3.8 INSTRUCTIONS

3 ~ 1 Control Room 0 erators 3 ~ 1 ~ 1 Control Room operating personnel, in addition to submitting a A-25.1 "Unusual Event Report", shou3;d prepare a written account of the event. This account is intended to be written from memory and therefore should be written as soon after the event as practical. Upon completion of the written account it should be forwarded to the Shift Supervisor.

3 ~ 2 Shift Technical Advisor 3~2~1 The Shift Technical Advisor shall perform a preliminary assessment of the event. This shall be documented by completion of the supplement to A-25.1 "Unusual Event Report." Upon canpletion of the supplement, forward it to the Shi ft Supervisor for inclusion with the A-25. 1 Report. The Shift echnical Advisor will also, upon request of the Shift Supervisor, assist with the Shift Supervisor's assessment.

0 A-25.4:2 3 ' Other Plant Personnel 3 3~1 Any other plant personnel that are involved with the event (Auxiliary Operators, ISC,Techs, Electricians etc.) should

~

make notes of their activities related to the event. These notes shall be forwarded to the Shift Supervisor.

'T~g 3.5 Dut En ineer The Duty Engineer shall review the Shift Sup rvisor' assessment of the event. If the computer post trip review printout is available it shall also be reviewed. The Duty Engineer shall make an assessment of the cause of the event. The Duty Engineer shall forward all materials, including his assessment, to the Plant Superintendent.

3.6 Plant Su erintendent 3 ~ 6.1 The Plant Superintendent shall schedu1e a meeting of the Plant Operations Review Committee (PORC) with the purpose of reviewing the event.

3 ~ 7 PORC 3 7.1 PORC shall review the event and either concur with the assessment

~

presented to it cause of the event.

or initiate its own investigation into the 3.8 0 eration Mana er Operation Manager or his alternate shall review this material and concur with PORC's assessment prior to taking the reactor critical.

A-25 ':3 Corrective Actions Any member of the plant staff may initiate corrective action by bringing the matter to the attention cf plant management or the Shift Supervisor.

3.9 ' The plant shall not be made critical after a trip until the event has been reviewed and the cause is known.

4.8 RECORDS

4' Records of the review shall be noted in the minutes of the PORC'

' The PORC minutes shall be the permanent record of the review.

1.2 POST-TRIP REVIEW DATA AND INFORMATION CAPABILITY 1.2.1.1 On-off indications are included in the sequence of events report which is generated by the Westinghouse Prodac 250 Sigma 2 Version Plant Process Computer.

1.2.1.2 The following parameters are monitored by the plant process computer for the sequence of events report.

Generator Output Breakers 1G1372, 9X1372 Grid Breaker 91102 Pressurizer PORVs Instrument Bus Inverters (A 6 C Instrument Buses)

1.2.1.4 The format of these items on a sequence of events printout is shown on Attachment lA, Figure l.

1.2.1.5 Since the data is recorded on a hard copy, it can be retained virtually indefinitely.

1.2.1.6 The normal source of power for the computer is three phase power from a static switch, which receives its power from an inverter. This inverter is fed by a battery charger which receives its power from Class IE Motor Control Center 1K. In the event power is lost from MCC 1K, power is supplied to the inverter by a battery which normally receives a charge from the charger. In the event of an inverter failure, the static switch receives its power directly from MCC 1K.

1. 2. 2. 1 The plant computer, strip charts and multipoint recorders are used and have the capability of aiding in the assessment of the time history of analog variables which are needed to determine the cause of unscheduled reactor shutdowns.

1.2.2.2 The following parameters are monitored for the pre/post trip review by the computer at an interval of two seconds.

NIS Power Range Turbine First Stage Pressure Gross Electrical Output Reference Temperature The following parameters are monitored for the pre/post trip review by the computer at an interval of eight seconds.

1.2.2.3 A time history of 18 seconds prior to and 18 seconds following a reactor trip is recorded for the parameters which are measured at 2 second intervals. A time history of 2 minutes before and 3 minutes after a reactor trip is recorded for the parameters which are measured at 8 second intervals. Data on the strip charts and multipoint recorders is available for an indefinite time both before and after reactor trips.

1 .2.2.4 The format for displaying data from the computer for post-trip reviews is shown on Attachment 1A, Figures 2 through 7.

1.2.2.5 Because the data listed above is produced on a hard copy, it can be retained for an indefinite period of time.

1.2.2.6 The power sources to the multipoint and pen recorders is supplied by the four Class IE instrument busses.

1.2.3 Other Data and Information available assess the cause of unscheduled reactor shutdowns are:

1) 'Alarm typewriter printout

2) Trend typewriter printout

3) Log typewriter printout

4) Analog Pen Recorder Charts

5) Multipoint Recorder Charts 1.2.4 Experience has demonstrated that sufficient data is available following an unscheduled reactor trip to properly assess the cause. RGSE is currently expecting to replace the plant process computer in 1985. This new computer will provide at least as much information as the current system.

2. 1 EPJIPMENT CLASSIFICATION AND VENDOR INTERFACE (REACTOR TRIP SYSTEM INTERFACE)

We have confirmed that the reactor trip system components are classified as safety-related. The general system for classification of safety-related structures, systems and components is through Appendix A (Attachment 2) to the Ginna Quality Assurance Manual and its referenced color-coded draw-ing.

This document contains guidance concerning the designation of safety-related structures, systems and components for the plant. An expanded listing of safety-related items is presently under review and is expected to be finalized by the end of 1983. This revised list will more explicitly contain the reactor trip system and will provide the basis for its inclusion in the documents, procedures and information handling systems used at Ginna to control safety-related activities, including maintenance, design changes and parts replacement.

Administrative procedure A-101 (Attachment 3) indicates in general terms that any activity which affects a safety-related function is controlled by the Quality Assurance program. Administrative procedure A-401 (Attachment 4, figures not included) which addresses procurement activities has been included to demonstrate how the more general procedure has been applied to a more specific area.

~The remainder of this section, is answered in the reply to Section 2.2.2.
