NRC Docket No. 50-254

  • Reference (a) : R. F. Janocek letter to T. A. Ippolito dated May 21, 1979

Dear Mr.* Ippolito:

Enclosed for your use is a corrected Page 1 of the subject startup test report transmitted to you by Reference (a).

This page should replace the page previously transmitted and includes corrections to the referenced Technical Specification sections and the specified control rod drive insertion times for 90% travel.

Please address any questions you may have con-cerning this matter to this office.

Very truly yours, Robert F. anecek

1. Control Rad Scram Tiain:

Purpase Thc purpose of this test is to d2monstrate the screm capabilicy of ali of the operabic ccatrol rods in ccmoliance with Technical Speci f i c a t i ons '3. 3.C . t c nd 3. 3.C . 2.

Crireric ,

A. The average scran insertion time, based on the de energitatico of the scran pilot valve solencids as tiac zero, of all operable control rods during reactor po.;er operation sball be no greater than:

% INSERTED FRos AVG. SCRAM IM5ERT10N FULLY '.ll TM93 A.si TIMES (sec) 5 0 375 20 0.900 50 2.000 90 3 500 The average of the scram insertion times for the three fastast control rods of all groups of four reds in a two by two arcay shall be no greater than:

% INSERTED FROM AVG. SCRAM INSERTIC?l FP LY WITHn' TI TIMES (c2c)

- 5 0 393 20 0 934 50 2.12c 90 3.300 If these tines cannot ha net, the reactor chall not be made supercritical, if operating the reactor shall be shu tdc',n irr2diately upon determination that average scr,n tima is deficient.

B. The maximun insartion time for 90i insertion of any operable control rod shall not exceed 7.00 teconds. If this requira ent cannot be met, 'tha deficient centrol rcds shall b2 considered inoperable, fully inserted into the core, and electrica!!y disarned.

.R e_ s u l t s and Discussion There were 177 control reds scram tested. The ncximum 007:
