I I l NOTE: SCBA may be used for respiratory equipment require-l [ ments at the direction of the Emergency Director. l I 4.7 Perform the following checks on the survey meter (s) prior to departing the OSC: (1) Assure current calibration date. (2) Perform a battery check. ,(3) Perform a source response check. 4.8 Allow meter (s) to stabilize and zero meter (s) if 'Hecessary. 4.9 Ensure survey meter is on and instrument is on the highest range. 4.10 Proceed to the applicable area to commence surveys, and scale down on the survey meter until an on-scale reading is obtained. 4.11 Continuously monitor while enroute to the area to be surveyed.

Personnel shall use all l l available ALARA concepts to maintain radiation exposure within the l l guidelines of F3-12, " EMERGENCY EXPOSURE CONTROL", when using this l l procedure to manually determine radioactive release concentrations. l l l l l l l l l l l NOTE: The radiological controls specified in this procedure are l l l l applicable only when there are indications of fuel damage. l l l l Normal radiological control practices should be used if l l l l there is no fuel damage indications. l l l l l l l l l l l 2.0 APPLICABILITY l l l l This Instruction SHALL apply to the Radiation Protection Group, the l l Shif t Supervisors and the Emergency Directors. l i l I l 3.0 PRECAUTIONS l l l l (1) The safety of the personnel performing the evolutions in this l l procedure is the first priority. l l l l (2) If, for any reason, the survey equipment should fail to function ] l properly or go off scale, all personnel SHALL return to a safe l l area. l l l l (3) Periodically check dosimeters and if an individual reaches the l l maximum authorized exposure, immediately return to a safe area. l l l .I I l l l l l IBM l

I l l NOTE: The respiratory protection, protective l l clothing, and entry routes of this pro-l l cedure are not required for Notification l l of Unusual Event, Alert and some Site l l Area Emergency classifications.

If high radiation levels exist, entry should be made via the D-3 room if a Unit I accident, and via normal Access Control if a Unit II accident. 5.1.6 Continuously monitor the radiation levels and record the results or report results to the Radiological Emergency Coordinator (REC). 5.1.7 Upon entry into the Auxiliary Building, or at a specified location, activate the Scott Air Pak. 5.1.8 Proceed to the AM-2 remote monitor located by the BCMS Panels. 5.1.9 Turn the selector switch to the appropriate steam line and record the dose rate. Report results to the REC. ~ 5.1.10 If the AM-2 is not operational, notify the REC. 5.1.11 Exit the Auxiliary Building and remove protective clothing at the Auxiliary Building interface. 5.1.12 The REC should record survey results on Part I of Figure 1 (PINGP 641), then calculate the total steam release flow rate (R) and the release concentration (C) in pCi/cc Xe-133 equivalent, as per the following steps: (a) Eetermine the number of valves (atmospheric dumps, PORV's and safeties) that are open and estimate the total open time, in minutes. l NOTE: The time that each valve stack is l l above 230 F is equal to the valve l l open time.

The Recall System l l may be used in either of two modes, real time or delog l l operations. -In the real time mode, current plant behavior 1 l

may lie monitored.

When an event occurs, the tape handling l l system automatically saves recorded data from approximately l l one hour prior to the event to approximately nine hours l l after the event.or until the event alarm is reset. These [ l . tapes may_ then be delogged to codpile analytical information l l or-to observe plant transcient behavior. l ( l 1 l The purpose of this procedure is to describe'~ the operation l l of the Data Recall Computer System, in both the real time l l and the delog operation. l l l l l l 2.0 APPLICABILl'ij( l 1 I l This instruction shall apply to system engineers in the l l operations engineering group. l l 1 1 1 l 3.0 PRECAUTI;OES l l l l 3.1 Ensure that the tape handling system is checked l .l frequently and the taoes changed to ensure that l l critical data is not lost due to full tapes.

1. If the same tapes are to be delogged further, type

"$", press " RETURN" and repeat step 4.3.9.

2. If new tapes are to be delogged, type "1", press " RETURN" and repeat step 4.3.6.

3. If delog operations are to be termi-nated, go to step 4.3.15.
