Followu on Previousl Identified Items A
Tem orar Chan es to Procedures (Closed)
Open Item (275/77-02; 275/77-09):
Administrative procedure No.
NPAP A-100 has been revised to reflect the words of the proposed technical specifications.
No items of noncompliance or deviations were identified.
3.
IE Bulletin/Circular Followu Circular No. 79-25 Su lement A (Closed)
Supplement A to the Circular discusses additional problems with the Bergen-Paterson strut assembly.
As before, Supplement A does not apply to the plant because no Bergen-Paterson hardwares have been in use in either unit.
Circular No. 80-07 (Closed)
Although the Circular specifically addresses BWRs, the plant staff found it appropriate to review this Circular as well.
Terry Turbines are also used to drive the Diablo auxiliary feedwater pump li l
The review concludes that water accumulation in the turbine's lube oil would not pose any starting problem since its stop valve is normally open and not hydraulically actuated like the ones described in the Circular.
Regular inspections by the Operations Department, inspections required by the PM Program and the yearly lube oil change, it is felt, should preclude the problem at Diablo.
The Chemistry and Radiation Protection Department, in addition, is considering to develop a periodic lube oil analysis program for rotating equipment that will include the Terry Turbines to control the quality of their lubricating oils.
Circular No. 80-ll (Closed)
The staff finds the Circular does not apply to the plant in that the lube oil coolers of concern have their tubes rolled into the tube sheet.
rather than solder sealed.
Circular No. 80-13 (Closed)
The applicable B-8 series fuel handling Operating Procedures will be revised to reflect any Mestinghouse recommendations communicated to the Company.
A.fuel drag force monitor on the manipulator crane has recently been installed with audio visual alarms to help operators during fuel handling operations.
Circular No. 80-17 (Closed)
Mestinghouse, in their letter PGE-4130 of 2/26/&0, feels the water jetting problem has already been eliminated in Unit 1.
The Unit 1 core baffle plate design has edge to edge bolts along the full length of adjoining baffle segments.
Peening was used to reduce the gap between the baffle segments.
klestinghouse is scheduled to modify the Unit 2 core baffle because of its reduceInumber of edge bolts.
The modification consists of the addition of edge bolts along the full length of the corner baffle plates which will make it similar to Unit 1, and peening of the gaps after bolting.
No items of noncompliance or deviations were identified.
Plant Tour The inspectors walked through various areas of the plant on a weekly basis to observe activities in progress; to inspect the general state of cleanliness, housekeeping and adherence to fire protection rules; to check the proper approval of "man on the line, caution and clearance" tags on equipment, and to review with operation personnel the status of various systems in the plan w3 The inspectors noted that the status of the systems and the housekeeping appeared consistent with construction activities.
The reactor cavity is still being maintained as a clean area.
Cleanliness and housekeeping of the plant is still improving.
No items of noncompliance or deviations were identified.
5.
Preo erational Testin a.
Portions of the following tests and operations were witnessed by the inspector:
12.2A2 CS Pump Performance Test 23. 12 Hydrogen Recombiner Preoperational Test b.
Mhile witnessing the above testing (in some tests only parts of the tests were being performed or redone),
the inspector verified that the procedures were technically adequate; the latest revisions were available and approved, the overall crew performance was adequate and, in the case of completed tests, the acceptance criteria were met.
Administrative controls for design change and documentation were followed.
No items of noncompliance or deviations were identified.
6.
Fuel Loadin FL Full Power FP Prere uisites An inspector reviewed one TAP item in accordance with Temporary Instruction (TI) 2514/01 Rev. 2.
The result of this inspection is as follows:
TAP I.C.7 -
NSSS Vendor Review of Low Power Test Procedures.
Summary:
