South Texas Project Electric Generating Station-Units 1 and 2 Docket Nos. STN 50 498, STN 50 499 Revised Response to NRC Emergency Preparedness Exercise Weaknesses (498/9010 02. 03. 05! 499/9010 02. 03. 05)

Pursuant to agreement between the NRC staff and Houston Lighting & Power Company (HMP) representatives at a meeting held August 30, 1990 HMP submits the attached changes to our response to Inspection Report 90 10 by letter dated July 11, 1990 (ST IIL AE 3497). The changes affect HMP's response to Emergency Preparedness Exercise Weaknesses 9010 02, 03, and 0 Revisions are highlighted by chang, bars, llMP understands the importance of correcting the identified weaknesses and will fully address each issue prior to ,

completion of the Emergency Preparedness Enhancement Progra An issue was discussed at the August 30, 1990 meeting regarding HMP's inability to resolve NRC comments on the 1990 Craded Exercise prior to the exercise. NRC had substantial comments on the scenario, and H MP was unable to address these comments adequately because they were not received until the day before the . exercise. To alleviate this problem in the future, HMP proposes to :chedule a meeting with the NRC sufficiently before the exercise to review '.he scenario. This will enable llMP to ensure NRC's cottments are addresse If there are any questions, please contact either Mr. V. A. Simonis at ($12) 9'i2 8330 or myself at (512) 972 853 >

is responsible for ensuring habitability checks are performed in the control Room. Because the plant simulator located in the Nuclear Training Facility (NTF) was used for the exercise Control Room, the TSC Radiological Manager was uncertain where to send the Health Physics (HP) technicians to perform the habitability check During future drills using the sirsulator, the TSC drill controller will direct the TSC Radiological Manager to send the i

HP technicians to the affected unit Control Room to perform habitability check Performance of Cantrol Room habitability checks will be demonstrated during the 1990 and 1991 emergency drills and exercise ch - WC6- "

Units 1 and 2 Docket Nos. STN 50 498, STN 50 499 Revised Response to NRC Emergency Preparedness Exereine Weaknamaan (498/9010 03t 499/9010 03)

.

I Weakness Poor radiological practices and failure to follow the radiation protection procedure were observed in the process of determining habitability in the TS .

o The air sampler was not made functional until 10:34 a.m., although the first radiation habitability survey was logged at 8:55 This contradicts paragraph 1.1, Addendum 1 of Procedure OEPP01.ZA 0005, "Onsite Radiological Controls," which requires air sampling as one of the conditions for establishing habitability in the TS !

o Self reading dosimeters were not issued to the TSC staff. The number of self reading dosimeters was not consistent with the number of personnel requiring radiation monitoring protection in the TSC. Only six low. range and six high range dosimeters were available in the facility, o The TSC ventilation was not shifted to a recirculation mode-until 11:36 a.m., approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> after,the simulated release of radioactivity to environs had been detected. Apparently, the .

licensee's policy is for the TSC_to remain in normal ventilation line up until unacceptable levels of radioactive contamination are sensed in the induction air plenun. This could load to unnecessary inhalation of radioactive' contamination by members of the TSC .

staf ,

1 Resoonse Adder.Jum 1 of procedure OEPP01 ZA 0005 addresses emergency accumulative exposure limits. Addendum 8, paragraph 1.1 of the same procedure states initial habitability checks (including air' sampling) shall be performed if a release of radioactive material has occurred or is in progress at the time the facility is activated. Reccrds indicate the l release of radioactive material began at approximately 10:30 a.m.-

Although the habitability check was not required until 10:30 a.m., an air sample should have been performed as part of any habitability survey logged as completed prior to 10:30 a.m. Procedures will be-revised to clesrly specify when air samples-are to be taken fr.r- I habitability checks and appropriate plant personnel will be instructed .

Automatic isolation of the.TSC HVAC system will occur following detection of high levels of airborne radiation, toxic gas, or smoke in the intake. Manual activation of isolation is also possibl However, review of the TSC HVAC operational philosophy and design indicates there is no method for remoce operation or remote system alignment indication currently available. Therefore, emergency procedures will be revised to reflect the following: , If an emergency is declared and there is no potential for a radioactive release, then the TSC HVAC will be left in the normal system alignmen : If an emergency is declared and a potential for a radioactive release is found to exist, plant personnel will be dispatched to ,

Revised Response to NRC Emergency Preparedness Exercise Weaknemmes (498/9010 0$! 499/9030 05) Weakness The locations of all missing persons within the protected area were not established within 30 minute ,

1 Response STPEGS defines ' Accountability" as the process of verifying the general location of essential and non essential personnel inat4e the Protected Area (PA). Persons whose location inside the PA cannot be verified  ;

'

within 30 minutes are classified as " missing *.

The goals of Accountability at STPEGS are to: Verify the location of essential and non ess'ential personnel inside the PA within 30 minutes of sounding the Assembly alar ; Determine the names, PA badge numbers, and_last known location of missing persons inside the PA within 30 minutes of sounding the Assembly alar Current procedures and training do not consider performing Accountability prior to activation of the Emergency Response Organization. HL&P procedures will be revised and personnel instructed i that Accountability is initiated immediately upon sounding the Assembly l alarm. Performance of Accountability will be optional following declaration of a Notification of Unusual Event or an Alert, but mandatory following declaration of a Site Area Emergency or General Emergenc If missing persons are identified during Accountability, Searah and Rescue at STPECS will be initiated following Accountability. Search and Rescue at STPECS will consist of public address announcements, search of the PA badge racks, and field teams searching buildings and I structures within the PA. Field teams will be dispatched from the

'

Operations Support Center (OSC) to search for the missing person Following Accountability, the numberfof missing persons will be

, acceptable provided the OSC can dispatch an adequate number of' field teams used for Search and Rescue to locate all missing person The actions described above will be completed land an Accountability drill conducted no later than December 31, 1990. Future Accountability drills will be scheduled based on tho' success of this dril Note that the difficulty of performing Accountability will be reduced by-new office facilities currently under construction outside the PA which will reduce the number of plant personnel inside the P t h$8h$O NlO
