Enforcement Conference Details Mr. Wenslawski summarized the four apparent violations, described in Inspection Report 70-1257/93-05, that involved the failure to: (1) i follow procedures for modification of systems that involve fissile material, (2) follow operating procedures (taping of a safety interlock), (3) include safety modifications in the applicable criticality safety analyses, and (4) perform an adequate evaluation of the potential for moderator intrusion.
.j
}
Mr. Femreite stated that SPC had reviewed the inspection report and that Mr. Mass would present SPC's position relative to the NRC's findings as described in the report.
Mr. Valentine summarized SPC's immediate response and corrective actions related to the February 7th event and their evaluation regarding the potential for the intrusion of moderating liquids into the conversion line 2 powder preparation systems (Enclosure 2). Mr. Maas presented the licensee's response to the apparent violations (Enclosure 2) and stated that SPC did not disagree with the violations involving the failure to (1) follow procedures for modification of systems that involve fissile material, and (2) follow operating procedures (taping of a safety interlock). However, SPC did not concur with the apparent violations involving the failure to (1) incorporate the limit switches into the CSAs, and (2) perform an adequate evaluation of the potential for moderator intrusion.
During the course of the conference, Mr. Vaughan presented a summary of SPC's CSA Update Program (Enclosure 2). Mr. Femreite presented a summary of improvements SPC has made during the past year, mitigating factors for enforcement and conclusions as to why escalated enforcement action should not be taken in this case (Enclosure 2). Regarding the taping of the limit switched, Mr. Femreite stated that SPC's management does not condone such actions regardless of the safety significance involved. Mr. Faulkenberry acknowledged the licensee's program improvements and stated that the NRC would review the issues discussed to determine the appropriate enforcement action.

NRC INSPECTION REPORT NO. 70-1257/93-05 STATEMENT OF APPARENT VIOLATION 2 On February 7,1993, following the inadvertent discharge of about 124 kg of UO powder from the 2
Line 3 blender's feed hopper to its respective lexan enclosure, the licensee and an NRC inspector observed that the limit switches (interlocks) on the discharge tube on the feed hopper of the Line 2 and Line 3 blenders had been taped (bypassed) to prevent the automatic shutdown of the feed system if the discharge tube should dislodge during operation. The tape on the Une 3 limit switch resulted in UO powder being discharged from the confines of its analyzed process system. There 2
had been no approval from a shift supervisor or other licensee management authorizing the taping of the switches. Taping of these limit switches is also identified as an apparent violation of License Condition No. 9 (70-1257/93-03-02).

SUMMARY
OF SPC RESPONSE TO APPARENT VIOLATION 2
-Apparent Violation 2 (Taping of Limit Switches)
SPC concurs with procedural violation.
Taping was a licensee-identified condition.
Licensee's report of powder spill under NRC Bulletin 91-01 identified switch taping.
Immediate and long-term corrective actions have been applied.

l NRC INSPECTION REPORT NO. 70-1257/93-05 STATEMENT OF APPARENT VIOLATION 3 The AIT concluded that as of February 12,1993, the licensee had not carefully evaluated the potential for moderator intrusion into the chemical conversion Line 2 unfavorable geometry powder preparation systems from nearby systems containing moderating materials. Specifically, the licensee could not provide any technical basis for the assertion that the moderating liquid systems did not pose a criticality safety concern in the event of a spill of UO powder into the lexan enclosures such as 2
occurred on February 7,1993. In addition, the licensee could not provide any justification that nearby moderating systems did not pose a cri'.cali. safety concern relative to the design and operations associated with the UO powder vacue i transfer systems. Failure to perform such an evaluation is 2
identified as an apparent violation of License Condition No. 9 (70-1257/93-03-03).

SUMMARY
OF SPC RESPONSE TO APPARENT VIOLATION 3 Apparent Violation 3 (Moderator Intrusion Analysis)'
a SPC does not concur with apparent violation.
i-Apparent violation does not recognize existing technical bases underlying moderation control.
Criticality safety analyses for power preparation process equipment Criticality safety specification for moderation control areas Criticality safety review on ECNs for hoods and vacuum transfer systems Apparent violation represents citing of condition for which corrective action pursuant to prior enforcement, action was already underway.

SIEMENS Important Developments in 1992 SPC-NRC Management Meeting NRC's perceived SPC weaknesses:
Inadequate management oversight of safety programs Safety staff too small HPTs not proactive enough NRC Bulletin 91-01 reporting procedure instituted by SPC SPC has taken a proactive approach:
SPC made three reports prior to NRC approval of the procedure SPC errs conservatively in determining reportability SPC major initiatives to upgrade compliance program Review criticality safety program Improve configuration control Improve incident investigations Make needed organizational / staffing changes
SIEMENS Maior Initiatives As a result of SPC-NRC Interactions in 1992, the following areas for improvement are in progress:
Criticality Safety Analysis (CSA) update program
, Review and verify assumptions Identify and document additional accidents Ensure double contingency principle applies Configuration control Improve documentation of changes Upgrade training Incident investigation Improve timeliness Formalize methods Organizational / staffing changes Improve management oversight Increase safety staff
SIEMENS Criticality Safety Analysis Update Program Three phase program to review and update, as necessary, SPC's existing criticality safety analyses.

CONCLUSION l
Siemens Power Corporation's response to the event has been timely, appropriate, and effective. Our recent actions and program initiatives are clear evidence that we are not reluctant to make necessary changes to improve safety or address compliance issues. We have undertaken significant programs to strengthen our staff, to upgrade staff training, increase management control, and to bring about
" cultural" changes.
Escalated enforcement is not merited by NRC criteria. Enforcement sanctions are not likely to enhance our resolve or ability to make improvements. Enforcement-related activity has and would divert valuable resources away from the tasks at hand.
