Mr. K. Tosch, Manager IV Bureau of Nuclear Engineering PO Box 415 Trenton, New Jersey 08625

Document Control Desk LR-N04-0359 Attachment I NRC Request for Information:

By letter dated July 29, 2002, PSEG Nuclear (the licensee) submitted a proposed amendment to the Technical Specifications for Salem Nuclear Generating Station, Units I and 2. The proposed amendment would revise the Technical Specifications based on a re-analysis of the design basis Fuel Handling Accident (FHA).

The Nuclear Regulatory Commission (NRC) staff has reviewed the information the licensee provided that supports the proposed Technical Specification changes. In order for the staff to complete its evaluation, the following additional information is requested:

1. The proposed Technical Specification change proposes changing the definition of CORE ALTERATIONS. As a result of the proposed change the applicability section of several technical specifications are proposed to be changed. The applicability is changed from: "During CORE ALTERATIONS or movement of irradiated fuel within the containment" to "During movement of irradiated fuel within the containment."

IN 90-77, "Inadvertent Removal of Fuel Assemblies from the Reactor Core,"

discusses events during removal of upper guide structures and upper internals.

During these events fuel assemblies were inadvertently removed from the reactor creating the high potential for a fuel handling accident.

A review of the Salem licensing bases in UFSAR Section 15.4.6.11 does not specify how the spent fuel assembly is dropped inside of containment.

CORE ALTERATIONS, as presently defined in the Technical Specifications, is the movement or manipulation of any component within the reactor pressure vessel with the vessel head removed and fuel in the vessel. This definition would bound inadvertent movement of a single fuel assembly.

The combination of the proposed change in the definition of CORE ALTERATIONS and applicability statements appear to not bound the known potential for inadvertent movement of fuel assemblies. In light of these considerations please justify why the proposed technical specification change should not include applicability for a fuel handling accident occurring during the movement of other core components.

1 The Salem UFSAR Section 15.4.6.1 states:

"The accident Is defined as dropping of a spent fuel assembly onto the spent fuel pit floor in the fuel handling building or inside containment resulting in the rupture of the cladding of all the fuel rods Inthe assembly despite many administrative controls and physical limitations imposed on fuel handling operations. All refueling operations are conducted in accordance with prescribed procedures under direct surveillance of a supervisor."

PSEG Response:

The dose analysis approved as part of License Amendments 251 & 232 is independent of the manner in which a fuel bundle is dropped. Therefore, the analysis bounds the inadvertent removal of fuel assemblies from the reactor core. In addition, the control room ventilation system required to address this event is required to be operable in all modes (the plant would be in Mode 6 during upper internals removal). Also the proposed BASES state 1

Document Control Desk LR-N04-0359 Attachment I "Either the Containment Purge system or ti eAuxiliary Building Ventilation System with suction from the containment atmosphere, a'ith associated radiation monitoring will be available whenever movement of irradiated {gel is in progress in the containment building and the equipment hatch is open. If for any rmason, this ventilation requirement can not be met, movement of fuel assemblies within the containment building shall be discontinued until the flow path(s) can be reestablished or close the equipment hatch and personnel airlocks."

The present definition of CORE ALTERATION is overly conservative, in that even movement of small components with no potential for causing a Fuel Handling Accident or damage would be considered a CORE ALTERATION. The proposed definition is reasonable. However, to address IN 90-77, procedure SC.MD-FR.FH-0011(Q), 'Reactor Vessel Upper Internals Removal and Inspection", has specific visual checks that are performed to verify that no fuel assemblies are inadvertently lifted during upper internals removal in accordance with procedure. Copies of the relevant portions of this procedure are attached.

The proposed changes are also consistent with Improved TS (NUREG 1431 Rev. 3).

Similar changes have been previously approved for other plants including Turkey Point (Amendments 216/210 TAC NOS. MB2410 & MB2411) and Catawba (Amendments 198/191 TAC NOS. MB3759 & MB3760).

2. Proposed Technical Specification 3.9.4 proposes the following: "The equipment hatch inside door is capable of being closed and held in place by a minimum of four bolts, or an equivalent closure device installed and capable of being closed." Please define what criteria are used to determine whether a device is an equivalent closure device to the equipment hatch. Please define the devices to be used.

PSEG Response:

An equivalent closure device would meet the requirements of Technical Specification 3/4.9.4.a as defined in the Technical Specifications 3/4.9.4 Bases. The equivalent closure device must meet the above technical specification requirements of providing "containment closure" rather than "containment OPERABILITY" as discussed in the above Bases. Closure restrictions must be sufficient to provide an atmospheric ventilation barrier to restrict radioactive material released from a fuel handling accident. Equivalent closure device design criteria are noted in the NRC Safety Evaluation (SE) for Salem Amendments 217 and 199, "The design and fabrication of the equivalent device will be governed by ASME Boiler and Pressure Vessel Code,Section III for Class B Vessels 1968." The SE also notes, "Since pressurization events are unlikely during MODE 6 (refueling) operation, the closure requirement for the equivalent device need only be sufficient to provide an atmospheric ventilation barrier to restrict radioactive material released from a fuel element rupture during refueling operation." The only closure devices currently defined are the Outage Equipment Hatch and the Inner Equipment Hatch.

However, other devices could be used that meet the above criteria.

3. The staff has reviewed Salem's May 1, 2003 response (LR-N03-0136) to the staff's request for additional information related to the proposed license amendment. The response to question 5 does not appear to be responsive to the staff' s question. Please describe the outage activities that could prevent the establishment of fuel handling building closure and the compensatory actions that would need to be taken. It would also be helpful for the staff to understand that in the event of a fuel handling accident that the fuel building would be closed promptly (or within a reasonable time frame) to limit the release of radioactivity.

PSEG Response:

It is PSEG's intention to maintain the Fuel Handling Building (FHB) door closed during fuel movement in the FHB, except for off-normal or plant modification conditions that necessitate the opening of the door during fuel movement. As stated in the PSEG July 29, 2002 License Change Request (LCR S02-010) at page 6 of Attachment 1, the Fuel Handling Building doors shall be maintained closed except for normal entry and exit unless a designated person is available to close the open door(s) should a FHA occur within the Fuel Handling Building. An activity that could prevent the establishment of fuel handling building closure might be installing a through-wall penetration for piping (The Containment Fan Coil Unit Project piping installation described in LCR S03-07 LR-N04-0089, dated April 15, 2004 is an example). In this case, fuel handling could be terminated or compensatory actions established with designated persons available to promptly carry out a pre-planned task.

These compensatory measures may include the use of a material that can provide a temporary atmospheric pressure, ventilation barrier such as providing a temporary ventilation cover for the opening. In the event of a fuel handling accident, the FHB door would be closed promptly based on Administrative Controls described in the proposed Technical Specification 3/4.9, Refueling Operations, BASES.

4. Per page 6 of the July 29, 2002 amendment request, the ability to close the Salem equipment hatch is dependent on AC power. In the case of a loss of AC power coincident with a fuel handling accident, electrical power may not be available for closing the hatch. Please explain what measures are in place to promptly close the equipment hatch without AC power. NUREG-1449 also states that with four bolts installed that the Salem equipment hatch had gaps between the equipment hatch seals. How many bolts will be needed to close the equipment hatch to prevent the release of radioactivity?

2 NUREG-1449, 'Shutdown and Low-Power Operation at Commercial Nuclear Power Plants in the United States," page B-5.

PSEG Response:

The refueling equipment is powered from offsite power, and in the case of a loss of AC power fuel handling would be terminated. The case of a loss of AC power coincident with a FHA, is unlikely since there is no reason that a FHA would cause a loss of AC power and the refueling equipment fails safe on loss of power. In addition, the approved dose analysis does not credit containment closure (See the PSEG July 29, 2002 License Change Request (LCR S02-010) at page 3 of Attachment 1, DOSE CALCULATIONS). Prompt containment 3

Document Control Desk LR-N04-0359 Attachment 1

6. Provide the criterion used to decide if the containment personnel airlock and the containment equipment hatch are capable of being closed within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

PSEG Response:

The Containment Building Closure on Page 5 and 6 of the PSEG July 29, 2002 License Change Request (LCR S02-01 0), describes the methods to assure that the containment closure will be accomplished within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The plant has already demonstrated this 1-hour closure capability for the Outage Equipment Hatch for support of operation at mid-loop (Procedure SC.MD-FR.CAN-0001(Q), "Outage Equipment Hatch Installation, Removal, Seal Replacement and Door Manipulation for Containment Closure"). Administrative Controls discussed in Technical Specifications 3/4.9.4 Bases will be in place and similar demonstrations will be conducted for fuel handing with the Equipment Hatch (or other closure when the Outage Equipment Hatch is not used). The procedure(s) will specify that a containment closure team will be designated and should not perform job functions that may interfere with a team members' ability to immediately respond for containment closure.

Page 5 and 6 of the PSEG July 29, 2002 License Change Request (LCR S02-010),

describes the conditions that must be met prior to fuel movement with the hatch open. If these conditions are not met fuel movement could continue only with the equipment and personnel hatches closed. The above noted section states, "The following requirements shall be maintained to ensure defense-in-depth".

7. What criteria will be used to determine if closure of the containment is necessary in the event of adverse weather? Has the impact of wind on fuel handling been evaluated (for example, reduced pool visibility due to pool surface disruption)? What steps would be taken in the event of severe weather to minimize the impact of flying debris or missile hazards?

2 NUREG-1449, Shutdown and Low-Power Operation at Commercial Nuclear Power Plants in the United States," page B-5.

PSEG Response:

The site procedures for severe weather, NC.OP-DG.ZZ-0001, "Severe Weather Guide" and SC.OP-AB.ZZ-0001, "Adverse Environmental Conditions", will be used for criteria to determine if containment closure is required. These procedures are based on severe weather advisories or bulletins and actual measured site weather conditions.

Discontinuing fuel movement is currently addressed in procedure SC.OP-AB.ZZ-0001 (Steps 3.4 & 3.7, copies of procedure steps attached) if adverse weather conditions occur.

The procedure will be revised to more explicitly address containment closure as part of the implementation of the amendment approving this License Change Request.

Document Control Desk LR-N04-0359 Attachment 1

8. Will your Emergency Plan be updated to include an accident release through the equipment hatch? Will your Emergency Operating Procedures be updated to address the specific details needed to respond to this accident scenario?

PSEG Response:

The Emergency Plan and implementing procedures address fuel handling events regardless of the manner in which they occur. Therefore, no Emergency Plan or implementing procedure changes are needed. However, plant procedures will be revised as needed to address containment closure within one hour in order to respond to any fuel handling event.

9. Will you inform the State Emergency Response personnel about this accident scenario?

PSEG Response:

The State Emergency Planning personnel in New Jersey are aware of this amendment request since they receive copies of the License Change Request and any responses to requests for additional information. In addition this License Change Request has been discussed during interface meetings with the New Jersey Department of Environmental Protection Bureau of Nuclear Engineering. The State Emergency Planning personnel in Delaware will be notified of the amendment when it is approved.

10. The proposed technical specification specifies that a "designated" crew is available to close the Containment Structure Equipment Hatch Shield Doors rather than a "dedicated" crew who would have no other duties. Specify what other duties the designated crew will have and where they will be stationed relative to the air lock doors.

PSEG Response:

The plant has established procedures for a 1-hour closure capability when the Outage Equipment Hatch (OEH) is installed in support of Mid-Loop Operations in procedures S1(S2).OP-AB.CONT-0001, "Containment Closure Abnormal Procedure" and SC.MD-FR.CAN-0001, "Outage Equipment Hatch Installation, Removal, Seal Replacement and Door Manipulation for Containment Closure". The designated OEH Door Closure Team has defined team capabilities, responsibilities, pre-staged equipment, and is limited in their other job functions that may interfere with team members IMMEDIATELY responding for door closure (SC.MD-FR.CAN-0001, Step 5.5.3 CAUTION and Step 5.6 NOTE, copies attached). As part of the implementation of the amendment approving this License Change Request, the Administrative Controls discussed in Technical Specifications 3/4.9.4 Bases will be implemented and similar demonstrations will be conducted to support fuel handling administrative controls with the Equipment Hatch (or other closure device when the Outage Equipment Hatch is not used) open. The duties of the personnel designated to close the hatches will take into consideration the need to promptly (within one hour) close the containment hatch. With the pre-staging of tools and equipment to support hatch closure and in accordance with the administrative controls described in PSEG's submittal, Hatch closure will be achieved within one hour.
