1. NAVAL REACTORS PROGRAM TMDE Status Gregory L. Nelson NAVSEA 08 (202) 781-6177 Gregory.l.nelson1@navy.mil

2. NAVSEA 08K • Responsible for the development, manufacture, installation, testing, operation, and maintenance of: • Reactor Plant I&C equipment and systems used to monitor and control the reactor plant. • Steam and Electric Plant I&C equipment and systems used to monitor and control the main engines and electric plant.

3. Background • What are we trying to fix? • Maintenance personnel have difficulties in identifying meter equivalencies • Increasing number of GPETE models called out by 08 procedures are obsolete • Test equipment called out in technical manuals may not have the procedures required for calibration • Equipment technical manuals lacking test equipment definitions

4. Fix: Use the NAVSEA 04 process • Use SCAT codes to call out TMDE, no need for worker to determine equivalency, just pick any current meter from the SCAT code. • NAVSEA 08 will no longer need to track GPETE obsolescence, NAVSEA 04 actively does this in TMDE index. • Formal Communications: All of our measurement requirements are now know by NAVSEA 04, including when SPETE is required. This should eliminate surprises at the Cal Lab. • CMRS data sheets: All measurement requirements are now documented for future use.

5. Big Picture Plan • Step 1 – Formulate plan and get NRHQ approval • Step 2 – Review and update source requirements as required. • Step 3 –Determine measure requirements, assign SCAT codes, and incorporate them into component technical manuals (CTM).

6. Conversion Status –Step 1 Get NRHQ approval for change. • The long term plan to convert the NAVSEA 08 process for determining meter equivalency to the NAVSEA 04 process was approved by NAVSEA letter Ser 08K/05-04118, dated 21 December 2005.

7. Conversion Status – Step 2Update all source requirement documents • The following source document revisions were authorized by NAVSEA 08 on 13 December 2006. • TM-1- Preparation of Technical Manuals for Special Purpose Mechanical and Electrical Equipment • Provides guidance on how to incorporate SCAT codes into manuals. • MIL-DTL-23200- Detail Specification, General Specification for Control and Instrumentation Equipment • Removed Portable Test Equipment List 1A • E-569368-DID-I- Data Item Description for Equipment Hardware Design Documentation • Requires vendor to provide measurement requirements. If required, BPMI completes the CMRS data sheet.

8. Conversion Status – Step 2 • New BPMI Operating Instruction (OI) – EN112 Test, Measurement & Diagnostic Equipment • Provides relevant TMDE definitions • Identifies how to complete a CMRS form • Details the interface with NAVSEA 08 and NAVSEA 04 • NAVSEA 0989-031-4000 –Reactor Plant Instrumentation & Control Equipment Maintenance Manual • Section G/I 8 - Selection of Equivalent Electrical Meters, Recorders and Oscilloscopes updated to recognize use of SCAT codes.

9. Conversion Status – Step 3 Schedule • Schedules are based by ship class and equipment suit installed (i.e. S8G Type 2, 688 Type 1 ) • Based on remaining service life, not all class manuals will be converted. (i.e. CVN65, NR-1, Analog equipment being replaced by Microprocessor equipment)

10. Conversion Status – Step 3 Conversion Outline: • Applicable system engineers completed part 1 of CMRS data sheets based on Component Technical Manual procedures. To aid NAVSEA 04, current model used was also listed. • It was stressed NOT to base measurement requirements solely on existing model being used. • Completed sheets are provided to NAVSEA 04 by BPMI. BPMI co-ordinates any questions from NAVSEA 04 to the applicable system engineer.

11. Conversion Status – Step 3 Conversion Outline: • Once completed, NAVSEA 04 provided completed CMRS data sheets (SCAT code assignment) to BPMI. • SPETE (which may not have been previously identified to NAVSEA 04) is also being assigned a SCAT code to ensure proper support is identified. • BPMI updates the component technical manual to use SCAT codes during next routine manual revision. Any measurement that does not meet a 4:1 Test Accuracy Ratio requires NAVSEA 08 approval prior to use.

12. Conversion Status – Step 3 • First conversion (S8G - Type 2) process is in the final stages of CTM revisions. • Remaining project schedules are being evaluated. Next project being worked is 688- Type 2.

13. Future Projects • Contracts will be written to require the vendor to provide measurement requirements. BPMI will use this data to complete the CMRS data sheet. • CVN78 contracts have been written using the new process. • Type 2 equipment contracts for Virginia and Seawolf classes have also been written using the new process.

14. Summary • Significant progress has been made to date for this effort. • All parties have been participating in bi-weekly telecons to review status and address any issues. • Having completed the first project, all parties are currently looking at lessons learned, and updating processes to make improvements.
