Dear Mr. Martin:
Attached for your information is the update of the PASS Status Report Summary dated January 26, 1988 As agreed to per telecon 1/15/88, between Masa Nakao and Mr. Mike Cillis of your staff, this update will be the last PASS Status Report Sumary. With the exception of testing during hot shutdown, all PASS testing has been successfully completed, ending the need for future updates.
A copy of this final update has been provided to the Resident Inspectors Office.
Please contact me if you have any questions. Members of your staff with questions requiring additional infomation or clarification may contact Bob Fraser at (209) 333-2935 extension 4364 or Masa Nakao at extension 4916.

ATTACHMENT 1 PASS STATUS REPORT SUMARY The PASS is designed to sample the following three items:
1)
Reactor Building Atmosphere 2)
Decay Heat System 3)
Reactor Coolant System The Reactor Building Atmosphere sampling capability was tested by STP (Special Test Procedure) 432 and verified the system functioned properly. The test results have been approved.
The Decay Heat System sampling capability was tested by STP.430 and the test results have been approved. The test demonstrated the ability to draw a Decay Heat System sample, analyze the sample for boron and chloride, dilute the sample and transfer the sample to a grab sample flask and the Intrinsic Germanium Element (IGE). The inline conductivity and pH instrumentation were tested by STP.1131 (Liquid Sample Depressurization and Total Gas Test).
STP.1131 test results have been approved.
The Reactor Coolant System sampling capability will be tested by STP.433 at hot shutdown by drawing a sample from the pressurizer. The primary purpose of this STP is to demonstrate the ability to cool an RCS sample. The ability to depressurize and degas a liquid sample was tested by STP.1131.
SYSTEM MODIFICATIONS All Engineering Change Notices (ECNs) are closed.
TESTING With the exception of STP.433, all PASS testing is complete.
STP.1136 (PASS Reactor Building Atmosphere Sample Six Cycle Test) and STP.1137 (PASS Liquid Sample Six Cycle Test) were successfully performed to demonstrate the operability of the system. As a result, the NRC has closed item 86-37-01 on the PASS.

CHEMISTRY PROCEDURES There are five Chemistry procedures associated with the PASS.
All have been approved.
TRAINING All Chemistry Technicians have received four hours of formal classroom training. Six Chemistry Technicians have been trained on the operation of the system with the exception of drawing a high pressure sample.
Completion of this training will occur at hot shutdown.
PREVENTATIVE MAINTENANCE The PM program development is complete.
SPARE PARTS Spare parts are on order.
