REACTOR OPERATIONS MARCH 9 & ' 1981 MARCH 10, 1981 One of the items in Bulletin 80-17 was a requirement for plants to have ATWS operating procedures.
I&E conducted a survey of all operating reactors and procedures were inspected for their acceptability with regards to responding to ATWS events. Mr. Mills reported that all BWRs i
were found to have acceptable procedures. Mr. Mills concluded that as result of the Bulletin, corrective actions had been taken to ensure that the SDV is maintained empty and ready to receive water from a scram during power operation. Corrective actions taken are necessary and sufficient to justify continued operation. Long term action to improve the scram system is necessary and will be performed.
Mr. Schwenk of the ISE Staff discussed the results of the survey to deter-mine the adequacy of licensee emergency operating procedures to respond to an ATWS event at PWRs.
Guidance was supplied from IAE headquarters to the resident inspectors in the form of guidelines to compare ATWS pro-cedures against. The results of the survey indicated that 20 plants had procedures with no exceptions to the inspection requirements. Five plants meet the inspection requirements, but did not have them labeled as specific ATWS procedures. Twenty plants had some minor exceptions to inspection requirements.
