B. Assionment: Technical Support Center (TSC)

C. Site Personnel Contacted: J. Rafalowski, TSC HP Coordinator (Red Team);

R. Starrett, TSC HP Coordinator (White Team); A. Merrill, TSC Controller; R. Littman, TSC Controller; D. Moody, Site Emergency Director (SED) (Red Team); W. DiProfio, Site Emergency Director (White Team); G. Kleine, Technical Support Coordinator (Red Team); J. Linville, Chemistry Coordinator (Red Team); and J. Distefano, YNSD Radiological Engineer (RedTeam). ,

D. Positive Findinos e The TSC was manned quickly and efficiently. The SED carefully established plant conditions through discussion with the control room I (CR) staff before declaring the TSC activated and assuming the role of SED.

. The availability of and access to controlled drawings and technical manuals was excellent, e The display of current and past (trended) plant data on status boards ",

was excellent. Key data were promptly displayed in an easy-to-read manner. (However,theradiologicalsurveymapswerenotusedatall.)

e The engineering group actively pursued alternative lineups for .-

f restoration of containment spray throughout the exercise. (However,the l -

quality and workability of some of the proposed lineups was questionable,andnonewasevercarriedthroughtoexecution.)

. The turnover to the oncoming white team was orderly and complete,

( although quite noisy.

)

. The extended dose authorizations were processed in a careful and considered manner for workers to be involved in the completion of the CBS pump repair.

. The YNSD Radiological engineer correctly pursued critical organ dose calculations for the particulate constituents of the release in order to confirm the adequacy of the protective action recommendations based only on calculated whole body and thyroid doses.

E. Negative Findinas

. Discussion of the emergency action levels in force seemed to indicate a 1

basic misconception of the classification / deescalation process on the {

-I part of many TSC staff. (This was later clarified by the white team SED.)

. The noise level in the TSC was frequently excessive due to many separate discussions going on simultaneously with little discipline or control. .

. With the RCS depressurized and a major release still in progress, the j chemistry coordinator requested (and received) permission to take an RCS 1 sample because technical specifications require a sample every four l hours if dose equivalent iodine-131 is greater than 1 pCi/gm or gross N

coolant activity is greater than 100/E Ci/gm.)  ?

. Radiological controls in the TSC during the period of the large release l were at times ineffective. ,

A frisk station was set up inside the main control room door, however a second access door to the control room complex was uncontrbiled.

- No self-reading dosimeters were issued to the red team members, I even though they were allowed to leave the TSC and depart the site j with a large release in progress while the wind was shifting.  !

- The Health Physics Coordinator removed one air sample head and handled the filter cartridge with bare hands, even though some activity had reportedly entered the CR/TSC ventilation envelope.

. No significant effort was directed at locating and sealing the containment leak.

. There was no objective evaluation or discussion of the impossibility of such a huge release following the relatively minor core mechanical damage and thermal transient. (Total release exceeded Chernobyl).

. Effort to find parts to repair the turbine driven EFW pump continued until nearly 1900, even though the EFW system operability ceased to be a consideration in the accident at 1330 when the large break LOCA occurred.

1224 Status update: beaches have been closed. Fire hoses rated at 600 psi have been found for possible cross-connects. Power still trending down, even though controller supposedly stopped the power reduction (Xenon buildup is doing it).

1245 Good status board configuration--good attention to maintenance of boards.

1247 Letdown monitor jumped to 865 pCi/cc.

1404 WRGMS now greater than 109 pCi/sec. 1409 METPAC projection for 1345 release rate is 208 mr/hr WB and 216 mr/hr infant thyroid at 0.6 mi.

1442 Technical Support Coordinator directs survey team be expedited out of OSC to survey site access road.

1447 Briefing by ESD on team relief procedure.

1457 Survey of access road complete. Results of 1423 WRGMS sample received. Projection is ~4 R/hr at 2 miles. Lots of particulate and iodine in the release, characterized as " messy" (also very bio i

-- ~30 million Ci) nobody comments on it! Amazing.

1638 CBSpump9Brepairedandoperating(controlleraction). Simulator asks permission to start it. Some confusion. Work on the alternate lineup is stopped.

1646 Habitability survey by HP Coordinator. Now processing dose extensions for team to go in and finish repair to CBS pump 9A.

1708 SED briefs TSC team. Containment level still dropping slowly, don't know where its going. Review of PARS now in effect, changes in wind direction likely.

1715 CBS pump 9A repaired and operating (controller action). -

1719 Controller says containment sump not really dropping. Simulator artifact.

1726 SED briefing -- cooling down containment with CBS, WRGMS readings coming down. SED says "have deescalated" on the 8d (containment radiation) EAL to 8c (Site Area Emergency) however, still in GE because calculated dose rate at site boundary is 100 mr/hr.
