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.

NOTICE OF VIOLATION

Dear Mr. Eliason:

i

On March 17i 1997, the NRC completed an inspection at your Hope Creek reactor facility.

The enclosed report presents the results of that inspection.

During.the 6-week period covered by this inspection, your conduct of activities at the Hope

.

Creek facility was generally characterized by safety-conscious operations, sound

..

maintenance practices, and careful radiological work controls. We were encouraged by

some of the conclusions in the operations and maintenance areas, particularly regarding

improved material conditions; the aggressive posture of your independent oversight groups;

-l

and detailed self-assessment activities, While these latter two issues were considered

I

positively, the findings of these activities also' indicated the need for continued

improvement in maintenance and operations.

We are concerned about two violations of NRC requirements'that were identified in the

first instance,' NRC inspectors identified that the use and control of scaffolding in safety-

1

related areas of the plant was not in accordance with your station administrative

, procedures. This violation is cited in the enclosed Notice of Violation, and the

circumstances surrounding the violation are described in detail in the enclosed report.

Please note that you are required to respond to this letter and should follow the

j

. instructions specified in the enclosed Notice when preparing your response. ~ In the second

instance, a repeat surveillance test failure of a testable check valve in the reactor core

isolation cooling system revealed ineffective corrective action implementation for previous

like failures. This latter violation of 10 CFR 50 Appendix B, Criterion XVI, resulted in LER

50-354/97-03 00 being submitted. Based on a review of the referenced LER, the

'

inspectors noted that your analysis and corrective actions for this event were appropriate.

As such, this violation is being treated as a cited violation not requiring a response. If,

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

instructions.

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

nor are the initiating event mechanisms being changed. . .." While Package No. 3,

j

which installed the cross-tie between the "B" and "D" RHR injection loops, did

l

review the ECCS technical specifications, it still concluded that there was no

l

"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
