.I.- : Modi fications -

'A". Refuelings-The unitstwo' refueling outage that-started-in 0ctober 1988'end'ed in December'1988. Fuelswas loaded in 1988.

LUnit one refueling outage started in February 1988:and ended in May

'1988, fuel was loaded in 1988.

- 8. Modi fi cations -

Four reportable modifications were completed and verified 'to' operate .

properly. The modifications are: q

1. Modification Description - M22-0-86-17

' Provide raised center' desk in. Control Room. This modification raised.the center desk area approximate 1y'1 foot and gives the

• m Station Control Room Engineer clear view of:both control boards and provides for more effective routing of personnel-traffic in the Control Room. . Spaces for computer terminals,. files and' table space were incorporated into the design. This-Modification satisfies DCRDR HED'0010, 0011, 0216 and 0298.

. Safety Evaluation Summary This-Modification is non-safety related,: non-EQ, but cabinets and raised floor supports are mounted seismically to the existing floor. This Modification does not interact.with'any.

system that is safety related and does.not involve any Tech .i Spec or FSAR issues.-

2. Modification Description - M22-0-87-11 1

Manual-switches in gas analyzer cabinet. This Modification permanently li.fts the leads to solenoid valves on the sample lines to Unit 1 and 2 VCT's because the sample valve can be opened inadvertently by hitting adjacent buttons on the panel.

Safety Evaluation Summarv -)

.The lifted leads make the system safer by preventing-inadvertent release through sample valves of radioactive waste gas. .VCT gas space sampling is not addressed in the Tech Spec's.

3. Modification Description - M22-1-84-04

Modify Rx trip breakers per NRC Reg. and HOG recommendations. )

This Modification does not alter the existing reactor protection, but' adds the auto shunt trip capability. The reactor trip breaker' shunt coils were replaced with qualified coils.

Safety Evaluation Summary

- .'This-change adds extra protection features'. If more breaker cycles lare. required for testing, then it is:possible that the' ,  !

breakers will have to be replaced more frequently. However, this should not. impact breaker performance. . This'changelis being-done compatibly with previous existing features. c

4. Modification Description - M22-1-86-23 s

Eliminate points on by-pass and permissive. :This Modification satisfied NRC concerns related .to DCRDR HED-172, 348, & 369; .

j.

requiring simplification and reduction of Unneeded Annunciation  ;

on the bypass and permissive Annunciator' Panel-on the Unit 1.

Control Board. The remaining Annunciation on this Panellwill be changed to the Dark Board Concept.-

, .Safetv' Evaluation Summary This' Modification-.only involves Annunciator alarms, which does not affect FSAR accidents nor Tech Spec basis margin of Safety.

II. Tests The only testing conducted was done per Tech Spec requirements which involved Performance Testing and Surveillance Testing as required by Zion Station Technical Specifications.

zIII.-Experiments:.

.There were no experiments conducted that involved'a change in the

' Technical Specifications or unreviewed safety questions.
