a. This area was inspected to determine whether the licensee's Emergency ;

Response Facilities (ERFs) and equipment. were adequately maintained in accordance witn the Emergency Plan. Requirements applicable to this area are found in 10 CFR 50.47(b)(8) and (9).10 CFR 50.54(q).

Sections IV.E and VI of Appendix E to 10 CFR Part 50, and the

, licensee's Emergency Pla b. Observations a,nd Findinos The inspectors toured the Technical Support Center (TSC) and Operational Support Center (OSC) and tested telephones, fax machines, and Emergency Response Facility Information System monitors and Computer The inspectors reviewed documentation of tests and audits completed as required for 0-PI-REM-244-001.0. " Periodic Testing Of Emergency Response Facility Communications Equipment " Revision 0, from September 1996 through September 1997. The licensee provided the

'

inspectors a bar chart titled " Equipment Failures Surveillance Identified" that displayed the number of equipment which tested satisfactory and the total number of equipment tested in 0-PI-REM-244 001.0. The bar chart indicated a " good" reliability or performance for the equipment tested. When the inspectors asked the licensee for specifics on which equipment components had failed, the licensee stated that specific equipment failures were not readily available, but the information could be retrieved from document control's microfiche. In ensuing discussions with the inspector, the licensee stated that they did not track or trend specifi ?quipment failures identified in surveillances. This indicated to che inspector that tne licensee was limiting their focus to the overall performance of the system and not including an evaluation of the

, system performance at the component leve The inspectors audited several controlled volumes of the Emergency Plan Implementing Procedures (EPIPs) in the ERFs for being maintained up to date. All of the EPIPs audited were up-to-dat The inspectors uced EPIP 17. Emergency Equipment and Supplie Revision 13. to audit the inventories of three emergency cabinets and the emergency lockers in the TSC and OSC. The equipment tested by the inspectors operated satisfactorily and the emergency lockers inventories were complet _

The inspectors reviewed documentation of completed Appendices (inventory forms) of EPIP 17. from September 1996 through September 1997. _ Although the inspectors found the documentation complete, the inspectors noted examples of lack of attention to details in the inventory forms:

oEPIP 17. Appendix H. TSC. had the licensee verify " SETS" of System Operations Manuals. System Operating Instructions. Annunciator Response Manuals, and Periodic Instructions, that were on the shelves, but neither the Appendix indicated nor the licensee knew how many books were supposed to be in a " SET".

oEPIP 17. Appendix I. OSC. had changed the audit of two Electrical and four Mechanical Emergency Tool Kits from a detailed list of required tools in each bag to simply. "6 Tool Kits and various tools". The licensee stated that the Appendix I was changed as a result of a Quality Assurance audit finding resulting from tool bags not meeting their, inventory requirement " Assorted" was used to specify type and quantity of office and i desktop supplies required in the OSC and TS No significant changes to the facilities were observed by the inspector c. Conclusion The inspectors concluded that the licensee maintained the facilities l and equipment at a satisfactory level of operational readines Equipment performed satisfactorily, Audits of equipment and supplies were completed at the required frequencie The effectiveness of EPIP 17. Appendix 1. OSC inventory audit had decrease In testing of emergency response equipment, the licensee was limiting their focus to the systems overall performance and not including an evaluation of the system at the component leve P2.2 Public Alertino System Insoection Scoce (82701)

This area was inspected to review the licensee's method of notifying the public in the event of an emergency, and the Public Alerting Syste.n test frequency and test data.

3 Observatj,ons and Findinas The licensee maintained 108 sirens within the Emergency Preparedness Zone for their public alert and notification system. The inspc_ ors reviewed documentation from September 1996, through September 1997, for quarterly preventative maintenance on the sirens, bi-weekly silent test, monthly sounding and an annual sounding of the siren The inspector's review determined that the sirens had been maintained and te.sted at the required frequencies. The 1996 Sequoyah Nuclear Plant siren availability report summary indicated a siren availability of 97.9 percent compared to the Federal Emergency Management Agency's acceptance criterion of 90 percen While reviewing the documentation the inspectors noted that siren number 45 had not satisfactorily completed the bi-weekly silent test since October 1996, and siren number 76 had not satisfactorily completed the test since July 16, 1947. The licensee determined that no work request had been written on either siren. The licensee was only reviewing the system availability factor and was not trending which sirens tested unsatisfactoril c, Conclusion The inspectors concluded that the siren system was being satisfactorily tested and maintained. However, sirens 45 and 76 had lengthy histories of consecutive unsatisfactory b?-weekly silent

, tests without corrective maintenance.

The inspectors reviewed the licensee's changes to the EPIPs to evaluate whether changes to the EPIPs were in agreement with 2nd implemented the Emergency Plan. Requirements applicable to this area are found in 10 CFR 50.47(b)(16). 10 CFR 50.54(q), Appendix E to 10 CFR Part 50, and the licensee's Emergency Pla b. Observations and Findinas The inspectors reviewed EPIP 14. Radiological Control Response, I Revision 8, effective date of September 19. 1997. The ability of onshift personnel to perform an offsite dose assessment in the event of a radiological emergency was identified as an issue in Inspection Report 50-327.328/96-04. The inspectors specifically focused on EPIP 14 Appendix E. " Methodology For Projecting Total Effective Dose

Equivalent (TEDE)". Appendix E provided the user two methods of deriving " Plant Total Gaseous Rad Release"; a computer method and a manual method. If the computer was not available. then the manual method was to be used. It was the licensee's expectation that both methods should give the user the same result. On September 21, 1997, a review of EPIP 14 revealed that, if both methods were performed, the computer method was approximately 20 percent iceer than the manual method. A detailed review of Appendix E revealed two major errors in the procedure:

,

l oThe computer method used the dispersion factor (X/0) value from Tl 30 Revision 3. The manual method used the dispersion factor (X/0)

value from Tl 30 Revision oln the manual method. the final calculation of step 4.a. incorrectly applied a multiplier of X1 The licensee could not identify why the errors were not found in the development or review proces The inspectors reviewed EPIP.1. Emergency Plan Classification Matri Revision 23. effective date of July 11. 199 EPIP 1 was the licensee's Emergency Action levels (EALs) based upon NUMARC methodology. The inspectors compared the instrumentation ranges and nomenclature identified in the EALs to the instrumentation in the control room. No inconsistencies were identifie The inspectors reviewed the licensee's event declarations to verify that events were properly classified and notifications were made in a timely manne On October 5,1996, the licensee made a Notification Of Unusual Event (NOUE) emergency declaration when a Potential Transformer in the 500 KV switchyard exploded. The inspectors' review noted the control room had indications and reports of a transformer explosion at 1:13 The fire alarms were secured at 1:37 p.m. and by 1:39 p.m. all control room annunciators were returned to normal. The NOUE (EAL

EPIP Emergency Plan Classification Matrix. Revision 20 which was in effect at the time of the event states in the definitions of an Even " Implicit in this definition is the need for timely assessment within 15 minutes." NRC Emergency Preparedness Position Number 2. Timeliness Of Classification Of Emergency Conditions, dated August 1.1995, states the NRC's expectation on timely declaration as: "The staff

position is that a 15 minute goal is a reasonable period of time for assessing and classifying an emergency once indications are available to control room operators that an EAL has been exceeded." This NRC position was made available to all utilities. A review of Sequoyah's documentation of the event indicated that neither managemen training, operations, nor emergency preparedness had identified the delayed or late declaration as a concern requiring corrective actio '

The inspectors viewod this late declaration as a weakness in the plant's emergency response performance, Conclusion
