--.___ g iew of RMS Task Force Recome tions Items listed below 3re taken from Section V, Recommendations of the 'Paport of Investigation into THI-1 Radiation Monitoring System" dated 10/3/74, S&L-2674 Item Status 9

1.

Acceptance tests for TMI Unit 2 RMS shoulo take place at least crie year X

prior to Unit 2 startup and the system equipment and procedures should be debugged prior _ to plant startup.

Acceptance tests presently are being written by Burns and Roe. They must be reviewed by the TMI staff one and one half years prior to TMI-2 startup.

2.

The Unit 2 RMS warranty period should becin at the time all units have X

passed their acceptance test.

This item is not a pertinent issue since it is impractical to change the Victoreen contract at this time.

3.

The Unit 1 RMS acceptance test should not be used for Unit 2 prior to X

being revised in light of present knowledge. Messrs. Orlandi and Ruth should work on this revision. Then the tests should be sent to Victoreen i

with a request for them to thoroughly leview and cement on the tests.

The acceptance test review route has not, as yet, been established.

4.

The quarterly RMS calibration procedure (1302-3.1) must be imediately X

revised in light of present knowledge. The recommendations of J. Ruth ~

dated 7/15/74, should be incorporated imediately. The 137Cs source should be used in calibrating the iodine monitor window. Refer to the memorandum from S.W. Porter, Jr. to V. Orlandi of 9/20/74. Quarterll/

calibrations should be conducted as soon as possible. The procedurc should require in place calibration and imediate steps should be taken to ensure that as sample chamber become contaminated alternative pro-cedures or replacement chambers are available. This procedur? must allow for immediate re-adjustment of channels found out of calibration.

As noted in Part VI TMI Staff Follow-uo of the RMS Task Force report dated 10/3/74 S and L 2674, the quarterly calibration procedure was immediately revised incorporating the J. Ruth recommendations dated 7/15/74. The 137Cs source is being used to calibrate the iodine monitor window. Quarterly calibrations were promptly performed in accordance with the revised procedure which does require in-place calibration and decon-tamination of the monitor. The procedure provides for immediate re-adjustment of channels found out of calibration. A new replaceable liner chamber has been installed in RML-6. A new replaceable liner for L-6 has been ordered.

E (4) Assessment of Internal Deposition of Radionuclides - all items X

incorporated into axisting procedures except for "quicksort" NaI crystal count procedure.

Sept. 12 Memo All itens complete except for arrangements for a backup counting lab.

X This item has been referred to R. DuBiel for action. This is an emer-gency plan item, and as such, the item is considered complete for pur-poses of the RMS Task Force.

11. The present condition of RMA2 continuously alarming (apparently on redon)

X must be investigated and correct intnediately in order that the system may be capable of performing its intended function. One possible solution is an alpha monitor to read out gross alpha and beta / alpha ratio. This will show rission products in high radon-thoron environments.

This condition has apparently been satisfied by procedure.

12. The TMI-1 Technical Specification requirements for surveillance of the X

RMS channels should be reviewed to deternine if all channels should be included. Channels not directly associated with LC0's should not be included in T.S. Surveillance requirements. All LCO's involving RMS channels should clearly state action to be taken if the channel is inoperable. The inconsisuncies between Appendices A and B of the T.S. with regard to RMS surveillance chould be resolved in a T.S. change request and the terms check, test and calibrate should be defined in Appendix B (or reference made to the definitions in Appendix A).

This item has been resolved for the present by Technical Specification Change Request.

It is expected that the standardized technical specifications, when implemented for TMI-1, will satisfy the full task force reconinendations to provide altematives to the RMS system such as portable monitors, etc.

13. The importance of RMS and especially those channels associated with X

Limiting Conditions for Operation of the T.S. needs to be emphasized to shift operating personnel. Meter readings and recorder chart printout should correspond and discrepancies corrected quickly. All abnormal situations (source checks, releases, etc.) should be annotated on the recorder charts.

Discussions en 10/29/76 with the shift supervisor and control rocm person-nel showed the folicwing:

1.

A procedure stipulates that every 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> ar operator compare the RMS meter reading with the strip chart recorder.

' Status Ra 8 W T"

15 The RM-A2 sampler has been working properly since September 1974. A change mod is being made to minimize a moisture problem in the samoler.

The performance of the RM-L7 pump (SRP-4) has been less than adequate.

The RMS spare parts are more than adequate at this time.

RM-L7 motor was changed in mid 1975 and has performed satisfactorily.

19. The review of and response to QC audit findings needs to be upgraded, X

and all QC non-confonnance items should be checked to detemine if T.S.

violations are involved.

20. A system for marking and storing RMS (and other) recorder charts should X

be developed. The system should pemit location of specific past data

{

without having to search more than one role.

Chart storage is still not adequate. A person should be assigned to the storage area one to two days a week to provide a better method l

of transfer of charts from the control room, to establish chart accountability, to perform inventories and to administer a check-out program to account for charts borrowed by engineers performing studies.

i A long term chart storage program must be established now. These records must be retained, in many cases, for the life of the station according to technical specifications.

21.

TCN procedures should be reviewed for effectiveness and all involved X

should be re-briefed on the proper handling of TCN's.

The review cc::mittee is satisfied that this item has been accomplished.

l

22. The committee recommends periodic (every few years) cross-calibration X

of the gas monitors (RMA8 and RFA9) with NBS gaseous sources and the TMI calibration sources.

The review comittee recommends that this calibration be performed of..a rather than on a periodic basis. This calibration should be perfomed be-cause the Victoreen calibration of the gas monitor was not performed in place, nor with many of the major radiorelease nuclices.

23. A shield should be instr.lled around the Ge-Li deteutor.

X The Shield was installed as noted in Section VI of the original report.
