For further details with respect to the action see (1) the application for amendment and (2) the Commission's Compliance Evaluation Report. These items are available for public inspection at
~
the Commission's Public Document Room, the Gelman Building,2120 L Street, NW, Washington, DC, and at the Local Public Document Room.
Date of amendment request: September 11,1998 Brief description of amendment: The amendment proposes to delete Technical Safety Requirements (TSRs) 2.3.2.1, "Normetex Pump Discharge Pressure," and 2.3.3.1, "Normetex Pump High Discharge Pressure System." The request also includes changes to related sections of the Safety Analysis Report (SAR) to support deletion of the TSR requirements.
Basis for finding of no significance:
- 1. The proposed amendment will not result in a change in the types or significant increase in the amounts of any effluents that may be released offsite.
, The proposed amendment deletes TSR requirements for the Normetex Pump High Discharge Pressure System. The accident scenario that the system was designed to prevent did not
. change so uranium hexafluoride (UFe) remains the only effluent that may be released, and the l amount remains bounded by the 250 lbs controlled by the Normetex UF, Release Detection System. Therefore, there is no change in the effluents that may be released offsite.
I
- 2. The proposed amendment will not result in a significant increase in individual or cumulative occupational radiation exposure.

4 The proposed amendment does not propose any new or unanalyzed activity for the facility.
l' Therefore, the amendment would not result in a significant increase in individual or cumulative occupational radiation exposure.
- 3. The proposed amendment will not result in a significant construction impact.
l The proposed amendment does not involve any construction, therefore, there will be no
- construction impacts.
- 4. The proposed amendment will not result in a significant increase in the potential for, or radiological or chemical consequences from, previously analyzed accidents.
The proposed amendment deletes TSR requirements for the Normetex Pump High Discharge Pressure System. The accident scenario that the system was designed to prevent did not change, and the potential source term for UF, remains bounded by the 250 lbs controlled by the Normetex UFe Release Detection System. The downgrading of the Normetex Pump High Discharge Pressure System from a quality (Q) safety system to a non-safety safety system is offset by the upgrading of the Normetex Pump discharge block valve interlock to a Q safety system. Both systems were designed to prevent an overpressure of the pump discharge line when the pump discharge block valve closes with the pump still running. Worker protection practices would limit any exposure to the worker from any potential smaller release. Therefore, the proposed _ change will not result in a significant increase in the potential for, or radiological or chemical consequences from, previously analyzed accidents, g

- 5. The proposed amendment will not result in the possibility of a new or different kind of accident.
The proposed amendment does not propose any new or unanalyzed activity for the facility. The l
downgrading of the Normetex Pump High Discharge Pressure System from a quality (Q) safety system to a non-safety safety system is offset by the upgrading of the Normetex Pump discharge block valve interlock to a Q safety system. Both systems were designed to prevent an overpressure of the pump discharge line when the pump discharge block valve closes with the pump still running. Therefore, the arnendment does n)t raise the possibility of a new or different kind of accident.
- 6. The proposed amendment will not resul' in a significant reduction in any margin of safety.
The safety limit proposed for deletion did not change the bounding accident release of 250 lbs. l The downgrading of the Normetex Pump High Discharge Pressure System from a quality (Q) l l
safety system to a non safety safety system is offset by the upgrading of the Normetex Pump discharge block valve interlock to a Q safety system. Both systems were designed to prevent an overpressure of the pump discharge line when the pump discharge block valve closes with the pump still running. With no increase in the potential amount of hazardous material released l and the switching of one Q safety system for another equivalent system, the accident remains l I' unlikely. Therefore, there is no significant reduction in the margin of safety.
- 7. The proposed amendment will not result in an overall decrease in the effectiveness of the plant's safety, safeguards or security programs.

I 6 The proposed amendment would delete a safety limit that was determined not to be safety l significant. The safety margin remains the same. While one safety system has bee -
t4 l
downgraded, an equivalent safety system has been upgraded. Therefore, the deletion of the TSRs and supporting SAR changes do not decrease the effectiveness of the plant's safety l- program. It also does not propose any change to or effect the safeguards and security programs. Therefore, the proposed amendment will not result in an overall decrease in the j effectiveness of the plant's safeguards or security programs.
Effective date: The amendment to Certificate of Compliance GDP-1 becomes effective 5 days after being signed by the Director, Office of Nuclear Material Safety and Safeguards.
Certificate of Compliance No. GDP-1: The amendment will delete the safety limit for the Normetex Pump discharge pressure (TSR 2.3.2.1) and TSR 2.3.3.1,"Normetex Pump High l
