent loops A, B, C and D as
shown in Figure 5.4-13. Each loop contains a motor driven pump, piping,
!
valves, instrumentation, and controls. Each loop takes suction from the
!
!
_
.
.
,.
.
,
16
suppression pool and is capable of discharging water to the reactor vessel
via separate LPCl nozzles, or back to the suppression pool via a full flow test
line."
Further clarification of this original licensing basis is found in Section 6.3.1 of
NUREG 1048, Safety Evaluation Report related to the operation of the Hope Creek
<
Generating Station, which states:
"The LPCI system is provided to replace reactor vessel water inventory after
large pipe breaks. The system is an operating mode of the residual heat
removal system. It consists of four independent loops. Each loop has a
motor-driven pump that takes suction from the suppression pool and supplies
water to the reactor vessel at a flow rate of about 10,000 gpm. Four
separate nozzles discharge directly inside the core shroud. . . ."
In the onginal design of the RHR system, the LPCI injection flow path was
)
physically separate with no interconnection of piping from the RHR pumps to the
reactor vessel. The suction of the RHR pumps utilized separate suction strainers
from the suppression pool with individual suction isolation valves; however, a cross-
.
tie with dual manual isolation valves connected the suction supply lines. After
I
reviewing the pertinent design basis documentation, the inspector concluded that
)
the modification installing the cross-tie between the discharge or injection paths,
still adequately assured electrical separation of the independent LPCI subsystems;
however, the mechanical separation criteria were changed.
I
The licensee's 10 CFR 50.59 evaluations recognized this change and did properly
i
evaluate the potential for internal flooding events, etc., as a result of pipe breaks.
However, the 10 CFR 50.59 evaluations did not rigorously review the potential loss
i
of more than one LPCs flow path resulting from an erroneous valve alignment that
I
could change the expected availability of the LPCI subsystems to respond to a
j
postulated LOCA event. Design Change Package Nos.1 and 2 of the DCP, which
'
installed the cross-tie between the "A" and "C" RHR injection loops, did not
consider a review of the ECCS TS when determining the acceptability of the design
change. Further, the 10 CFR 50.59 evaluation concluded that there was no
"Unreviewed Safety Question" due to the fact that " . . .neither the performance of
1
the systems required to mitigate the consequences of an accident is being changed,
!
nor are the initiating event mechanisms being changed. . .." While Package No. 3,
j

"Unreviewed Safety Question" on the same basis as stated in DCP Package Nos.1
and 2.
The inspector questioned with this conclusion because the DCP changed the design
of a system that is used to mitigate the consequences of an accident, namely, the
LPCI mode of the RHR system. Because the original design of the LPCI system had
no chance of two injection paths being cross-tied during an accident mitigation, the
probability of such an event after implementing the DCP may be greater. The
modification created a potential accident without an LPCI independent injection flow

path, if the respective isolation valves were erroneously left open during power
operation. Further, the licensee's evaluations did not address the consequences of
such a malfunction of the LPCI system as could occur with the cross-tie valves
open during power operations.
.
After the inspector raised the concern about the inappropriate consideration of the
affect on the LPCI system, the licensee identified that d.+ cross-tie valves should
probably have been considered part of the LPCI flow path for surveillance testing
per TS 4.5.1 (b). This surveillance demonstrates that the ECCS flow path valves
are in their correct position on a monthly basis, if not locked, sealed, or otherwise
secured in position. The applicable surveillance test procedures had not been
changed upon implementation of the DCP. However, the inspectors were informed
that the valves were being visually observed on a monthly basis in order to satisfy
extended containment boundary procedure requirements that were changed to
incorporate the DCP implementation.
The inspector concluded that the four,18 inch, cross-tie isolation valves should
have been considered part of the LPCI flow path. Failure to ensure that the ECCS
surveillance test procedure accurately reflected the actual design of the system was
viewed as a further indication of a weak engineering evaluation to support the DCP.
However, baseu on a review of the current standard technical specifications, as well
as the technical specifications for the Limerick station that employs a similar design,
the inspector noted that RHR cross-tie isolation valves received specific surveillance
requirements beyond that of TS 4.5.1 (b). The standard technical specifications
required a monthly surveillance requirement specifically for the RHR cross tie
isolation valves to ensure that they were closed and their motor operators de-
energized. The standard technical specification bases described that this
requirement ensured that the LPCI loops remained independent, so that a
malfunction in one subsystem would not affect any other subsystem. Therefore,
the inspector was further concerned that the engineering evaluation for this
modification should have identified the unreviewed safety question described above,
and should have resulted in a technical specification change incorporating the
requirements of the standard technical specifications, or similar, for the LPCI cross-
tie isolation valves. This itern is unresolved pending further NRC review. (UNR 50-
354/97-01 04)
c.
Conclusion
The inspector concluded that the licensee's implementation of Design Change
Package No. 4EC-3411 was, in part, based upon a weak 10 CFR 50.59 evaluation,
which indicated a weakness in the erigineering development, review and approval
l
process of 10 CFR 50.59 evaluations to support design changes. The licensee's
evaluation failed to identify a potential unreviewed safety question and the need for
a technical specification change in order to implement the modification. Further,
since this DCP was implemented over the course of several years with different
parties involved in the 10 CFR 50.59 review and approval, it was further concluded
that numerous opportunities were available for the licensee to identify this problem.
,
While there may be an unreviewed safety question, the inspector verified that the

cross-tie isolation valves were properly installed, providing double isolation
capability; and, that the valves were being maintained closed ensuring the
. independence of the LPCI subsystems.
The inspector also concluded that the DCP documentation was thorough. The
observed portions of the completed field work indicated good installation
implementation. Testing considerations were found appropriate and test completion
was timely.

Testable Check Valve Failures
a.
Insoection Scope (37551. 62707)
The inspectors reviewed PSE&G's response to a failed inservice test of the RCIC
system turbine exhaust check valve. The assessment included an evaluation of the
licensee's reporting of this event, short term corrective actions, and effectiveness of
corrective action program implementation,
b.
Observations and Findinas
On February 4,1997, operators declared the RCIC system inoperable following an
inservice test failure of the associated systern turbine exhaust check valve, a
testable 10" Anchor Darling swing check. During the test of this valve, the
operators were unable to engage the valve disc with a cam that is attached to the
test handle. A subsequent internalinspection by maintenance technicians revealed
that the cam, which is positioned on the valve disc hinge shaft with a set screw,
had slipped from its required position, rendering the valve untestable. Technicians
adjusted the cam position as required and fixed it in place with the set screw. The
valve was reassembled and the RCIC system was declared operable on February 5.
In part because operators reported this event per 10 CFR 50.72 as an unplanned
inoperability of a single train safety system, Hope Creek management assigned a
significance level 1 condition report to the engineering department to perform a
detailed root cause evaluation of the event. The inspectors interviewed the
responsible engineering personnel as well as the documented root cause
determinations, along with recommended corrective actions. As a result of the
investigation, PSE&G determined that this same check valve had failed two times
previously, in 1992 and 1995, for similar reasons. Additionally, the analogous high
pressure coolant injection (HPCI) check valve had failed under these circumstances
in 1989.
l
The licensee's investigation concluded that a 1989 DCP which modified a
l
population of nearly 45 swing check valves with the test handle mechanism (to
!
facilitate periodic inservice tests), f ailed to provide adequate technical guidance to
ensure that the set screw which secures the cam to the disc hinge shaft would

remain engaged. Specifically, though the modification concept included a provision
