Summer Nuclear Station Docket No. 50/395 Chapter 14 FSAR Tests

Dear Mr. Denton:

Several changes to FSAR Chapter 14 were discussed with Mr.

William Long of your staff on July 7, 1982. These changes involve FSAR Tables 14.1-58, " Reactor Coolant System Flow Measurement",

and 14.1-75, " Rod Drop Test".

Please find attached these " marked up" pages which contain the changes as agreed to by Mr. Long.

If you have any questions please let us know.

Very truly yours, 77

TABLE 14.1-58 REACTOR COOLANT SYSTEM FLOW MEASURE >ENT 1.0 Objective i

Obtain the data to compute actual reactor coolant system flow rates as they relate to the design flow rates.

2.0 Prefequisites 2.1 Core installed.

2.2 Reactor plant is in hot standby condition with all control rods l

15 fully inserted.

2.3 Reactor coolant pumps operable.

3.0 Test Methods 6

3.1 Measure loop temperatures, loop elbow tap 6p's and reactor coolant pump input power and speed for various configurations of reactor coolant pumps.

3.2 Compute actual reactor coolant system flow race. Density vari-ation of cold leg fluid will be accounted for in the data 15 reduction method to provide direct comparison to full power conditions.

4.0 Acceptance Criteria i

(l Reactor coolant system flow rates are determined to be greater than I

i or egual to the thermal design minimum and less than or equal to s

the mechanical design maximum as per FSAR Table 5.1-1.

1.0 Obj ect ive 4

To demonstrate the operations of the negative rate trip circuitry in detecting the simultaneous insertion of two cluster control assemblies.

30 2.0 Pre requis ite s 2.1 All power range nuclear instrumentation channels are operable.

2.2 The reac tor is at the steady-state power level specified in the procedure with the controlling bank near the full power inser-tion limit.

2.3 Pertinent parameters to be measured are connected to recording device s.

3.0 Te s t Me thods S.E,% r Two rods from a common group most difficult to detect by excore i

de tectors due to low worth and core location, are simulta-l 30 neously dropped by removing voltage to both the moveable and 15 l

stationary gripper coils of the designated rod.
