TESTIMONY OF MATTHEW C. CORDARO, CHARLES A. DAVERIO, AND MICHAEL L. MIELE ON BEHALF OF LONG ISLAND LIGHTING COMPANY ON PHASE II EMERGENCY PLANNING CONTENTION 77 (THYROID CONTAMIN.', TION EQUIPMENT AT RELOCATION CENTERS)

PURPOSE Contention 77 states that backgrcund radiation levels at relocation centers are likely to exceed 50 cpm and that the ra-diation monitoring equipment to be used at relocation centers is incapable of detecting a thyroid contamination level of 150 cpm in a backcircund radiation field above 50 cpm. This testi-mony will establish that the radiation monitoring equipment to be used at relocation centers will adequately identify those persons with thyroid contamination levels requiring medical at-tention. The RM-14 meter with HP-270 probe can detect l

l radiation levels from thyroid contamination in the range of 150 cpm when the background level is as high as 350 cpm. In addi-tion to the RM-14 with HP-270 probe, an RM-14 meter with a tungsten shielded HP-210 probe will be used at relocation cen-ters within 15 miles of the Shoreham Nuclear Power Station.

The RM-14 meter with a tungsten shielded HP-210 probe can mea-sure radiation levels from thyroid contamination in the range of 150 cpm in background radiation fields exceeding 350 cpm.

2. Q. Please summarize your professional qualifications and your role in emergency planning for the Shoreham Nuclear Power Station.

A. [Cordaro] I am Vice President of Engineering for LILCO.and have held this position since the spring of 1978. My professional qualifications are being separately offered into evidence as part of the document entitled " Professional Qualifications of LILCO Witnesses." I am sitting on this panel co provide the LILCO management perspective on emer-gency planning and to answer any questions perti-nent to management. My role in emergency planning for Shoreham is to ensure that the needs and re-quirements of emergency planning are being met and that the technical direction and content of emer-gency planning are being conveyed to corporate man-agement.

[Daverio] I am employed by LILCO as Assistant Man-ager of the Local Emergency Response Implementing Organization (LERIO). My professional qualifica-tions are being separately offered into evidence as part of the document entitled " Professional Quali-fications of LILCO Witnesses." In my capacity as Asuistant Manager of LERIO, I am responsible for developing and implementing the local emergency re-l sponse plan for Shoreham, i

[Miele] I am employed by LILCO as the Radiation Protection Section Supervisor in the Nuclear Engi-L neering Department. My professional qualifications i

are being separately offered into evidence as part of the document entitled " Professional Qualifica-tiens of LILCO Witnesses." I am responsible for the corporate overview of all technical aspects of onsite and offsite radiological protection for Shoreham. I am familiar with the procedures and radiation monitoring equipment at issue in Conten-tion 77 because I have 11 years of experience in health physics, which has included use of similar i procedures and radiation monitoring equipment.

l

3. Q. What is the "Further Preamble to Contentions 74-77?"

A. [Cordaro, Daverio, Miele] The "Further Preamble to Contentions 74-77" reads as follows:

Further Preamble to Contentions 74-77. An offsite emergency plan must include means of relocating evacuees and must provide for relocation centers lo-cated at least five miles and preferably 10 miles beyond the EPZ. NUREG 0654, Sections II.J.10.g and h. Such reloca-tion centers arp essential to provide food and shelter to those evacuees who have no alte'enative places to stay and also to provide radiological monitoring and decontamination for evacuees and their vehicles. The. relocation centers must have sufficient personnel and equip-ment to monitor evacuees within a 12-hour period. NUREG 0654,Section II.J.12.

The LILCO Plan calls for the estab-lishment of relocation centers outside the EPZ at the following facilities (Plan, at 4.2-1; OPIP 4.2.1):

Suffolk County Community College (primary)

BOCES Islip Occupational Center (primary)

State University of New York at Stony Brook (primary)

State University of New York at

, Farmingdale (backup)

St. Joseph's College, Patchogue (backup).

The Intervenors contend that LILCO will be unable to provide adequate relocation centers and services for evacuees, and thus the Plan fails to comply with 10 CFR Sections SO.47(s)(1), 50.47(b)(8),

50.47(b)(10), and NUREG 0654 Section J.

The specific deficiencies which lead to this conclusion are set forth in Conten-tions 74-77.

4. Q. What is Contention 77?

A. (Cordaro, Daverio, Miele] Contention 77 reads as follows:

Contention 77. The equipment used by LILCO to measure thyroid contamination at relocation centers -- RM 14 with HP270 probe -- (see OPIP 3.9.2) will be incapa-ble of differentiating the required sig-nal from background readings. The in-strument's most sensitive scale (0-500 cpm) is insufficiently sensitive for the accurate measurement of 150 cpm or O.13 mR/hr (the threshold for requiring hospi-tal care) in the presence of background readings which are likely to elevated

[ sic) above the 50 cpm maximum (10-15 cpm

I nominal) assuned by LILCO. (OPIP 3.9.2 and Plan, at 3.9-4). In addition, the j Plan provides no information or instruc-  !

tion on how to make a measurement if the background reading exceeds 50 cpm. Ac-cordingly, the LILCO plan fails to comply with NUREG 0654 Section. II.J.12.

5. Q. What are the legal standards that govern Contention 77?

A. [Cordaro, Daverio, Miele] The legal standaru cited in Contention 77 is NUREG-0654, II.J.12, which reads in pertinent part:

NUREG-0654,II.J.12 Each organization shall describe the means for registering and monitoring of evacuees at relocation centers in host areas.

6. Q. Contention 77 states that an RM-14 survey meter with HP-270 probe will be used by monitoring per-sonnel to measure thyroid contamination levels of evacuees at relocatien centers. Is that true?

A. [Cordaro, Daverio, Miele] Yes. As is indicated in OPIP 3.9.2 of the Plan, an Eberline RM-14 survey meter with HP-270 probe will be used to measure thyroid contamination levels at relocation centers.

The manufacturer's descripcions of the RM-14 meter and the HP-270 probe are appended to this testimony as Attachments 1 and 2 respectively.

l l

7. Q. What is the range of'the RM-14 meter with HP-270 probe?

A. [Cordaro, Daverio, Miele] As can be seen from At-tachment 1 to this testimony, the RM-14 has three ranges: 0-500 counts per minute (cpm), 0-5000 cpm, and 0-50,000 cpm. The RM-14 will be set on the l lowest of these ranges (0-500 cpm) to monitor thy-roid contamination levels at relocation centers.

l

8. Q. What steps must be taken by monitoring personnel to obtain a thyroid contamination reading?

A. [Cordaro, Daverio, Miele]- These steps are set out in Sections 5.3 and 5.8 of OPIP 3.9.2 of the Plan, which are appended to this testimony as Attachment

3. After monitoring personnel conduct a preoperational check of the RM-14 survey meter,

, they will use the RM-14 survey meter with HP-270 probe to record the background radiation level at the relocation center. Monitoring personnel then l Will monitor individuals and subtract the back-ground reading from the RM-14 reading to determine actual thyroid contamination levels. For instance, if the thyroid scan measurement is 450 cpm in a background field of 250 cpm, monitoring personnel simply subtract the 250 background level from the 450 thyroid scan measurement to get the actual thy-roid contamination level of 200 cpm. If an

9 l

l individual's actual thyroid contamination level ex-ceeds 150 cpm (0.13 mR/hr) the individual will be sent to a hospital, as provided in Section 5.8(c) of OPIP 3.9.2.

9. Q. Assuming a normal background reading of 10-15 cpm, is the RM-14 with HP-270 probe sufficiently sensi-tive to accurately measure thyroid contamination levels of 150 cpm (0.13 mR/hr) above background?

A. (Miele] Yes, the RM-14 with HP-270 probe is suffi-ciently sensitive to accurately measure thyroid contamination levels of 150 cpm (0.13 mR/hr) above backgrcund. An action level of 150 cpm above back-ground is only about 30% of full scale of the RM-14 meter's lowest range of 0-500 cpm. A reading of 150 cpm, therefore, is well within the range of the RM-14 and can be read easily.

10. Q. Intervenors allege in Contention 77 that background readings are likely to exceed 50 cpm at relocation centers and that the RM-14 with HP-270 probe is not sufficiently sensitive to accurately measure thy-roid contamination levels of 150 cpm (0.13 mR/hr) when the background reading exceeds 50 cpn. Is that true?

A. [Miele] No. Background radiation levels do not affect the ability to measure thyroid radiation levels with the RM-14 with HP-270 probe unless the background level is over 350 cpm. As was men-tioned in the response to question 8 above, moni-toring personnel simply subtract the background l

l

____________._____.________.____._____________.___._.J

reading from the RM-14 thyroid reading to decermine the actual thyroid contamination level. The RM-14 will be set on its lowest range of 0-500 cpm during thyroid contamination monitoring. Thus, even if the background reading were 350 cpm, a thyroid con-tamination level of 150 cpm could still be read on the RM-14 scale. It is unlikely, however, that background radiation levels at relocation centers would be that high.

s

11. Q. What about the margin of error in the RM-14 reading? Will that affect the ability to accurate-ly measure a thyroid contamination level of 150 cpm?

A. [Miele] Even if the thyroid contamination measure-ments were not exact because of electronic " noise" in the monitoring system, because of variations in gamma ray energies, or for any other reason, it would not detract from the effectiveness of the thyroid contamination monitoring system. The thy-roid scan at relocation centers is intended to pro-vide more of a qualitative measure of the tnyroid contamination level than a quantitative measure.

The monitoring personnel are more concarned about determining if the dose to the thyroid has been substantial enough to be of concern rather than if it is exactly 150 cpm or greater. Thus, as a

l practical matter, monitoring personnel would be concerned that an individual had received a signif-icant dose to the thyroid if the reading were any-where in the range of 150 cpm.

12. Q. But Section 5.3.3 of OPIP 3.9.2 instructs moni-toring personnel to "[e]nsure decontamination fa-cility/ relocation center background radiation lev-els remain less than 50 cpm. This is especially important in those areas where monitoring is per-formed to maintain RM-14 sensitivity." How do you explain this?

A. [Cordaro, Daverio, Miele) This instruction in Sec-tion 5.3.3 of OPIP 3.9.2 was part of an onsite non-emergency procedure in which quantitative accu-racy was essential. It was included inadvertently in OPIP 3.9.2 and will be removed in future revi-sions of the Plan.

13. Q. Will any other equipment be used to measure thyroid contamination levels at relocation centers?

A. [Miele] Yes. In addition to the RM-14 meter with HP-270 probe, an RM-14 meter with a tungsten shielded HP-210 probe will be used at relocation centers that are less than 15 miles from the Shoreham Nuclear Power Station. The manufacturer's description of the HP-210 probe is appended to this testimony as Attachment 4. Use of the RM-14 with a tungsten shielded HP-210 probe at relocation cen-ters within 15 miles of Shoreham will be reflected in future revisions of the LILCO Transition Plan.

l The advantage of the RM-14 meter with the tungsten shielded HP-210 probe is that thyroid contamination levels of 150 cpm can be detected in background ra-diation fields greater than 350 cpm. The tungsten shield makes it possible to monitor for thyroid contamination in a background radiation field at least four times greater than would be possible if an RM-14 meter with HP-270 probe were being used.

This is because the only exposed surface of the tungsten shielded HP-210 probe will be placed on a person's neck over the thyroid area.

14. Q. Please summarize your testimony for Contention 77.

A. [Cordaro, Daverio, Miele] The thyroid monitoring equipment to be used at relocation centers will en-able monitoring personnel to identify those indi-viduals with thyroid dose levels requiring medical attention. Contrary to the assertion in Contention 77 that the RM-14 meter with HP-270 probe is inca-pable of detecting a thyroid contamination level of 150 cpm when the background reading exceeds 50 cpm, radiation levels from thyroid contamination in the range of 150 cpm can be detected in a background field of 350 cpm. -

Moreover, an RM-14 meter with a tungsten shielded HP-210 probe will also be used at relocation cen-ters within 15 miles of the Shoreham Station. The RM-14 meter with a tungsten shielded HP-210 probe can detect thyroid radiation levels in the range of 150 cpm in a background field four times greater than would be possible if an RM-14 raeter with HP-270 probe were being used.

  • Center at Brentwood, they will be monitored by Decontamination Personnel for whole body con-tamination.

5.3 Setting Up Monitoring Operation - Background Radiation Levels ,

5.3.1 Distribute equipment and supplies in facility and set up berriers, signs, and step-off pads as shown in Attachment 5.

A Generalized Floor Plan for a Decontamination Center (Attachment 5) depicts the method Decon-tamination Personnel utilize to rapidly register, isolate contaminated individuals and decontaminate individuals, and process them as " clean." This will be accomplished by using separation barriers, traffic cones, ropes, railings, etc.

5.3.2 Perform preoperational check of the RM-14 survey meter, per Attachment 4, RM-14 Operating Pro-cedure.

5.3.3 Use the RM-14 survey meter with HP-270 probe to determine the general area background radiation level at the decontamination facility / relocation center location. This is done by selecting the "X1" position of the range selector switch and reading the meter indication. Ensure that the probe shield is open. A typical background radiation reading is 10 to 15 counts per minute (CPM) or .01 to .02 mR/hr.

Measure general area background radiation levels per Attachment 4.

Enaure decontamination facility / relocation center background radiation levels remain less than 50 CPM. This is especially important in those areas where monitoring is performed to maintain RM-14 sensitivity.
