Date of amendment request: November 5,1998 Brief description of amendment: The amendment proposes to change the completion dates for Compliance Plan issues 46 and 50. The completion dates are being changed from f .
December 15,1998, to January 18,2000. These issues require plant modifications to ensure that the criticality accident alarm system (CAAS) alarm horns are capable of being heard throughout the affected areas of the process buildings and to provide CAAS alarm horns for
' those unalarmed facilities within the evacuation area of other buildings. USEC will provide 4
alternative means of personnel notification in the event of a CAAS alarm. The amendment also
. proposes criteria for determining audibility of the CAAS alarm horns.
Basis for finding of no significance:

. 4 l
- 1. The proposed amendment will not result in a change in the types or significant increase in I
the amounts of any effluents that may be released offsite. l 1
The proposed changes ta the Compliance Plan completion dates and the addition of criteria for I determining alarm horn audibility will have no effect on the generation or disposition of i effluents. Therefore, the proposed changes will not result in a change to the types or amount of I l
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.
The CAAS does not prevent criticality, therefore, the possibility of a criticality occurring is not i
increased. However, in the unlikely event a criticality did occur, the personnel notification might n'ot be as prompt as relying on the CAAS horns. Therefore, the potential radiation exposure for j an individual could be higher because the individual remained in the area for a longer period of !
time. This slight chance for increased exposure is not considered to be significant. The l proposed changes will not significantly increase any exposure to radiation due to normal operations. Therefore, the changes will not result in a significant increase in individual or i
cumulative occupational radiation exposure.
- 3. The proposed amendment will not result in a significant construction impact.
The proposed changes will not result in any building 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 CAAS system is not involved in any precursor to an evaluated accident. Extension of the completion data for the modifications to improve CAAS audibility has no effect on the probability of occurrence of a criticality accident. The consequences of a potential criticality accident will not be significantly increased since the ability of the CAAS to detect a criticality is unchanged and the compensatory measures currently in place will remain in place until the modifications are completed. it is possible that personnel exposur e could be slightly increased due to possible short delays in personnel notification. The addition of acceptance criteria for subjectively measuring audibility will not alter either the probability or the consequences.
Therefore, these changes will not significantly increase the probability of occurrence or consequence of any postulated accident currently identified in the safety analysis report.
- 5. The proposed amendment will not result in the possibility of a new or different kind of accident.
The CAAS is used to mitigate the consequences of a criticality accident. The proposed changes do not introduce any new or different accidents than those previously analyzed.
Therefore, the proposed changes will not create the possibility of a new or different type of equipment malfunction or a new or different type of accident.

- 6. The proposed amendment will not result in a significant reduction in any margin of safety.
The proposed changes to the completion dates for the CAAS modifications extend the period for having areas of the plant not covered by the an audible alarm horn, however, the compensatory measures provided in Compliance Plan issues 46 and 50 will remain in place.
i These include use of building howlers for the process buildings and the use of radios in unalarmed buildings. These measures will provide adequate notification in the event of a l criticality accident. The proposed acceptance criteria for determining audibility provide a subjective maans for ensuring audibility. Therefore, the changes do not result in a significant i decrease in the margins of safety.
l
- 7. T he proposed amendment will not result in an overall decrease in the effectiveness of the l
plant's safety, safeguards or security programs.
The proposed changes do not change the safeguards or security programs. The CAAS audibility acceptance criteria provide a subjective means of determining audibility and may improve the effectiveness of the safety program. The continued use of alternative methods of notification for the CAAS alarms (building howlers and radios) due to the extension of the completion dates for Compliance Plan issues 46 and 50 will ensure that personnel are promptly notified of CAAS alarms. Therefore, the overall effectiveness of the safety, safeguards, and security programs is not decreased.
- s. 7 Effective date: The amendment to Certificate of Compliance GDP-1 becomes effective imrfiediately after being signed by the Director, Office of Nuclear Material Safety and Safeguards.
Certificate of Compliance No. GDP-1: Amendment will revise Compliance Plan Issues 46 and 50 to reflect the new completion dates of January 18,2000. The amendment will also add acceptance criteria for determining CAAS alarm horn audibility.
