Enforcement Conference Details
,
Mr. Pate summarized the five-apparent violations, described in-Inspection'
' ;
Report 50-529/93-22 involving failure to: (1) classify the March 14,1993
.i steam generator tube rupture (SGTR) event in accordance with Emergency Plan Implementing Procedures (EPIPs), (2)' activate the Emergency. Response Data System (ERDS) within sixty minutes, (3) conduct accountability-
'
within thirty minutes, (4) conduct a check of areas outside of the
_
.
Protected Area (PA), and (5) fully integrate-Emergency Plan requirements -
into the EPIPs.
The licensee agreed with the facts in the inspection report. Mr. Conway
-
'
stated that they had reviewed our reports and that they wanted to look
.
more deeply than just at the potential Violations. Mr. Wiley summarized

'
the licensee's position concerning the classification of the March 14 event and the activation of the ERDS.
During this discussion, Mr.
Scarano questioned the licensee about the appropriate classification for
,
a SGTR event with no other complications such as occurred on March 14.
He also noted that the NRC guidance given in NUREG-0654, Criteria for
'
Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, would classify a SGTR with no complications as an Alert and asked the licensee if Palo Verde was unique in that a SGTR should be a Site Area Emergency. The licensee
stated that their review indicated that an Alert was the proper level of
'
classification for the March 14 SGTR event; however, they would like to make an additional review and would reply to the question during the i
following week.
On June 10, 1993, Harry Bieling, APS, advised Robert Pate, NRC, by telephone that the correct classification for a SGTR. event at Palo Verde is an Alert.
The licensee agreed to revise EPIP-02, Emergency Classification, to reflect the proper classification level.
t Mr. Bieling summarized the licensee's position concerning the time to conduct accountsbility, the checking of the PA, and the EPIP adequacy.
The licensee acknowledged all of the apparent violations except for two of the three examples listed in Inspection Report 50-529/93-22 for the failure to fully implement the Emergency Plan in the EPIPs.
The licensee believed that although the one hour time expectation is not mentioned in the EPIPs for a check of the Owner Controlled Area (OCA) the guidance of
]
"as soon as possible" in a table in an appendix attached to EPIP-20,
Personnel Assembly and Accountability, was satisfactory.
The licensee also believed that the references to search and rescue teams mentioned in EPIPs-11 and 12 were sufficient to implement the Emergency Plan
,
requirement that a search and rescue team be sent for unaccounted I
personnel. The licensee stated that during the March 14 event station security personnel searched for unaccounted personnel. Mr Bieling also summarized the training activities, procedural changes, and unannounced accountability drills, which had already been completed or scheduled as corrective actions for the accountability issue.
During the course of the conference, Mr Bieling presented a summary of the licensee's EPIP-02, Event Classification, revision which was being developed.
Mr. Levine also discussed the Emergency Response Facility (ERF) activation times.
Mr. Bradish presented the licensee's position on mitigating factors for the potential violations. Mr. Conway concluded-that it is management expectations that people follow procedures and that they were taking an in depth look at the NRC's AIT (Augmented Inspection Team) and APS's IIT (Incident Investigation Team) investigations. Mr.
Faulkenberry acknowledged the licensee's efforts and stated that the NRC was most concerned about the assembly and accountability violations since it has been a recurring issue for some years. Mr. Faulkenberry stated that we appreciated the opportunity for open communication.
