.AV) 2.1 Immediately prior to de perfor: nance of this test, the Test Engineer has reviewed de latest revhions of the applicable references in order to improve hit. familiarity of this procedure of the test.

(i.e. Changes to the system, equipment or com-ponent since the procedure was approved will not affect its tesLing.)

[

2.2 7erify that all test equipment to be used in the performance of this test is operational and in calibration, and record on the attached TIST IQUI?ENT DATA SEEIT.

3.1 Care shall be exercised at all times duru g the survey to 7

mini =4 9e dose received by the surveyors. Wenever possible exposure to radiation shall be divided between the members of each survey team so that dose received by each member will be nearly the same.-

[lMA 3.2 Prior to entering any area the survey meters will be read while the surveyors are still shielded ba"d"d existing barriers.

Mb 3.3 The plant should remain a steady state conditions throughout the performance of the survey. If a change in plant power level is required, the survey team must be notified prior to the change.
